88 @cindex Note specification
90 @cindex entering notes
92 The most common syntax for pitch entry is used in @code{\chords} and
93 @code{\notes} mode. In Note and Chord mode, pitches may be designated
94 by names. The notes are specified by the letters @code{a} through
95 @code{g}, while the octave is formed with notes ranging from @code{c}
96 to @code{b}. The pitch @code{c} is an octave below middle C and the
97 letters span the octave above that C.
99 @lilypond[fragment,verbatim]
101 a,4 b, c d e f g a b c' d' e' \clef treble f' g' a' b' c''
104 @cindex note names, Dutch
106 A sharp is formed by adding @code{-is} to the end of a pitch name and
107 a flat is formed by adding @code{-es}. Double sharps and double flats
108 are obtained by adding @code{-isis} or @code{-eses}. These
109 names are the Dutch note names. In Dutch, @code{aes} is contracted to
110 @code{as} in Dutch, but both forms are accepted. Similarly, both
111 @code{es} and @code{ees} are accepted.
113 There are predefined sets of note names for various other languages.
114 To use them, include the language specific init file. For
115 example: @code{\include "english.ly"}. The available language files
116 and the note names they define are:
121 Note Names sharp flat
122 nederlands.ly c d e f g a bes b -is -es
123 english.ly c d e f g a bf b -s/-sharp -f/-flat
124 deutsch.ly c d e f g a b h -is -es
125 norsk.ly c d e f g a b h -iss/-is -ess/-es
126 svenska.ly c d e f g a b h -iss -ess
127 italiano.ly do re mi fa sol la sib si -d -b
128 catalan.ly do re mi fa sol la sib si -d/-s -b
129 espanol.ly do re mi fa sol la sib si -s -b
138 The optional octave specification takes the form of a series of
139 single quote (`@code{'}') characters or a series of comma
140 (`@code{,}') characters. Each @code{'} raises the pitch by one
141 octave; each @code{,} lowers the pitch by an octave.
143 @lilypond[fragment,verbatim,center]
144 c' c'' es' g' as' gisis' ais'
148 There is also a verbose syntax for pitch specification.
151 @cindex @code{\pitch}
153 \pitch @var{scmpitch}
157 where @var{scmpitch} is a Scheme object of the @code{Pitch} type.

174 @node Chromatic alterations
175 @subsection Chromatic alterations
177 Normally accidentals are printed automatically, but you may also
178 print them manually. A reminder accidental
179 @cindex reminder accidental
181 can be forced by adding an exclamation mark @code{!}
182 after the pitch. A cautionary accidental
183 @cindex cautionary accidental
184 @cindex parenthesized accidental
185 (an accidental within parentheses) can be obtained by adding the
186 question mark `@code{?}' after the pitch.

189 cis' cis' cis'! cis'?
193 The automatic production of accidentals can be tuned in many
194 ways. For more information, refer to @ref{Accidentals}.
199 A chord is formed by a enclosing a set of pitches in @code{<<} and
200 @code{>>}. A chord may be followed by a duration, and a set of
201 articulations, just like simple notes.
211 Rests are entered like notes, with the note name @code{r}.
213 @lilypond[singleline,verbatim]
217 Whole bar rests, centered in middle of the bar,
218 must be done with multi measure rests. They are discussed in
219 @ref{Multi measure rests}.
222 A rest's vertical position may be explicitly specified by entering a
223 note with the @code{\rest} keyword appended. This makes manual
224 formatting in polyphonic music easier. Rest collision testing will
225 leave these rests alone.
227 @lilypond[singleline,verbatim]
233 @internalsref{RestEvent}, @internalsref{Rest}
240 @cindex Invisible rest
243 An invisible rest (also called a `skip') can be entered like a note
244 with note name `@code{s}' or with @code{\skip @var{duration}}:
246 @lilypond[singleline,verbatim]
250 The @code{s} syntax is only available in Note mode and Chord mode. In
251 other situations, you should use the @code{\skip} command.
253 @lilypond[singleline,verbatim]
256 { \time 4/8 \skip 2 \time 4/4 }
257 \notes\relative c'' { a2 a1 }
262 The skip command is merely an empty musical placeholder. It does not
263 produce any output, not even transparent output.
267 @internalsref{SkipEvent}
272 @subsection Durations
276 @cindex @code{\duration}
279 In Note, Chord, and Lyrics mode, durations are designated by numbers
280 and dots: durations are entered as their reciprocal values. For example,
281 a quarter note is entered using a @code{4} (since it is a 1/4 note), while
282 a half note is entered using a @code{2} (since it is a 1/2 note). For notes
283 longer than a whole you must use variables.
285 @c FIXME: what is an identifier? I do not think it's been introduced yet.
286 @c and if it has, I obviously skipped that part. - Graham

307 \remove "Staff_symbol_engraver"
308 \remove "Time_signature_engraver"
309 \consists "Pitch_squash_engraver"
316 If the duration is omitted then it is set to the previously entered
317 duration. The default for the first note is a quarter note. The duration
318 can be followed by dots (`@code{.}') in order to obtain dotted note
322 @lilypond[fragment,verbatim,center]
323 a' b' c''8 b' a'4 a'4. b'4.. c'8.
328 You can alter the length of duration by a fraction @var{N/M}
329 appending `@code{*}@var{N/M}' (or `@code{*}@var{N}' if @var{M=1}). This
330 will not affect the appearance of the notes or rests produced.
331 In the following example, the first three notes take up exactly two
333 @lilypond[fragment,relative 2,verbatim]
335 a4*2/3 gis4*2/3 a4*2/3
339 Durations can also be produced using the verbose syntax
340 @code{\duration @var{Scheme object}}.
341 @lilypond[verbatim,fragment]
342 c'\duration #(ly:make-duration 4 1)
349 Dots are normally moved up to avoid staff lines, except in polyphonic
350 situations. The following commands may be used to force a particular
353 @cindex @code{\dotsUp }
355 @cindex @code{\dotsDown }
357 @cindex @code{\dotsBoth}
362 @internalsref{Dots}, @internalsref{DotColumn}.
366 In dense chords, dots can overlap.
371 Whenever a note is found, a
372 @internalsref{Stem} object is created automatically. For whole notes
373 and rests, stem objects are also created, but in those cases, the stem

393 A tie connects two adjacent note heads of the same pitch. The tie in
394 effect extends the length of a note. Ties should not be confused with
395 slurs, which indicate articulation, or phrasing slurs, which indicate
396 musical phrasing. A tie is entered using the tilde symbol `@code{~}'.
398 @lilypond[fragment,verbatim,center]
399 e' ~ e' <<c' e' g'>> ~ <<c' e' g'>>
402 When a tie is applied to a chord, all note heads whose pitches match
403 are connected. When no note heads match, no ties will be created.
405 In its meaning a tie is just a way of extending a note duration, similar
406 to the augmentation dot: the following example are two ways of notating
407 exactly the same concept.

412 If you need to tie a lot of notes over bars, it may be easier to use automatic
413 note splitting (See @ref{Automatic note splitting}).

432 @internalsref{Tie}, @ref{Automatic note splitting}.
435 ties created for a chord, see @inputfileref{input/test,tie-sparse.ly}.
439 Tieing only a subset of the note heads of a pair of chords is not
440 supported in a simple way. It can be achieved by moving the
441 tie-engraver into the @internalsref{Thread} context and turning on and
442 off ties per @internalsref{Thread}.
444 Switching staves when a tie is active, will not produce a slanted tie.
446 Formatting of ties is a difficult subject. The results are often not
456 @cindex @code{\times}
458 Tuplets are made out of a music expression by multiplying all durations
461 @cindex @code{\times}
463 \times @var{fraction} @var{musicexpr}
466 The duration of @var{musicexpr} will be multiplied by the fraction.
467 In the sheet music, the fraction's denominator will be printed over
468 the notes, optionally with a bracket. The most common tuplet is the
469 triplet in which 3 notes have the length of 2, so the notes are 2/3
470 of their written length:
472 @lilypond[fragment,verbatim,center]
473 g'4 \times 2/3 {c'4 c' c'} d'4 d'4
476 The property @code{tupletSpannerDuration} specifies how long each
477 bracket should last. With this, you can make lots of tuplets while
478 typing @code{\times} only once, saving lots of typing. In the next
479 example, there are two triplets shown, while @code{\times} was only
482 @lilypond[fragment, relative, singleline, verbatim]
483 \property Voice.tupletSpannerDuration = #(ly:make-moment 1 4)
484 \times 2/3 { c'8 c c c c c }
487 The format of the number is determined by the property
488 @code{tupletNumberFormatFunction}. The default prints only the
489 denominator, but if it is set to the Scheme function
490 @code{fraction-tuplet-formatter}, @var{num}:@var{den} will be printed
494 @cindex @code{tupletNumberFormatFunction}

502 @cindex @code{\tupletDown }
504 @cindex @code{\tupletBoth}

513 Nested tuplets are not formatted automatically. In this case, outer
514 tuplet brackets should be moved manually.

532 The @code{EasyNotation} variable overrides a @internalsref{Score}
533 context. You probably will want to print it with magnification or a
534 large font size to make it more readable. To print with
535 magnification, you must create a DVI file (with @file{ly2dvi}) and
536 then enlarge it with something like @file{dvips -x 2000 file.dvi}.
537 See the @code{dvips} documentation for more details. To print with a
538 larger font, see @ref{Font Size}.
544 If you view the result with Xdvi, then staff lines will show through

577 @subsection Relative octaves
579 @cindex relative octave specification
581 Octaves are specified by adding @code{'} and @code{,} to pitch names.
582 When you copy existing music, it is easy to accidentally put a pitch
583 in the wrong octave and hard to find such an error. The relative
584 octave mode prevents these errors: a single error puts the rest of the
585 piece off by one octave.
587 @cindex @code{\relative}
589 \relative @var{startpitch} @var{musicexpr}
592 The octave of notes that appear in @var{musicexpr} are calculated as
593 follows: If no octave changing marks are used, the basic interval
594 between this and the last note is always taken to be a fourth or less
595 (This distance is determined without regarding alterations; a
596 @code{fisis} following a @code{ceses} will be put above the
599 The octave changing marks @code{'} and @code{,} can be added to raise
600 or lower the pitch by an extra octave. Upon entering relative mode,
601 an absolute starting pitch must be specified that will act as the
602 predecessor of the first note of @var{musicexpr}.
604 Here is the relative mode shown in action:

648 Bar checks help detect errors in the durations. A bar check is

1065 In scores with many staves, a @code{\bar} command in one staff is
1066 automatically applied to all staffs. The resulting bar lines are
1067 connected between different staves of a @internalsref{StaffGroup}:
1069 @lilypond[fragment, verbatim]
1070 < \context StaffGroup <
1071 \context Staff = up { e'4 d'
1074 \context Staff = down { \clef bass c4 g e g } >
1075 \context Staff = pedal { \clef bass c2 c2 } >
1079 The command @code{\bar @var{bartype}} is a short cut for doing
1080 @code{\property Score.whichBar = @var{bartype}} Whenever
1081 @code{whichBar} is set to a string, a bar line of that type is
1082 created. At the start of a measure it is set to
1083 @code{defaultBarType}. The contents of @code{repeatCommands} are used
1084 to override default measure bars.
1086 @code{whichBar} can also be set directly, using @code{\property} or
1087 @code{\bar}. These settings take precedence over the automatic
1088 @code{whichBar} settings.
1091 @cindex repeatCommands
1092 @cindex defaultBarType
1094 You are encouraged to use @code{\repeat} for repetitions. See
1104 The bar line objects that are created at @internalsref{Staff} level
1105 are called @internalsref{BarLine}, the bar lines that span staffs are
1106 @internalsref{SpanBar}s.
1113 The easiest way to enter fragments with more than one voice on a staff
1114 is to split chords using the separator @code{\\}. You can use it for
1115 small, short-lived voices or for single chords:
1117 @lilypond[verbatim,fragment]
1118 \context Voice = VA \relative c'' {
1119 c4 < { f d e } \\ { b c2 } > c4 < g' \\ b, \\ f' \\ d >
1123 The separator causes @internalsref{Voice} contexts to be
1125 bear the names @code{"1"}, @code{"2"}, etc. In each of these
1126 contexts, vertical direction of slurs, stems, etc. is set
1129 This can also be done by instantiating @internalsref{Voice} contexts
1130 by hand, and using @code{\voiceOne}, up to @code{\voiceFour} to assign
1131 a stem directions and horizontal shift for each part.
1134 @lilypond[singleline, verbatim]
1136 \context Staff < \context Voice = VA { \voiceOne cis2 b }
1137 \context Voice = VB { \voiceThree b4 ais ~ ais4 gis4 }
1138 \context Voice = VC { \voiceTwo fis4~ fis4 f ~ f } >
1141 Normally, note heads with a different number of dots are not merged, but
1142 when the object property @code{merge-differently-dotted} is set in
1143 the @internalsref{NoteCollision} object, they are:
1144 @lilypond[verbatim,fragment,singleline]
1145 \relative c'' \context Voice < {
1147 \property Staff.NoteCollision \override
1148 #'merge-differently-dotted = ##t
1150 } \\ { g8.-[ f16-] g8.-[ f16-] }
1154 Similarly, you can merge half note heads with eighth notes, by setting
1155 @code{merge-differently-headed}:
1156 @lilypond[fragment, relative=2,verbatim]
1159 \property Staff.NoteCollision
1160 \override #'merge-differently-headed = ##t
1161 c8 c4. } \\ { c2 c2 } >
1164 LilyPond also vertically shifts rests that are opposite of a stem.

1187 The following commands specify in what chords of the current voice
1188 should be shifted: the outer voice has @code{\shiftOff}, and the inner
1189 voices have @code{\shiftOn}, @code{\shiftOnn}, etc.
1192 @cindex @code{\shiftOn}
1194 @cindex @code{\shiftOnn}

1205 The objects responsible for resolving collisions are
1206 @internalsref{NoteCollision} and @internalsref{RestCollision}. See
1207 also example files @inputfileref{input/regression,collision-dots.ly},

1211 @inputfileref{input/regression,collisions.ly}.
1216 Resolving collisions is a intricate subject, and only a few situations
1217 are handled. When LilyPond cannot cope, the @code{force-hshift}
1218 property of the @internalsref{NoteColumn} object and pitched rests can
1219 be used to override typesetting decisions.
1221 When using @code{merge-differently-headed} with upstem 8th or shorter
1222 note, and a downstem half note, the 8th note gets the wrong offset.
1227 Beams are used to group short notes into chunks that are aligned with
1228 the metrum. They are inserted automatically in most cases.

1236 that differ from the defaults.

1249 In some cases it may be necessary to override the automatic beaming

1263 When this mechanism fouls up, the properties

1319 One of the strong points of LilyPond is how beams are formatted. Beams
1320 are quantized, meaning that the left and right endpoints beams start
1321 exactly on staff lines. Without quantization, small wedges of white
1322 space appear between the beam and staff line, and this looks untidy.
1324 Beams are also slope-damped: melodies that go up or down should also
1325 have beams that go up or down, but the slope of the beams should be
1326 less than the slope of the notes themselves.
1328 Some beams should be horizontal. These are so-called concave beams.

1343 @c [TODO: use \applycontext]
1345 In normal time signatures, automatic beams can start on any note but can
1346 only end in a few positions within the measure: beams can end on a beat,
1347 or at durations specified by the properties in
1348 @code{Voice.autoBeamSettings}. The defaults for @code{autoBeamSettings}
1349 are defined in @file{scm/auto-beam.scm}.
1351 The value of @code{autoBeamSettings} is changed using
1352 @code{\override} and restored with @code{\revert}:
1354 \property Voice.autoBeamSettings \override #'(@var{BE} @var{P} @var{Q} @var{N} @var{M}) = @var{dur}
1355 \property Voice.autoBeamSettings \revert #'(@var{BE} @var{P} @var{Q} @var{N} @var{M})
1357 Here, @var{BE} is the symbol @code{begin} or @code{end}. It determines
1358 whether the rule applies to begin or end-points. The quantity
1359 @var{P}/@var{Q} refers to the length of the beamed notes (and `@code{*
1360 *}' designates notes of any length), @var{N}/@var{M} refers to a time
1361 signature (wildcards, `@code{* *}' may be entered to designate all time
1364 For example, if automatic beams should end on every quarter note, use
1367 \property Voice.autoBeamSettings \override
1368 #'(end * * * *) = #(ly:make-moment 1 4)
1370 Since the duration of a quarter note is 1/4 of a whole note, it is
1371 entered as @code{(ly:make-moment 1 4)}.
1373 The same syntax can be used to specify beam starting points. In this
1374 example, automatic beams can only end on a dotted quarter note.
1376 \property Voice.autoBeamSettings \override
1377 #'(end * * * *) = #(ly:make-moment 3 8)
1379 In 4/4 time signature, this means that automatic beams could end only on
1380 3/8 and on the fourth beat of the measure (after 3/4, that is 2 times
1381 3/8 has passed within the measure).
1383 Rules can also be restricted to specific time signatures. A rule that
1384 should only be applied in @var{N}/@var{M} time signature is formed by
1385 replacing the second asterisks by @var{N} and @var{M}. For example, a
1386 rule for 6/8 time exclusively looks like
1388 \property Voice.autoBeamSettings \override
1389 #'(begin * * 6 8) = ...
1392 If a rule should be to applied only to certain types of beams, use the
1393 first pair of asterisks. Beams are classified according to the
1394 shortest note they contain. For a beam ending rule that only applies
1395 to beams with 32nd notes (and no shorter notes), use @code{(end 1 32 *
1398 If a score ends while an automatic beam has not been ended and is still
1399 accepting notes, this last beam will not be typeset at all.

1403 @cindex @code{Voice.autoBeaming}

1413 @code{\autoBeamOff},
1414 @cindex @code{\autoBeamOn }
1420 It is not possible to specify beaming parameters for beams with mixed
1421 durations, that differ from the beaming parameters of all separate
1422 durations, i.e., you will have to specify manual beams to get:
1424 @lilypond[singleline,fragment,relative,noverbatim,quote]

1427 \time 12/8 c'8 c c c16 c c c c c c-[ c c c-] c8 c c4
1429 It is not possible to specify beaming parameters that act differently in
1430 different parts of a measure. This means that it is not possible to use
1431 automatic beaming in irregular meters such as @code{5/8}.

1446 @node Using the predefined accidental variables
1447 @subsection Using the predefined accidental variables
1449 The constructs for describing the accidental typesetting rules are
1450 quite hairy, so non-experts should stick to the variables
1451 defined in @file{ly/property-init.ly}.
1452 @cindex @file{property-init.ly}
1454 The variables set properties in the ``@code{Current}'' context (see
1455 @ref{Context properties}). This means that the variables should
1456 normally be added right after the creation of the context in which the
1457 accidental typesetting described by the variable is to take
1458 effect. For example, if you want to use piano-accidentals in a piano
1459 staff then issue @code{\pianoAccidentals} first thing after the
1460 creation of the piano staff:
1463 \notes \relative c'' <
1464 \context Staff = sa @{ cis4 d e2 @}
1465 \context GrandStaff <
1467 \context Staff = sb @{ cis4 d e2 @}
1468 \context Staff = sc @{ es2 c @}

1481 \context Staff = sc { es2 c }
1483 \context Staff = sd { es2 c }
1488 minimumVerticalExtent = #'(-4.0 . 4.0)
1496 @item \defaultAccidentals
1497 @cindex @code{\defaultAccidentals}
1498 This is the default typesetting behaviour. It should correspond
1499 to 18th century common practice: Accidentals are
1500 remembered to the end of the measure in which they occur and
1501 only on their own octave.
1503 @item \voiceAccidentals
1504 @cindex @code{\voiceAccidentals}
1506 The normal behaviour is to
1507 remember the accidentals on Staff-level. This variable, however,
1508 typesets accidentals individually for each voice. Apart from that the
1509 rule is similar to @code{\defaultAccidentals}.
1511 This leads to some weird and often unwanted results
1512 because accidentals from one voice do not get cancelled in other
1514 @lilypond[singleline,relative,fragment,verbatim,quote]
1522 Hence you should only use @code{\voiceAccidentals} if the voices
1523 are to be read solely by individual musicians. If the staff is to be
1524 used by one musician (e.g., a conductor) then you use
1525 @code{\modernVoiceAccidentals} or @code{\modernVoiceCautionaries}
1528 @item \modernAccidentals
1529 @cindex @code{\modernAccidentals}
1530 This rule corresponds to the common practice in the 20th
1532 The rule is more complex than @code{\defaultAccidentals}.
1533 You get all the same accidentals, but temporary
1534 accidentals also get cancelled in other octaves. Further more,
1535 in the same octave, they also get cancelled in the following measure:
1536 @lilypond[singleline,fragment,verbatim]
1538 cis' c'' cis'2 | c'' c'
1541 @item \modernCautionaries
1542 @cindex @code{\modernCautionaries}
1543 This rule is similar to @code{\modernAccidentals}, but the
1544 ``extra'' accidentals (the ones not typeset by
1545 @code{\defaultAccidentals}) are typeset as cautionary accidentals.
1546 They are printed in reduced size or with parentheses.

1554 is used for multivoice accidentals to be read both by musicians
1555 playing one voice and musicians playing all voices. Accidentals are
1556 typeset for each voice, but they @emph{are} cancelled across voices in
1557 the same @internalsref{Staff}.
1559 @cindex @code{\modernVoiceCautionaries}
1560 @item \modernVoiceCautionaries
1561 is the same as @code{\modernVoiceAccidentals}, but with the extra
1562 accidentals (the ones not typeset by @code{\voiceAccidentals}) typeset
1563 as cautionaries. Even though all accidentals typeset by

1659 Currently the simultaneous notes are considered to be entered in
1660 sequential mode. This means that in a chord the accidentals are
1661 typeset as if the notes in the chord happened one at a time - in the
1662 order in which they appear in the input file.
1664 This is only a problem when there are simultaneous notes whose
1665 accidentals depend on each other. The problem only occurs when using
1666 non-default accidentals. In the default scheme, accidentals only
1667 depend on other accidentals with the same pitch on the same staff, so
1668 no conflicts possible.
1670 This example shows two examples of the same music giving different

2059 It is possible to place arbitrary strings of text or markup text (see

2061 @code{c^"text"}. By default, these indications do not influence the
2062 note spacing, but by using the command @code{\fatText}, the widths
2063 will be taken into account.
2065 @lilypond[fragment,singleline,verbatim] \relative c' {

2082 @subsection Grace notes
2084 @cindex @code{\grace}
2088 Grace notes are ornaments that are written out
2090 @lilypond[relative=2,verbatim,fragment] c4 \grace c16 c4 \grace {
2094 In normal notation, grace notes take up no logical
2095 time in a measure. Such an idea is practical for normal notation, but
2096 is not strict enough to put it into a program. The model that LilyPond
2097 uses for grace notes internally is that all timing is done in two
2100 Every point in musical time consists of two rational numbers: one
2101 denotes the logical time, one denotes the grace timing. The above
2102 example is shown here with timing tuples.
2105 \score { \notes \relative c''{
2106 c4^"(0,0)" \grace c16_" "_"(1/4,-1/16)" c4^"(1/4,0)" \grace {
2107 c16_"(2/4,-1/8)"-[ d16^"(2/4,-1/16)" ] } c4_" "_"(2/4,0)"
2109 \paper { linewidth = 12.\cm }
2114 The placement of grace notes is synchronized between different staves.
2115 In the following example, there are two sixteenth graces notes for
2116 every eighth grace note.
2118 @lilypond[relative=2,verbatim,fragment]
2119 < \context Staff = SA { e4 \grace { c16-[ d e f-] } e4 }
2120 \context Staff = SB { c'4 \grace { g8-[ b-] } c4 } >
2124 Unbeamed eighth notes and shorter by default have a slash through the
2125 stem. This can be controlled with object property @code{stroke-style} of
2126 @internalsref{Stem}. For proper matching of override and reverts of
2127 such properties, it is necessary to use a Scheme function.
2129 The following fragment overrides the default formatting Grace style stems.
2131 #(add-to-grace-init "Voice" 'Stem 'stroke-style '())
2134 The @code{\override} is carefully matched with a @code{\revert}.
2139 @lilypond[fragment,verbatim]
2140 \relative c'' \context Voice {
2141 \grace c8 c4 \grace { c16-[ c16-] } c4
2143 \property Voice.Stem \override #'stroke-style = #'()
2145 \property Voice.Stem \revert #'stroke-style
2150 If you want to end a note with a grace note, then the standard trick
2151 is to put the grace notes before a phantom ``space note'', e.g.
2152 @lilypond[fragment,verbatim, relative=2]
2155 { s2 \grace { c16-[ d-] } } >
2161 By adjusting the duration of the skip note (here it is a half-note),
2162 the space between the main-note and the grace is adjusted.
2164 A @code{\grace} section has some default values, and LilyPond will
2165 use those default values unless you specify otherwise inside the
2166 @code{\grace} section. For example, if you specify \slurUp
2167 @emph{before} your @code{\grace} section, a slur which starts inside
2168 the @code{\grace} will not be forced up, even if the slur ends outside
2169 of the @code{\grace}. Note the difference between the first and
2170 second bars in this example:
2172 @lilypond[fragment,verbatim]
2173 \relative c'' \context Voice {
2191 @internalsref{GraceMusic},
2195 Grace notes cannot be used in the smallest size (@file{paper11.ly}).
2197 A score that starts with an @code{\grace} section needs an explicit
2198 @code{\context Voice} declaration, otherwise the main note and grace
2199 note end up on different staffs.
2201 Grace note synchronization can also lead to surprises. Staff notation,
2202 such as key signatures, barlines, etc. are also synchronized. Take
2203 care when you mix staves with grace notes and staves without, for example:
2205 @lilypond[relative=2,verbatim,fragment]
2206 < \context Staff = SA { e4 \bar "|:" \grace c16 d4 }
2207 \context Staff = SB { c4 \bar "|:" d4 } >
2210 Grace sections should only be used within sequential music
2211 expressions. Nesting or juxtaposing grace sections is not supported,
2212 and might produce crashes or other errors.
2214 Overriding settings for grace music globally cannot be done in a
2215 modular way. A kludge (@code{add-to-grace-init}) is defined in
2216 @file{ly/grace-init.ly}.
2220 @subsection Glissando
2223 @cindex @code{\glissando}
2225 A glissando is a smooth change in pitch. It is denoted by a line or a
2226 wavy line between two notes.
2230 A glissando line can be requested by attaching a @code{\glissando} to
2233 @lilypond[fragment,relative,verbatim]
2239 @internalsref{Glissando}, @internalsref{GlissandoEvent}.
2244 Additional texts (such as @emph{gliss.}) is not supported.
2248 @subsection Dynamics
2261 @cindex @code{\ffff}
2271 Absolute dynamic marks are specified using an variable after a
2272 note: @code{c4-\ff}. The available dynamic marks are: @code{\ppp},
2273 @code{\pp}, @code{\p}, @code{\mp}, @code{\mf}, @code{\f}, @code{\ff},
2274 @code{\fff}, @code{\fff}, @code{\fp}, @code{\sf}, @code{\sff},
2275 @code{\sp}, @code{\spp}, @code{\sfz}, and @code{\rfz}.

2278 c'-\ppp c-\pp c -\p c-\mp c-\mf c-\f c-\ff c-\fff
2284 @cindex @code{\decr}
2285 @cindex @code{\rced}
2292 A crescendo mark is started with @code{\<} and terminated with
2293 @code{\!}. A decrescendo is started with @code{\>} and also terminated
2294 with @code{\!}. Because these marks are bound to notes, if you must
2295 use spacer notes if multiple marks during one note are needed.
2297 @lilypond[fragment,verbatim,center,quote]
2298 c''-\< c''-\! d''-\decr e''-\rced
2299 < f''1 { s4 s4-\< s4-\! \> s4-\! } >
2301 This may give rise to very short hairpins. Use @code{minimum-length}
2302 in @internalsref{Voice}.@internalsref{HairPin} to lengthen them, for
2306 \property Staff.Hairpin \override #'minimum-length = #5
2309 You can also use a text saying @emph{cresc.} instead of hairpins. Here
2310 is an example how to do it:
2312 @lilypond[fragment,relative=2,verbatim]
2313 c4 \cresc c4 c c c \endcresc c4
2319 You can also supply your own texts:
2320 @lilypond[fragment,relative,verbatim]
2322 \property Voice.crescendoText = \markup { \italic "cresc. poco" }
2323 \property Voice.crescendoSpanner = #'dashed-line

2340 @cindex direction, of dynamics
2344 @internalsref{CrescendoEvent}, @internalsref{DecrescendoEvent},
2345 @internalsref{AbsoluteDynamicEvent}.
2347 Dynamics are objects of @internalsref{DynamicText} and
2348 @internalsref{Hairpin}. Vertical positioning of these symbols is
2349 handled by the @internalsref{DynamicLineSpanner} object.
2351 If you want to adjust padding or vertical direction of the dynamics,
2352 you must set properties for the @internalsref{DynamicLineSpanner}
2361 @cindex @code{\repeat}
2364 Repetition is a central concept in music, and multiple notations exist
2365 for repetitions. In LilyPond, most of these notations can be captured
2366 in a uniform syntax. One of the advantages is, all these repetitions
2367 can be rendered in MIDI accurately.
2369 The following types of repetition are supported:
2373 Repeated music is fully written (played) out. Useful for MIDI
2374 output, and entering repetitive music.
2377 This is the normal notation: Repeats are not written out, but
2378 alternative endings (voltas) are printed, left to right.
2382 Alternative endings are written stacked. This has limited use but may be
2383 used to typeset two lines of lyrics in songs with repeats, see
2384 @inputfileref{input,star-spangled-banner.ly}.
2391 Make beat or measure repeats. These look like percent signs.
2397 * Repeats and MIDI::
2398 * Manual repeat commands::
2400 * Tremolo subdivisions::
2405 @subsection Repeat syntax
2409 LilyPond has one syntactic construct for specifying different types of
2410 repeats. The syntax is
2413 \repeat @var{variant} @var{repeatcount} @var{repeatbody}
2416 If you have alternative endings, you may add
2417 @cindex @code{\alternative}
2419 \alternative @code{@{} @var{alternative1}
2421 @var{alternative3} @dots{} @code{@}}
2423 where each @var{alternative} is a music expression. If you do not
2424 give enough alternatives for all of the repeats, then the first
2425 alternative is assumed to be played more than once.
2427 Normal notation repeats are used like this:
2428 @lilypond[fragment,verbatim]
2430 \repeat volta 2 { c'4 d' e' f' }
2431 \repeat volta 2 { f' e' d' c' }
2434 With alternative endings:
2435 @lilypond[fragment,verbatim]
2437 \repeat volta 2 {c'4 d' e' f'}
2438 \alternative { {d'2 d'} {f' f} }
2442 @lilypond[fragment,verbatim]
2446 \repeat volta 4 { e | c2 d2 | e2 f2 | }
2447 \alternative { { g4 g g } { a | a a a a | b2. } }
2454 If you do a nested repeat like
2463 then it is ambiguous to which @code{\repeat} the @code{\alternative}
2464 belongs. This ambiguity is resolved by always having the
2465 @code{\alternative} belong to the inner @code{\repeat}. For clarity,
2466 it is advisable to use braces in such situations.

2621 @subsection Percussion staves
2625 A percussion part for more than one instrument typically uses a
2626 multiline staff where each position in the staff refers to one piece
2631 Percussion staves are typeset with help of a set of Scheme
2632 functions. The system is based on the general MIDI drum-pitches.
2633 Include @file{drumpitch-init.ly} to use drum pitches. This file
2634 defines the pitches from the Scheme variable @code{drum-pitch-names},
2635 the definition of which can be read in @file{scm/drums.scm}. Each
2636 piece of percussion has a full name and an abbreviated name, and both
2637 the full name or the abbreviation may be used in input files.
2639 To typeset the music on a staff apply the function @code{drums->paper}
2640 to the percussion music. This function takes a list of percussion
2641 instrument names, notehead scripts and staff positions (that is:
2642 pitches relative to the C-clef) and transforms the input
2643 music by moving the pitch, changing the notehead and (optionally)

2883 @subsection Percussion MIDI output
2885 In order to produce correct MIDI output you need to produce two score
2886 blocks---one for the paper and one for the MIDI output. To use the
2887 percussion channel you set the property @code{instrument} to
2888 @code{'drums}. Because the drum-pitches themselves are similar to the
2889 general MIDI pitches all you have to do is to insert the voices with
2890 none of the scheme functions to get the correct MIDI output:

2916 @section Piano music
2918 Piano staves are two normal staves coupled with a brace. The staves
2919 are largely independent, but sometimes voices can cross between the
2920 two staves. The same notation is also used for harps and other key
2921 instruments. The @internalsref{PianoStaff} is especially built to
2922 handle this cross-staffing behavior. In this section we discuss the
2923 @internalsref{PianoStaff} and some other pianistic peculiarities.
2927 * Automatic staff changes::
2928 * Manual staff switches::
2931 * Staff switch lines::
2936 There is no support for putting chords across staves. You can get
2937 this result by increasing the length of the stem in the lower stave so
2938 it reaches the stem in the upper stave, or vice versa. An example is
2939 included with the distribution as @inputfileref{input/test,stem-cross-staff.ly}.

2955 @subsection Automatic staff changes
2956 @cindex Automatic staff changes
2958 Voices can switch automatically between the top and the bottom
2959 staff. The syntax for this is
2961 \autochange Staff \context Voice @{ @dots{}@var{music}@dots{} @}
2963 The autochanger switches on basis of pitch (central C is the turning
2964 point), and it looks ahead skipping over rests to switch in
2965 advance. Here is a practical example:
2967 @lilypond[verbatim,singleline,quote]
2968 \score { \notes \context PianoStaff <
2969 \context Staff = "up" {
2970 \autochange Staff \context Voice = VA < \relative c' {
2971 g4 a b c d r4 a g } > }
2972 \context Staff = "down" {
2979 In this example, spacer rests are used to prevent the bottom staff from
2980 terminating too soon.
2985 The staff switches often do not end up in optimal places. For high
2986 quality output staff switches should be specified manually.
2990 @node Manual staff switches
2991 @subsection Manual staff switches
2993 @cindex manual staff switches
2994 @cindex staff switch, manual
2996 Voices can be switched between staves manually, using the following command:
2998 \translator Staff = @var{staffname} @var{music}
3002 The string @var{staffname} is the name of the staff. It switches the
3003 current voice from its current staff to the Staff called
3004 @var{staffname}. Typically @var{staffname} is @code{"up"} or
3012 Pianos have pedals that alter the way sound are produced. Generally, a
3013 piano has three pedals, sustain, una corda, and sostenuto.
3017 Piano pedal instruction can be expressed by attaching
3018 @code{\sustainDown}, @code{\sustainUp}, @code{\unaCorda},
3019 @code{\treCorde}, @code{\sostenutoDown} and @code{\sostenutoUp} to a
3022 @lilypond[fragment,verbatim]
3023 c'4-\sustainDown c'4-\sustainUp
3026 What is printed can be modified by setting @code{pedal@var{X}Strings},
3027 where @var{X} is one of the pedal types: @code{Sustain},
3028 @code{Sostenuto} or @code{UnaCorda}. Refer to the generated
3029 documentation of @internalsref{SustainPedal} for more information.
3031 Pedals can also be indicated by a sequence of brackets, by setting the
3032 @code{pedalSustainStyle} property to @code{bracket} objects:
3034 @lilypond[fragment,verbatim]
3035 \property Staff.pedalSustainStyle = #'bracket
3036 c''4-\sustainDown d''4 e''4
3037 a'4-\sustainUp-\sustainDown
3038 f'4 g'4 a'4-\sustainUp
3041 A third style of pedal notation is a mixture of text and brackets,
3042 obtained by setting @code{pedal-type} to @code{mixed}:
3044 @lilypond[fragment,verbatim]
3045 \property Staff.pedalSustainStyle = #'mixed
3046 c''4-\sustainDown d''4 e''4
3047 c'4-\sustainUp-\sustainDown
3048 f'4 g'4 a'4-\sustainUp
3051 The default `*Ped' style for sustain and damper pedals corresponds to
3052 @code{\pedal-type = #'text}. However, @code{mixed} is the default style
3053 for a sostenuto pedal:
3055 @lilypond[fragment,verbatim]
3056 c''4-\sostenutoDown d''4 e''4 c'4 f'4 g'4 a'4-\sostenutoUp
3059 For fine-tuning of the appearance of a pedal bracket, the properties
3060 @code{edge-width}, @code{edge-height}, and @code{shorten-pair} of
3061 @code{PianoPedalBracket} objects (see the detailed documentation of
3062 @internalsref{PianoPedalBracket}) can be modified. For example, the bracket
3063 may be extended to the end of the note head.
3065 @lilypond[fragment,verbatim]
3066 \property Staff.PianoPedalBracket \override
3067 #'shorten-pair = #'(0 . -1.0)

3076 @cindex broken arpeggio
3077 @cindex @code{\arpeggio}
3079 You can specify an arpeggio sign on a chord by attaching an
3080 @code{\arpeggio} to a chord.
3083 @lilypond[fragment,relative,verbatim]
3084 <<c e g c>>-\arpeggio
3087 When an arpeggio crosses staves, you attach an arpeggio to the chords
3088 in both staves, and set
3089 @internalsref{PianoStaff}.@code{connectArpeggios}.
3091 @lilypond[fragment,relative,verbatim]

3095 \context Voice = other { \clef bass <<c,, e g>>-\arpeggio }
3099 The direction of the arpeggio is sometimes denoted by adding an
3100 arrowhead to the wiggly line. This can be typeset by setting
3101 @code{arpeggio-direction}.
3103 @lilypond[fragment,relative,verbatim]
3105 \property Voice.Arpeggio \set #'arpeggio-direction = #1

3108 <<c e g c>>-\arpeggio
3112 A square bracket on the left indicates that the player should not
3113 arpeggiate the chord. To draw these brackets, set the
3114 @code{molecule-callback} property of @code{Arpeggio} or
3115 @code{PianoStaff.Arpeggio} objects to @code{\arpeggioBracket}, and use
3116 @code{\arpeggio} statements within the chords as before.

3181 This section discusses how to enter and print lyrics.
3185 * The Lyrics context::
3190 @node Entering lyrics
3191 @subsection Entering lyrics
3195 @cindex @code{\lyrics}
3198 Lyrics are entered in a special input mode. This mode is is introduced
3199 by the keyword @code{\lyrics}. In this mode you can enter lyrics, with
3200 punctuation and accents without any hassle. Syllables are entered like
3201 notes, but with pitches replaced by text. For example,
3203 \lyrics @{ Twin-4 kle4 twin- kle litt- le star2 @}
3206 A word in Lyrics mode begins with: an alphabetic character, @code{_},
3207 @code{?}, @code{!}, @code{:}, @code{'}, the control characters @code{^A}
3208 through @code{^F}, @code{^Q} through @code{^W}, @code{^Y}, @code{^^},
3209 any 8-bit character with ASCII code over 127, or a two-character
3210 combination of a backslash followed by one of @code{`}, @code{'},
3211 @code{"}, or @code{^}.
3213 Subsequent characters of a word can be any character that is not a digit
3214 and not white space. One important consequence of this is that a word
3215 can end with @code{@}}. The following example is usually a bug. The
3216 syllable includes a @code{@}}, and hence the opening brace is not balanced.
3218 \lyrics @{ twinkle@}
3221 @cindex @code{\property}, in @code{\lyrics}
3222 Similarly, a period following a alphabetic sequence, is included in the
3223 resulting string. As a consequence, spaces must be inserted around
3224 @code{\property} commands:
3226 \property Lyrics . LyricText \set #'font-shape = #'italic
3230 @cindex spaces, in lyrics
3231 @cindex quotes, in lyrics
3233 Any @code{_} character which appears in an unquoted word is converted
3234 to a space. This provides a mechanism for introducing spaces into words
3235 without using quotes. Quoted words can also be used in Lyrics mode to
3236 specify words that cannot be written with the above rules:
3239 \lyrics @{ He said: "\"Let" my peo ple "go\"" @}
3243 Hyphens can be entered as ordinary hyphens at the end of a syllable, i.e.
3248 These will be attached to the end of the first syllable.
3250 Centered hyphens are entered using the special `@code{-}@code{-}' lyric
3251 as a separate word between syllables. The hyphen will have variable
3252 length depending on the space between the syllables and it will be
3253 centered between the syllables.
3258 When a lyric is sung over many notes (this is called a melisma), this is
3259 indicated with a horizontal line centered between a syllable and the
3260 next one. Such a line is called an extender line, and it is entered as
3265 @internalsref{LyricEvent}, @internalsref{HyphenEvent},
3266 @internalsref{ExtenderEvent}.
3270 The definition of lyrics mode is too complex.
3272 @node The Lyrics context
3273 @subsection The Lyrics context
3275 Lyrics are printed by interpreting them in @internalsref{Lyrics}
3278 \context Lyrics \lyrics @dots{}
3281 @cindex automatic syllable durations
3282 @cindex @code{\addlyrics}
3283 @cindex lyrics and melodies
3285 This will place the lyrics according to the durations that were
3286 entered. The lyrics can also be aligned under a given melody
3287 automatically. In this case, it is no longer necessary to enter the
3288 correct duration for each syllable. This is achieved by combining the
3289 melody and the lyrics with the @code{\addlyrics} expression
3293 \context Lyrics @dots{}
3296 @cindex staff order, with @code{\addlyrics}
3298 Normally, this will put the lyrics below the staff. For different or
3299 more complex orderings, the best way is to setup the hierarchy of
3300 staffs and lyrics first, e.g.
3302 \context ChoirStaff \notes <
3303 \context Lyrics = LA @{ s1 @}
3304 \context Staff = SA @{ s1 @}
3305 \context Lyrics = LB @{ s1 @}
3306 \context Staff = SB @{ s1 @}
3309 and then combine the appropriate melodies and lyric lines:
3312 \context Staff = SA @emph{the music}
3313 \context Lyrics = LA @emph{the lyrics}
3316 putting both together, you would get
3318 \context ChoirStaff \notes <
3319 \context Lyrics = LA @dots{}
3320 \context Staff = SB @dots{}
3326 @cindex choral score
3328 A complete example of a SATB score setup is in the file
3329 @inputfileref{input/template,satb}.
3333 @internalsref{LyricCombineMusic}, @internalsref{Lyrics},
3334 @inputfileref{input/template,satb}.
3338 @code{\addlyrics} is not automatic enough: melismata are not detected
3339 automatically, and melismata are not stopped when they hit a rest. A
3340 melisma on the last note in a melody is not printed.
3344 @subsection More stanzas
3347 @cindex phrasing, in lyrics
3349 When multiple stanzas are printed underneath each other, the vertical
3350 groups of syllables should be aligned around punctuation. This can be
3351 done automatically when corresponding lyric lines and melodies are
3354 To this end, give the @internalsref{Voice} context an identity,
3356 \context Voice = duet @{
3361 Then set the @internalsref{LyricsVoice} contexts to names starting with
3362 that identity followed by a dash. In the preceding example, the
3363 @internalsref{Voice} identity is @code{duet}, so the identities of the
3364 @internalsref{LyricsVoices} are marked @code{duet-1} and @code{duet-2}.
3366 \context LyricsVoice = "duet-1" @{
3367 Hi, my name is bert. @}
3368 \context LyricsVoice = "duet-2" @{
3369 Ooooo, ch\'e -- ri, je t'aime. @}
3371 The convention for naming @internalsref{LyricsVoice} and
3372 @internalsref{Voice} must also be used to get melismata correct in
3373 conjunction with rests.
3375 The complete example is shown here.
3376 @lilypond[singleline,verbatim]
3379 \notes \relative c'' \context Voice = duet { \time 3/4
3381 \lyrics \context Lyrics <
3382 \context LyricsVoice = "duet-1" {
3383 \property LyricsVoice . stanza = "Bert"
3384 Hi, my name is bert. }
3385 \context LyricsVoice = "duet-2" {
3386 \property LyricsVoice . stanza = "Ernie"
3387 Ooooo, ch\'e -- ri, je t'aime. }
3392 Stanza numbers, or the names of the singers can be added by setting
3393 @code{LyricsVoice.Stanza} (for the first system) and
3394 @code{LyricsVoice.stz} for the following systems. Notice how dots are
3395 surrounded with spaces in @code{\lyrics} mode.
3398 \property LyricsVoice . stanza = "Bert"
3400 \property LyricsVoice . stanza = "Ernie"
3403 To make empty spaces in lyrics, use @code{\skip}.
3411 Input for lyrics introduces a syntactical ambiguity:
3418 is interpreted as assigning a string identifier @code{\foo} such that
3419 it contains @code{"bar"}. However, it could also be interpreted as
3420 making or a music identifier @code{\foo} containing the syllable
3421 `bar'. The force the latter interpretation, use
3431 The term @emph{ambitus} denotes a range of pitches for a given voice in
3432 a part of music. It also may denote the pitch range that a musical
3433 instrument is capable of playing. Most musical instruments have their
3434 ambitus standardized (or at least there is agreement upon the minimal
3435 ambitus of a particular type of instrument), such that a composer or
3436 arranger of a piece of music can easily meet the ambitus constraints of
3437 the targeted instrument. However, the ambitus of the human voice
3438 depends on individual physiological state, including education and
3439 training of the voice. Therefore, a singer potentially has to check for
3440 each piece of music if the ambitus of that piece meets his individual
3441 capabilities. This is why the ambitus of a piece may be of particular
3442 value to vocal performers.
3444 The ambitus is typically notated on a per-voice basis at the very
3445 beginning of a piece, e.g. nearby the initial clef or time signature of
3446 each staff. The range is graphically specified by two noteheads, that
3447 represent the minimum and maximum pitch. Some publishers use a textual
3448 notation: they put the range in words in front of the corresponding
3449 staff. Lilypond currently only supports the graphical ambitus notation.
3451 To apply, add the @internalsref{Ambitus_engraver} to the
3452 @internalsref{Voice} context, i.e.
3455 \paper @{ \translator @{

3498 Tablature notation is used for notating music for plucked string
3499 instruments. It notates pitches not by using note heads, but by
3500 indicating on which string and fret a note must be played. LilyPond
3501 offers limited support for tablature.

3573 You can change the tuning of the strings. A string tuning is given as
3574 a Scheme list with one integer number for each string, the number
3575 being the pitch (measured in semitones relative to central C) of an
3576 open string. The numbers specified for @code{stringTuning} are the
3577 numbers of semitones to subtract or add, starting the specified pitch

3645 @subsection Chords mode
3648 Chord mode is a mode where you can input sets of pitches using common
3649 names. It is introduced by the keyword @code{\chords}.
3650 In chords mode, a chord is entered by the root, which is entered
3651 like a common pitch, for example,
3652 @lilypond[fragment,verbatim,quote, relative=1]
3653 \chords { es4. d8 c2 }
3658 Other chords may be entered by suffixing a colon, and introducing a
3659 modifier, and optionally, a number, for example
3661 @lilypond[fragment,verbatim,quote]
3662 \chords { e1:m e1:7 e1:m7 }
3664 The first number following the root is taken to be the `type' of the
3665 chord, thirds are added to the root until it reaches the specified
3666 number, for example.
3667 @lilypond[fragment,verbatim]
3668 \chords { c:3 c:5 c:6 c:7 c:8 c:9 c:10 c:11 }
3671 @cindex root of chord
3672 @cindex additions, in chords
3673 @cindex removals, in chords
3675 More complex chords may also be constructed adding separate steps
3676 to a chord. Additions are added after the number following
3677 the colon, and are separated by dots. For example
3679 @lilypond[verbatim,fragment,quote]
3680 \chords { c:5.6 c:3.7.8 c:3.6.13 }
3682 Chord steps can be altered by suffixing a @code{-} or @code{+} sign
3683 to the number, for example:
3684 @lilypond[verbatim,fragment,quote]
3685 \chords { c:7+ c:5+.3- c:3-.5-.7- }
3687 Removals are specified similarly, and are introduced by a caret. They
3688 must come after the additions.
3689 @lilypond[verbatim,fragment]
3690 \chords { c^3 c:7^5 c:9^3.5 }
3693 Modifiers can be used to change pitches. The following modifiers are
3697 is the minor chord. This modifier lowers the 3rd and (if present) the 7th step.
3699 is the diminished chord. This modifier lowers the 3rd, 5th and (if present)
3702 is the augmented chord. This modifier raises the 5th step.
3704 is the major 7th chord. This modifier raises the 7th step if present.
3706 is the suspended 4th or 2nd. This modifier removes the 3rd
3707 step. Append either @code{2} or @code{4} to add the 2nd or 4th step to
3710 Modifiers can be mixed with additions.

3712 \chords { c:sus4 c:7sus4 c:dim7 c:m6 }
3715 @cindex modifiers, in chords.
3722 Since the unaltered 11 does sound well when combined with the
3723 unaltered 3, the 11 is removed in this case, unless it is added
3724 explicitly). For example,
3725 @lilypond[fragment,verbatim]
3726 \chords { c:13 c:13.11 c:m13 }
3731 An inversion (putting one pitch of the chord on the bottom), as well
3732 as bass notes, can be specified by appending
3733 @code{/}@var{pitch} to the chord.
3734 @lilypond[fragment,verbatim,center]
3735 \chords { c1 c/g c/f }
3739 A bass note can be added instead of transposed out of the chord,
3740 by using @code{/+}@var{pitch}.
3742 @lilypond[fragment,verbatim,center]
3743 \chords { c1 c/+g c/+f }
3746 Chords is a mode similar to @code{\lyrics}, @code{\notes} etc. Most
3747 of the commands continue to work, for example, @code{r} and
3748 @code{\skip} can be used to insert rests and spaces, and
3749 @code{\property} may be used to change various settings.
3755 Each step can only be present in a chord once. The following

3806 The default chord name layout is a system for Jazz music, proposed by

3808 following properties:
3811 @cindex chordNameExceptions
3812 @item chordNameExceptions

3821 This property contains the markup object used for the 7th step, when
3822 it is major. Predefined options are @code{whiteTriangleMarkup} and
3823 @code{blackTriangleMarkup}. See
3824 @inputfileref{input/regression,chord-name-major7.ly} for an example.

3839 @cindex chordRootNamer
3840 @item chordRootNamer
3841 The root of a chord is usually printed as a letter with an optional
3842 alteration. The transformation from pitch to letter is done by this
3843 function. Special note names (for example, the German ``H'' for a
3844 B-chord) can be produced by storing a new function in this property.
3846 @cindex chordNoteNamer
3847 @item chordNoteNamer
3848 The default is to print single pitch, e.g. the bass note, using the
3849 @code{chordRootNamer}. The @code{chordNoteNamer} property can be set
3850 to a specialized function to change this behavior. For example, the
3851 base can be printed in lower case.
3856 There are also two other chord name schemes implemented: an alternate
3857 Jazz chord notation, and a systematic scheme called Banter chords. The
3858 alternate jazz notation is also shown on the chart in @ref{Chord name
3859 chart}. Turning on these styles is described in the input file

4005 which is normally updated automatically for every measure.
4007 Bar numbers can be typeset at regular intervals instead of at the

4122 meant for full bar rests and for entering parts: the rest can expand to
4123 fill a score with rests, or it can be printed as a single multimeasure
4124 rest. This expansion is controlled by the property

4214 The syntax for part combining is

4594 @subsection Custodes
4599 A @emph{custos} (plural: @emph{custodes}; latin word for `guard') is a
4600 symbol that appears at the end of a staff. It anticipates the pitch
4601 of the first note(s) of the following line and thus helps the player
4602 or singer to manage line breaks during performance, thus enhancing
4603 readability of a score.
4605 Custodes were frequently used in music notation until the 17th
4606 century. Nowadays, they have survived only in a few particular forms
4607 of musical notation such as contemporary editions of Gregorian chant
4608 like the @emph{editio vaticana}. There are different custos glyphs
4609 used in different flavours of notational style.
4611 For typesetting custodes, just put a @internalsref{Custos_engraver} into the
4612 @internalsref{Staff} context when declaring the @code{\paper} block,
4613 as shown in the following example.
4619 \consists Custos_engraver
4620 Custos \override #'style = #'mensural
4625 The result looks like this:
4631 \property Staff.Custos \set #'style = #'mensural
4638 \consists Custos_engraver
4645 The custos glyph is selected by the @code{style} property. The styles
4646 supported are @code{vaticana}, @code{medicaea}, @code{hufnagel} and
4647 @code{mensural}. They are demonstrated in the following fragment:
4657 { " " \musicglyph #"custodes-vaticana-u0" }
4661 { " " \musicglyph #"custodes-medicaea-u0" }
4665 { " " \musicglyph #"custodes-hufnagel-u0" }
4669 { " " \musicglyph #"custodes-mensural-u0" }
4678 \remove "Bar_number_engraver"
4682 \remove "Clef_engraver"
4683 \remove "Key_engraver"
4684 \remove "Time_signature_engraver"
4685 \remove "Staff_symbol_engraver"
4686 minimumVerticalExtent = ##f
4692 If the boolean property @code{adjust-if-on-staffline} is set to
4693 @code{#t} (which it is by default), lily typesets slightly different
4694 variants of the custos glyph, depending on whether the custos, is
4695 typeset on or between stafflines. The glyph will
4696 optically fit well into the staff, with the appendage on the right of
4697 the custos always ending at the same vertical position between two
4698 stafflines regardless of the pitch. If you set
4699 @code{adjust-if-on-staffline} to @code{#f}, then
4700 a compromise between both forms is used.
4702 Just like stems can be attached to noteheads in two directions
4703 @emph{up} and @emph{down}, each custos glyph is available with its
4704 appendage pointing either up or down. If the pitch of a custos is
4705 above a selectable position, the appendage will point downwards; if
4706 the pitch is below this position, the appendage will point upwards.
4707 Use property @code{neutral-position} to select this position. By
4708 default, it is set to @code{0}, such that the neutral position is the
4709 center of the staff. Use property @code{neutral-direction} to control
4710 what happens if a custos is typeset on the neutral position itself.
4711 By default, this property is set to @code{-1}, such that the appendage
4712 will point downwards. If set to @code{1}, the appendage will point
4713 upwards. Other values such as @code{0} are reserved for future
4714 extensions and should not be used.
4719 @internalsref{Custos}, @inputfileref{input/test,custos-style.ly} and
4720 @inputfileref{input/regression,custos.ly}.
4724 @subsection Divisiones
4730 A @emph{divisio} (plural: @emph{divisiones}; latin word for
4731 `division') is a staff context symbol that is used to structure
4732 Gregorian music into phrases and sections. The musical meaning of
4733 @emph{divisio minima}, @emph{divisio maior} and @emph{divisio maxima}
4734 can be characterized as short, medium and long pause, somewhat like
4735 @ref{Breath marks}. The @emph{finalis} sign not only marks the end of
4736 a chant, but is also frequently used within a single
4737 antiphonal/responsorial chant to mark the end of each section.
4741 To use divisiones, include the file @code{gregorian-init.ly}. It
4742 contains definitions that you can apply by just inserting
4743 @code{\divisioMinima}, @code{\divisioMaior}, @code{\divisioMaxima},
4744 and @code{\finalis} at proper places in the input. Some editions use
4745 @emph{virgula} or @emph{caesura} instead of divisio minima.
4746 Therefore, @code{gregorian-init.ly} also defines @code{\virgula} and
4750 @lilypondfile[notexidoc]{divisiones.ly}
4754 @internalsref{BreathingSign}, @internalsref{BreathingSignEvent},
4755 @inputfileref{input/test,divisiones.ly}, @ref{Breath marks}.
4758 @subsection Ligatures
4762 @c TODO: Should double check if I recalled things correctly when I wrote
4763 @c down the following paragraph by heart.
4765 In musical terminology, a ligature is a coherent graphical symbol that
4766 represents at least two different notes. Ligatures originally appeared
4767 in the manuscripts of Gregorian chant notation roughly since the 9th
4768 century as an allusion to the accent symbols of greek lyric poetry to
4769 denote ascending or descending sequences of notes. Both, the shape and
4770 the exact meaning of ligatures changed tremendously during the following
4771 centuries: In early notation, ligatures where used for monophonic tunes
4772 (Gregorian chant) and very soon denoted also the way of performance in
4773 the sense of articulation. With upcoming multiphony, the need for a
4774 metric system arised, since multiple voices of a piece have to be
4775 synchronized some way. New notation systems were invented that used
4776 the manifold shapes of ligatures to now denote rhythmical patterns
4777 (e.g. black mensural notation, mannered notation, ars nova). With the
4778 invention of the metric system of the white mensural notation, the need
4779 for ligatures to denote such patterns disappeared. Nevertheless,
4780 ligatures were still in use in the mensural system for a couple of
4781 decades until they finally disappeared during the late 16th / early 17th
4782 century. Still, ligatures have survived in contemporary editions of
4783 Gregorian chant such as the Editio Vaticana from 1905/08.
4787 Syntactically, ligatures are simply enclosed by @code{\[} and
4788 @code{\]}. Some ligature styles (such as Editio Vaticana) may need
4789 additional input syntax specific for this particular type of ligature.
4790 By default, the @internalsref{LigatureBracket} engraver just puts a
4791 square bracket above the ligature.
4793 @lilypond[singleline,verbatim]
4795 \notes \transpose c c' {
4803 To select a specific style of ligatures, a proper ligature engraver
4804 has to be added to the @internalsref{Voice} context, as explained in
4805 the following subsections. Currently, only white mensural ligatures
4806 are supported with certain limitations. Support for Editio Vaticana
4807 will be added in the future.

4817 @cindex Mensural ligatures
4818 @cindex White mensural ligatures
4820 There is limited support for white mensural ligatures. The
4821 implementation is still experimental; it currently may output strange
4822 warnings or even crash in some cases or produce weird results on more
4823 complex ligatures. To engrave white mensural ligatures, in the paper
4824 block the @internalsref{Mensural_ligature_engraver} has to be put into
4825 the @internalsref{Voice} context, and remove the
4826 @internalsref{Ligature_bracket_engraver}:
4832 \remove Ligature_bracket_engraver
4833 \consists Mensural_ligature_engraver
4838 There is no additional input language to describe the shape of a
4839 white mensural ligature. The shape is rather determined solely from
4840 the pitch and duration of the enclosed notes. While this approach may
4841 take a new user a while to get accustomed, it has the great advantage
4842 that the full musical information of the ligature is known internally.
4843 This is not only required for correct MIDI output, but also allows for
4844 automatic transcription of the ligatures.

4905 Gregorian square neumes notation (following the style of the Editio
4906 Vaticana) is under heavy development, but not yet really usable for
4907 production purposes. Core ligatures can already be typeset, but
4908 essential issues for serious typesetting are still under development,
4909 such as (among others) horizontal alignment of multiple ligatures,
4910 lyrics alignment and proper accidentals handling. Still, this section

6276 Unlike most other neumes notation systems, the input language for
6277 neumes does not necessarily reflect directly the typographical
6278 appearance, but is designed to solely focuse on musical meaning. For
6279 example, @code{\[ a \pes b \flexa g \]} produces a Torculus consisting
6280 of three Punctum heads, while @code{\[ a \flexa g \pes b \]} produces
6281 a torculus with a curved flexa shape and only a single Punctum head.
6282 There is no command to explicitly typeset the curved flexa shape; the
6283 decision of when to typeset a curved flexa shape is purely taken from
6284 the musical input. The idea of this approach is to separate the
6285 musical aspects of the input from the notation style of the output.
6286 This way, the same input can be reused to typeset the same music in a
6287 different style of Gregorian chant notation such as Hufnagel (also
6288 known as German gothic neumes) or Medicaea (kind of a very simple
6289 forerunner of the Editio Vaticana). As soon as Hufnagel ligature
6290 engraver and Medicaea ligature engraver will have been implemented, it
6291 will be as simple as replacing the ligature engraver in the
6292 @internalsref{Voice} context to get the desired notation style from

6299 ligature. The third column shows the code fragment that produces this

6533 @c TODO: musicological blurb about FB
6537 LilyPond has limited support for figured bass:
6539 @lilypond[verbatim,fragment]
6541 \context Voice \notes { \clef bass dis4 c d ais}
6542 \context FiguredBass
6544 < 6 >4 < 7 >8 < 6+ [_!] >
6550 The support for figured bass consists of two parts: there is an input
6551 mode, introduced by @code{\figures}, where you can enter bass figures
6552 as numbers, and there is a context called @internalsref{FiguredBass}
6553 that takes care of making @internalsref{BassFigure} objects.
6555 In figures input mode, a group of bass figures is delimited by
6556 @code{<} and @code{>}. The duration is entered after the @code{>}.
6561 \context FiguredBass
6565 Accidentals are added when you append @code{-}, @code{!} and @code{+}
6572 \context FiguredBass
6573 \figures { <4- 6+ 7!> }
6576 Spaces or dashes may be inserted by using @code{_}. Brackets are
6577 introduced with @code{[} and @code{]}.
6583 \context FiguredBass
6584 \figures { < [4 6] 8 [_! 12]> }
6587 Although the support for figured bass may superficially resemble chord
6588 support, it works much simpler. The @code{\figures} mode simply
6589 stores the numbers , and @internalsref{FiguredBass} context prints
6590 them as entered. There is no conversion to pitches, and no
6591 realizations of the bass are played in the MIDI file.
6593 Internally, the code produces markup texts. You can use any of the
6594 markup text properties to override formatting. For example, the
6595 vertical spacing of the figures may be set with @code{baseline-skip}.

6607 @node Contemporary notation
6608 @section Contemporary notation
6610 In the 20th century, composers have greatly expanded the musical
6611 vocabulary. With this expansion, many innovations in musical notation
6612 have been tried. For a comprehensive overview, refer to @cite{Stone
6613 1980} (see @ref{Literature}). In general, the use of new, innovative
6614 notation makes a piece harder to understand and perform and its use
6615 should therefore be avoided if possible. For this reason, support for
6616 contemporary notation in LilyPond is limited.
6625 @subsection Clusters
6629 In musical terminology, a @emph{cluster} denotes a range of
6630 simultaneously sounding pitches that may change over time. The set of
6631 available pitches to apply usually depends on the accoustic source.
6632 Thus, in piano music, a cluster typically consists of a continous range
6633 of the semitones as provided by the piano's fixed set of a chromatic
6634 scale. In choral music, each singer of the choir typically may sing an
6635 arbitrary pitch within the cluster's range that is not bound to any
6636 diatonic, chromatic or other scale. In electronic music, a cluster
6637 (theoretically) may even cover a continuous range of pitches, thus
6638 resulting in coloured noise, such as pink noise.
6640 Clusters can be denoted in the context of ordinary staff notation by
6641 engraving simple geometrical shapes that replace ordinary notation of
6642 notes. Ordinary notes as musical events specify starting time and
6643 duration of pitches; however, the duration of a note is expressed by the
6644 shape of the note head rather than by the horizontal graphical extent of
6645 the note symbol. In contrast, the shape of a cluster geometrically
6646 describes the development of a range of pitches (vertical extent) over
6647 time (horizontal extent). Still, the geometrical shape of a cluster
6648 covers the area in wich any single pitch contained in the cluster would
6649 be notated as an ordinary note. From this point of view, it is
6650 reasonable to specify a cluster as the envelope of a set of notes.
6654 A cluster is engraved as the envelope of a set of
6655 cluster-notes. Cluster notes are created by applying the function
6656 @code{notes-to-clusters} to a sequence of chords, eg.
6658 @lilypond[relative 1,verbatim]
6659 \apply #notes-to-clusters { <<c e >> <<b f'>> }
6662 The following example (from
6663 @inputfileref{input/regression,cluster.ly}) shows what the result
6666 @lilypondfile[notexidoc]{cluster.ly}
6668 By default, @internalsref{Cluster_engraver} is in the
6669 @internalsref{Voice} context. This allows putting ordinary notes and
6670 clusters together in the same staff, even simultaneously. In such a
6671 case no attempt is made to automatically avoid collisions between
6672 ordinary notes and clusters.
6676 @internalsref{ClusterSpanner}, @internalsref{ClusterSpannerBeacon},
6677 @inputfileref{input/regression,cluster.ly},
6678 @internalsref{Cluster_engraver}, @internalsref{ClusterNoteEvent}.
6682 Music expressions like @code{< @{ g8 e8 @} a4 >} are not printed
6683 accurately. Use @code{<<g a>>8 <<e a>>8} instead.
6688 @subsection Fermatas
6694 Contemporary music notation frequently uses special fermata symbols to
6695 indicate fermatas of differing lengths.
6699 The following are supported
6701 @lilypond[singleline]
6703 < \addlyrics \notes {
6723 \context Lyrics \lyrics {
6724 "shortfermata" "fermata" "longfermata" "verylongfermata"
6729 See @ref{Articulations} for general instructions how to apply scripts
6730 such as fermatas to a @code{\notes@{@}} block.
6733 @section Tuning output
6735 There are situations where default layout decisions are not
6736 sufficient. In this section we discuss ways to override these
6739 Formatting is internally done by manipulating so called objects
6740 (graphic objects). Each object carries with it a set of properties
6741 (object or layout properties) specific to that object. For example, a
6742 stem object has properties that specify its direction, length and
6745 The most direct way of tuning the output is by altering the values of
6746 these properties. There are two ways of doing that: first, you can
6747 temporarily change the definition of one type of object, thus
6748 affecting a whole set of objects. Second, you can select one specific
6749 object, and set a layout property in that object.
6751 Do not confuse layout properties with translation
6752 properties. Translation properties always use a mixed caps style
6753 naming, and are manipulated using @code{\property}
6755 \property Context.propertyName = @var{value}
6757 Layout properties are use Scheme style variable naming, i.e. lower
6758 case words separated with dashes. They are symbols, and should always
6759 be quoted using @code{#'}. For example, this could be an imaginary
6760 layout property name:
6762 #'layout-property-name
6767 * Constructing a tweak::
6776 @node Tuning objects
6777 @subsection Tuning objects
6779 @cindex object description
6781 The definition of an object is a list of default object
6782 properties. For example, the definition of the Stem object (available
6783 in @file{scm/define-grobs.scm}), includes the following definitions
6784 for @internalsref{Stem}
6788 (beamed-lengths . (0.0 2.5 2.0 1.5))
6789 (Y-extent-callback . ,Stem::height)
6794 Adding variables on top of this existing definition overrides the
6795 system default, and alters the resulting appearance of the layout
6801 Changing a variable for only one object is commonly achieved with
6805 \once \property @var{context}.@var{objectname}
6806 \override @var{symbol} = @var{value}
6808 Here @var{symbol} is a Scheme expression of symbol type, @var{context}
6809 and @var{objectname} is a string and @var{value} is a Scheme expression.
6810 This command applies a setting only during one moment in the score.
6812 In the following example, only one @internalsref{Stem} object is
6813 changed from its original setting:
6815 @lilypond[verbatim, fragment, relative=1]
6817 \once \property Voice.Stem \set #'thickness = #4
6821 @cindex @code{\once}
6823 For changing more objects, the same command, without @code{\once} can
6826 \property @var{context}.@var{objectname} \override @var{symbol} = @var{value}
6828 This command adds @code{@var{symbol} = @var{value}} to the definition
6829 of @var{objectname} in the context @var{context}, and this definition
6830 stays in place until it is removed.
6832 An existing definition may be removed by the following command
6835 \property @var{context}.@var{objectname} \revert @var{symbol}
6838 All @code{\override} and @code{\revert} commands should be balanced.
6839 The @code{\set} shorthand performs a revert followed by an override,
6840 and is often more convenient to use
6843 \property @var{context}.@var{objectname} \set @var{symbol} = @var{value}
6847 @lilypond[verbatim,quote]
6848 c'4 \property Voice.Stem \override #'thickness = #4.0
6850 c'4 \property Voice.Stem \revert #'thickness
6854 The following example gives exactly the same result as the previous
6855 one (assuming the system default for stem thickness is 1.3).
6857 @lilypond[verbatim,quote]
6858 c'4 \property Voice.Stem \set #'thickness = #4.0
6860 c'4 \property Voice.Stem \set #'thickness = #1.3
6864 Reverting a setting which was not set in the first place has no
6865 effect. However, if the setting was set as a system default, this may
6866 remove the default value, and this may give surprising results,
6867 including crashes. In other words, @code{\override} and
6868 @code{\revert} must be carefully balanced. The following are examples
6869 of correct nesting of @code{\override}, @code{\set}, @code{\revert}.
6873 A clumsy but correct form:
6875 \override \revert \override \revert \override \revert
6879 Shorter version of the same:
6881 \override \set \set \revert
6885 A short form, using only @code{\set}. This requires you to know the
6888 \set \set \set \set @var{to default value}
6892 If there is no default (i.e. by default, the object property is unset),
6895 \set \set \set \revert
6899 For the digirati, the object description is an Scheme association
6900 list. Since a Scheme list is a singly linked list, we can treat it as
6901 a stack, and @code{\override} and @code{\revert} are push and pop
6902 operations. The association list is stored in a normal context
6905 \property Voice.NoteHead = #'()
6907 will effectively erase @internalsref{NoteHead}s from the current
6908 @internalsref{Voice}. However, this mechanism is not guaranteed to
6909 work, and may cause crashes or other anomalous behavior.
6913 @internalsref{OverrideProperty}, @internalsref{RevertProperty},
6914 @internalsref{PropertySet}, @internalsref{backend properties},
6915 @internalsref{All layout objects}.
6920 The backend is not very strict in type-checking object properties.
6921 Cyclic references in @var{value} cause hangs and/or crashes.
6922 Similarly, reverting properties that are system defaults may also lead

6933 @cindex @code{\override}
6935 @cindex internal documentation
6939 Three pieces of information are required to use @code{\override} and
6940 @code{\set}: the name of the layout object, the context and the name
6941 of the property. We demonstrate how to glean this information from
6942 the notation manual and the generated documentation.
6944 The generated documentation is a set of HTML pages which should be
6945 included if you installed a binary distribution, typically in
6946 @file{/usr/share/doc/lilypond}. They are also available on the web:
6947 go to the @uref{http://lilypond.org,LilyPond website}, click
6948 ``Documentation'', and then ``Program reference'' on the side bar. It
6949 is advisable to bookmark either the local HTML files if possible. They
6950 will load faster than the ones on the web. If you use the version
6951 from the web, you must check whether the documentation matches the
6952 program version: the documentation is generated from the definitions
6953 that the program uses, and therefore it is strongly tied to the
6957 @c [TODO: revise for new site.]
6959 Suppose we want to move the fingering indication in the fragment below
6961 @lilypond[relative=2,verbatim]
6967 If you visit the documentation of @code{Fingering} (in @ref{Fingering
6968 instructions}), you will notice that it says
6973 @internalsref{FingerEvent} and @internalsref{Fingering}.
6977 In other words, the fingerings once entered, are internally stored as
6978 @code{FingerEvent} music objects. When printed, a @code{Fingering}
6979 layout object is created for every @code{FingerEvent}.
6981 The Fingering object has a number of different functions, and each of
6982 those is captured in an interface. when we look up
6983 @internalsref{Fingering} in the generated documentation.
6987 The @code{Fingering} object has a fixed size
6988 (@internalsref{item-interface}), the symbol is a piece of text
6989 (@internalsref{text-interface}), whose font can be set
6990 (@internalsref{font-interface}). It is centered horizontally
6991 (@internalsref{self-alignment-interface}), it is placed next to other
6992 objects (@internalsref{side-position-interface}) vertically, and its
6993 placement is coordinated with other scripts
6994 (@internalsref{text-script-interface}). It also has the standard
6995 @internalsref{grob-interface} (grob stands for Graphical object)
6997 @cindex graphical object
6998 @cindex layout object
6999 @cindex object, layout
7000 with all the variables that come with
7001 it. Finally, it denotes a fingering instruction, so it has
7002 @internalsref{finger-interface}.
7004 For the vertical placement, we have to look under
7005 @code{side-position-interface}.
7007 @code{side-position-interface}
7009 Position a victim object (this one) next to other objects (the
7010 support). In this case, the direction signifies where to put the
7011 victim object relative to the support (left or right, up or down?)
7013 below this description, the variable @code{padding} is described as
7017 (dimension, in staff space)
7019 add this much extra space between objects that are next to each
7020 other. Default value: @code{0.6}
7024 By increasing the value of @code{padding}, we can move away the
7025 fingering. The following command inserts 3 staff spaces of white
7026 between the note and the fingering
7028 \once \property Voice.Fingering \set #'padding = #3
7031 Inserting this command before the Fingering object is created,
7032 i.e. before @code{c2}, yields the following result.
7034 @lilypond[relative=2,fragment,verbatim]
7035 \once \property Voice.Fingering
7042 The context name @code{Voice} in the example above can be determined
7043 as follows. In the documentation for @internalsref{Fingering}, it says
7045 Fingering grobs are created by: @internalsref{Fingering_engraver}
7048 Clicking @code{Fingering_engraver} shows the documentation of
7049 the module responsible for interpreting the fingering instructions and
7050 translating them to a @code{Fingering} object. Such a module is called
7051 an @emph{engraver}. The documentation of the @code{Fingering_engraver}
7054 Fingering_engraver is part of contexts: Voice
7056 so tuning the settings for Fingering should be done with
7058 \property Voice.Fingering \set @dots{}
7061 Of course, the tweak may also done in a larger context than
7062 @code{Voice}, for example, @internalsref{Staff} or
7063 @internalsref{Score}.
7065 The internals document also contains alphabetical lists of
7066 @internalsref{All contexts}, @internalsref{All layout objects} and
7067 @internalsref{All music types}, so you can also find which objects to
7068 tweak by browsing the internals document.
7072 @subsection Applyoutput
7074 The most versatile way of tuning an object is @code{\applyoutput}. Its
7077 \applyoutput @var{proc}
7081 where @var{proc} is a Scheme function, taking four arguments.
7083 When interpreted, the function @var{proc} is called for every layout object found
7084 in the context, with the following arguments:
7086 @item the layout object itself
7087 @item the context where the layout object was created
7088 @item the context where @code{\applyoutput} is processed.
7091 In addition, the cause of the layout object, i.e. the music
7092 expression or object that was responsible for creating it, is in the
7093 object property @code{cause}. For example, for a note head, this is a
7094 @internalsref{NoteHead} event, and for a @internalsref{Stem} object,
7095 this is a @internalsref{NoteHead} object.
7098 @node Outputproperty
7099 @subsection Outputproperty
7101 @cindex @code{\outputproperty}
7103 Another way of tuning objects is the more arcane @code{\outputproperty}
7104 feature. The syntax is as follows:
7106 \outputproperty @var{predicate} @var{symbol} = @var{value}
7108 Here @code{predicate} is a Scheme function taking an object argument, and
7109 returning a boolean. This statement is processed by the
7110 @code{Output_property_engraver}. It instructs the engraver to feed all
7111 objects that it sees to @var{predicate}. Whenever the predicate returns
7112 true, the object property @var{symbol} will be set to @var{value}.
7114 You will need to combine this statement with @code{\context} to select
7115 the appropriate context to apply this to.
7116 @inputfileref{input/regression,output-property.ly} shows an example of
7117 the use of @code{\outputproperty}.
7121 This command is slated for removal. Please use the
7122 @code{\applyoutput} command, see @ref{Applyoutput}.
7125 @node Font selection
7126 @subsection Font selection
7128 The most common thing to change about the appearance of fonts is their
7129 size. The font size of any context can be easily changed by setting
7130 the @code{fontSize} property for that context. Its value is an
7131 integer: negative numbers make the font smaller, positive numbers
7132 larger. An example is given below.
7134 @lilypond[fragment,relative=1,verbatim,quote]
7135 c4 c4 \property Voice.fontSize = #-1
7138 This command will set @code{font-relative-size} (see below), and does
7139 not change the size of variable symbols, such as beams or slurs.
7142 One of the uses of @code{fontSize} is to get smaller symbol for cue
7143 notes. An elaborate example of those is in
7144 @inputfileref{input/test,cue-notes.ly}.
7146 @cindex magnification
7148 The size of the font may be scaled with the object property
7149 @code{font-magnification}. For example, @code{2.0} blows up all
7150 letters by a factor 2 in both directions.
7159 The font used for printing a object can be selected by setting
7160 @code{font-name}, e.g.
7162 \property Staff.TimeSignature
7163 \set #'font-name = #"cmr17"
7167 Any font can be used, as long as it is available to @TeX{}. Possible
7168 fonts include foreign fonts or fonts that do not belong to the
7169 Computer Modern font family.
7171 Font selection for the standard fonts, @TeX{}'s Computer Modern fonts,
7172 can also be adjusted with a more fine-grained mechanism. By setting
7173 the object properties described below, you can select a different font.
7174 All three mechanisms work for every object that supports
7175 @code{font-interface}.
7179 A symbol indicating the general class of the typeface. Supported are
7180 @code{roman} (Computer Modern), @code{braces} (for piano staff
7181 braces), @code{music} (the standard music font, including ancient
7182 glyphs), @code{dynamic} (for dynamic signs) and @code{typewriter}.
7185 A symbol indicating the shape of the font, there are typically several
7186 font shapes available for each font family. Choices are @code{italic},
7187 @code{caps} and @code{upright}
7190 A symbol indicating the series of the font. There are typically several
7191 font series for each font family and shape. Choices are @code{medium}
7194 @item font-relative-size
7195 A number indicating the size relative the standard size. For example,
7196 with 20pt staff height, relative size -1 corresponds to 16pt staff
7197 height, and relative size +1 corresponds to 23 pt staff height.
7199 There are small differences in design between fonts designed for
7200 different sizes, hence @code{font-relative-size} is preferred over
7201 @code{font-magnification} for changing font sizes.
7204 @item font-design-size
7205 A number indicating the design size of the font.
7207 This is a feature of the Computer Modern Font: each point size has a
7208 slightly different design. Smaller design sizes are relatively wider,
7209 which enhances readability.
7212 For any of these properties, the value @code{*} (i.e. the symbol
7213 @code{*}, entered as @code{#'*}), acts as a wildcard. This can be used
7214 to override default setting, which are always present. For example:
7216 \property Lyrics . LyricText \override #'font-series = #'bold
7217 \property Lyrics . LyricText \override #'font-family = #'typewriter
7218 \property Lyrics . LyricText \override #'font-shape = #'*
7221 @cindex @code{font-style}
7225 The following commands set @code{fontSize} for the current voice.
7227 @cindex @code{\tiny}
7229 @cindex @code{\small}
7231 @cindex @code{\normalsize}
7236 Relative size is not linked to any real size.
7238 There is no style sheet provided for other fonts besides the @TeX{}
7239 family, and the style sheet cannot be modified easily.

7247 @subsection Text markup
7252 @cindex typeset text
7254 LilyPond has an internal mechanism to typeset texts. You can access it
7255 with the keyword @code{\markup}. Within markup mode, you can enter texts
7256 similar to lyrics: simply enter them, surrounded by spaces.
7259 @lilypond[verbatim,fragment,relative=1]
7260 c1^\markup { hello }
7261 c1_\markup { hi there }
7262 c1^\markup { hi \bold there, is \italic anyone home? }
7265 @cindex font switching
7267 The markup in the example demonstrates font switching commands. The
7268 command @code{\bold} and @code{\italic} only apply to the first
7269 following word; enclose a set of texts with braces to apply a command
7272 \markup @{ \bold @{ hi there @} @}
7276 For clarity, you can also do this for single arguments, e.g.
7278 \markup @{ is \italic @{ anyone @} home @}
7281 @cindex font size, texts
7283 The following size commands set abolute sizes
7285 @cindex @code{\teeny}
7286 @cindex @code{\tiny}
7287 @cindex @code{\small}
7288 @cindex @code{\large}
7289 @cindex @code{\huge}
7299 You can also make letter larger or smaller relative to their neighbors,
7300 with the commands @code{\larger} and @code{\smaller}.
7304 @cindex font style, for texts
7305 @cindex @code{\bold}
7306 @cindex @code{\dynamic}
7307 @cindex @code{\number}
7308 @cindex @code{\italic}
7310 The following font change commands are defined:
7313 This changes to the font used for dynamic signs. This font does not
7314 contain all characters of the alphabet, so when producing ``piu f'',
7315 the ``piu'' should be done in a different font.
7319 This changes to the font used for time signatures. It only contains
7320 numbers and a few punctuation marks.
7322 Changes @code{font-shape} to @code{italic}
7324 Changes @code{font-series} to @code{bold}
7327 @cindex raising text
7328 @cindex lowering text
7330 @cindex translating text
7333 @cindex @code{\super}
7335 Raising and lowering texts can be done with @code{\super} and
7338 @lilypond[verbatim,fragment,relative=1]
7339 c1^\markup { E "=" mc \super "2" }
7342 @cindex @code{\raise}
7344 If you want to give an explicit amount for lowering or raising, use
7345 @code{\raise}. This command takes a Scheme valued first argument, and
7346 a markup object as second argument
7348 @lilypond[verbatim,fragment,relative=1,quote]
7349 c1^\markup { C \small \raise #1.0 \bold { "9/7+" }}
7351 The argument to @code{\raise} is the vertical displacement amount,
7352 measured in (global) staff spaces.
7354 Other commands taking single arguments include
7357 @item \bracket, \hbracket
7358 Bracket the argument markup with normal and horizontal brackets
7362 @cindex @code{\musicglyph}
7363 This is converted to a musical symbol, e.g. @code{\musicglyph
7364 #"accidentals-0"} will select the natural sign from the music font.
7365 See @ref{The Feta font} for a complete listing of the possible glyphs.
7367 This produces a single character, e.g. @code{\char #65} produces the
7370 @item \note @var{log} @var{dots} @var{dir}
7371 @cindex @code{\note}
7373 This produces a note with a stem pointing in @var{dir} direction, with
7374 duration log @var{log} and @var{dots} augmentation dots. The duration
7375 log is the negative 2-logarithm of the duration denominator. For
7376 example, a quarter note has log 2, an eighth note 3 and a breve has
7379 @item \hspace #@var{amount}
7380 @cindex @code{\hspace}
7381 This produces a invisible object taking horizontal space.
7383 \markup @{ A \hspace #2.0 B @}
7385 will put extra space between A and B, on top of the space that is
7386 normally inserted before elements on a line.
7388 @item \fontsize #@var{size}
7389 @cindex @code{\fontsize}
7390 This sets the relative font size, eg.
7392 A \fontsize #2 @{ B C @} D
7396 This will enlarge the B and the C by two steps.
7397 @item \translate #(cons @var{x} @var{y})
7399 This translates an object. Its first argument is a cons of numbers
7401 A \translate #(cons 2 -3) @{ B C @} D
7403 This moves `B C' 2 spaces to the right, and 3 down.
7405 @item \magnify #@var{mag}
7406 @cindex @code{\magnify}
7407 This sets the font magnification for the its argument. In the following
7408 example, the middle A will be 10% larger.
7410 A \magnify #1.1 @{ A @} A
7414 @item \override #(@var{key} . @var{value})
7415 @cindex @code{\override}
7416 This overrides a formatting property for its argument. The argument
7417 should be a key/value pair, e.g.
7419 m \override #'(font-family . math) m m
7423 In markup mode you can compose expressions, similar to mathematical
7424 expressions, XML documents and music expressions. The braces group
7425 notes into horizontal lines. Other types of lists also exist: you can
7426 stack expressions grouped with @code{<<}, and @code{>>} vertically with
7427 the command @code{\column}. Similarly, @code{\center} aligns texts by
7430 @lilypond[verbatim,fragment,relative=1]
7431 c1^\markup { \column << a bbbb c >> }
7432 c1^\markup { \center << a bbbb c >> }
7433 c1^\markup { \line << a b c >> }
7436 The markup mechanism is extensible. Refer to
7437 @file{scm/new-markup.scm} for more information on extending the markup
7444 @internalsref{Markup functions}, @file{scm/new-markup.scm}
7451 Text layout is ultimately done by @TeX{}, which does kerning of
7452 letters. LilyPond does not account for kerning, so texts will be
7453 spaced slightly too wide.
7455 Syntax errors for markup mode are confusing.
7459 @section Global layout
7461 The global layout determined by three factors: the page layout, the
7462 line breaks and the spacing. These all influence each other. The
7463 choice of spacing determines how densely each system of music is set,
7464 which influences where line breaks breaks are chosen, and thus
7465 ultimately how many pages a piece of music takes. In this section, the
7466 algorithm for spacing music is explained, and how spacing can be
7469 Globally spoken, this procedure happens in three steps: first,
7470 flexible distances (``springs'') are chosen, based on durations. All
7471 possible line breaking combination are tried, and the one with the
7472 best results---a layout that has uniform density and requires as
7473 little stretching or cramping as possible---is chosen. When the score
7474 is processed by @TeX{}, each page is filled with systems, and page breaks
7475 are chosen whenever the page gets full.
7480 * Vertical spacing::
7481 * Horizontal spacing::
7488 @node Vertical spacing
7489 @subsection Vertical spacing
7491 @cindex vertical spacing
7492 @cindex distance between staves
7493 @cindex staff distance
7494 @cindex between staves, distance
7495 @cindex staffs per page
7498 The height of each system is determined automatically by lilypond, to
7499 keep systems from bumping into each other, some minimum distances are
7500 set. By changing these, you can put staves closer together, and thus
7501 put more systems onto one page.
7503 Normally staves are stacked vertically. To make
7504 staves maintain a distance, their vertical size is padded. This is
7505 done with the property @code{minimumVerticalExtent}. It takes a pair
7506 of numbers, so if you want to make it smaller from its, then you could
7509 \property Staff.minimumVerticalExtent = #'(-4 . 4)
7511 This sets the vertical size of the current staff to 4 staff-space on
7512 either side of the center staff line. The argument of
7513 @code{minimumVerticalExtent} is interpreted as an interval, where the
7514 center line is the 0, so the first number is generally negative. The
7515 staff can be made larger at the bottom by setting it to @code{(-6
7518 The piano staves are handled a little differently: to make cross-staff
7519 beaming work correctly, it necessary that the distance between staves
7520 is fixed beforehand. This is also done with a
7521 @internalsref{VerticalAlignment} object, created in
7522 @internalsref{PianoStaff}. In this object the distance between the
7523 staves is fixed by setting @code{forced-distance}. If you want to
7524 override this, use a @code{\translator} block as follows:
7528 VerticalAlignment \override #'forced-distance = #9
7531 This would bring the staves together at a distance of 9 staff spaces,
7532 measured from the center line of each staff.
7536 Vertical aligment of staves is handled by the
7537 @internalsref{VerticalAlignment} object.
7541 @node Horizontal spacing
7542 @subsection Horizontal Spacing
7544 The spacing engine translates differences in durations into
7545 stretchable distances (``springs'') of differing lengths. Longer
7546 durations get more space, shorter durations get less. The shortest
7547 durations get a fixed amount of space (which is controlled by
7548 @code{shortest-duration-space} in the @internalsref{SpacingSpanner}
7549 object). The longer the duration, the more space it gets: doubling a
7550 duration adds a fixed amount (this amount is controlled by
7551 @code{spacing-increment}) of space to the note.
7553 For example, the following piece contains lots of half, quarter and
7554 8th notes, the eighth note is followed by 1 note head width (NHW).
7555 The quarter note is followed by 2 NHW, the half by 3 NHW, etc.
7556 @lilypond[fragment, verbatim, relative=1] c2 c4. c8 c4. c8 c4. c8 c8
7560 Normally, @code{shortest-duration-space} is set to 1.2, which is the
7561 width of a note head, and @code{shortest-duration-space} is set to
7562 2.0, meaning that the shortest note gets 2 NHW (2 times
7563 @code{shortest-duration-space}) of space. For normal notes, this space
7564 is always counted from the left edge of the symbol, so the shortest
7565 notes are generally followed by one NHW of space.
7567 If one would follow the above procedure exactly, then adding a single
7568 32th note to a score that uses 8th and 16th notes, would widen up the
7569 entire score a lot. The shortest note is no longer a 16th, but a 32nd,
7570 thus adding 2 noteheads of space to every note. To prevent this, the
7571 shortest duration for spacing is not the shortest note in the score,
7572 but the most commonly found shortest note. Notes that are even
7573 shorter this are followed by a space that is proportonial to their
7574 duration relative to the common shortest note. So if we were to add
7575 only a few 16th notes to the example above, they would be followed by
7578 @lilypond[fragment, verbatim, relative=2]
7579 c2 c4. c8 c4. c16-[ c-] c4. c8 c8 c8 c4 c4 c4
7582 The most common shortest duration is determined as follows: in every
7583 measure, the shortest duration is determined. The most common short
7584 duration, is taken as the basis for the spacing, with the stipulation
7585 that this shortest duration should always be equal to or shorter than
7586 1/8th note. The shortest duration is printed when you run lilypond
7587 with @code{--verbose}. These durations may also be customized. If you
7588 set the @code{common-shortest-duration} in
7589 @internalsref{SpacingSpanner}, then this sets the base duration for
7590 spacing. The maximum duration for this base (normally 1/8th), is set
7591 through @code{base-shortest-duration}.
7593 @cindex @code{common-shortest-duration}
7594 @cindex @code{base-shortest-duration}
7595 @cindex @code{stem-spacing-correction}
7596 @cindex @code{spacing}
7598 In the introduction it was explained that stem directions influence
7599 spacing. This is controlled with @code{stem-spacing-correction}
7600 property in @internalsref{NoteSpacing}, which are generated for every
7601 @internalsref{Voice} context. The @code{StaffSpacing} object
7602 (generated at @internalsref{Staff} context) contains the same property
7603 for controlling the stem/barline spacing. The following example
7604 shows these corrections, once with default settings, and once with
7605 exaggerated corrections.
7611 \property Staff.NoteSpacing \override #'stem-spacing-correction
7613 \property Staff.StaffSpacing \override #'stem-spacing-correction
7618 \paper { raggedright = ##t } }
7621 @cindex SpacingSpanner, overriding properties
7623 Properties of the @internalsref{SpacingSpanner} must be overridden
7624 from the @code{\paper} block, since the @internalsref{SpacingSpanner}
7625 is created before any @code{\property} statements are interpreted.
7627 \paper @{ \translator @{
7629 SpacingSpanner \override #'spacing-increment = #3.0
7636 @internalsref{SpacingSpanner}, @internalsref{NoteSpacing},
7637 @internalsref{StaffSpacing}, @internalsref{SeparationItem},
7638 @internalsref{SeparatingGroupSpanner}.
7642 Spacing is determined on a score wide basis. If you have a score that
7643 changes its character (measured in durations) halfway during the
7644 score, the part containing the longer durations will be spaced too
7647 There is no convenient mechanism to manually override spacing.
7652 @subsection Font size
7653 @cindex font size, setting
7654 @cindex staff size, setting
7655 @cindex @code{paper} file
7657 The Feta font provides musical symbols at seven different sizes.
7658 These fonts are 11 point, 13 point, 16 point, 20 point, 23 point, and
7659 26 point. The point size of a font is the height of the corresponding
7660 staff (excluding line thicknesses).
7662 Definitions for these sizes are the files @file{paperSZ.ly}, where
7663 @code{SZ} is one of 11, 13, 16, 20, 23 and 26. If you include any
7664 of these files, the variables @code{paperEleven},
7665 @code{paperThirteen}, @code{paperSixteen},
7666 @code{paperTwenty}, @code{paperTwentythree}, and @code{paperTwentysix}
7667 are defined respectively. The default @code{\paper} block is also
7668 set. These files should be imported at toplevel, i.e.
7670 \include "paper26.ly"
7674 The default font size settings for each staff heights are generated
7675 from the 20pt style sheet. For more details, see the file
7676 @file{scm/font.scm}.
7681 @subsection Line breaking
7684 @cindex breaking lines
7686 Line breaks are normally computed automatically. They are chosen such
7687 that lines look neither cramped nor loose, and that consecutive lines
7688 have similar density.
7690 Occasionally you might want to override the automatic breaks; you can
7691 do this by specifying @code{\break}. This will force a line break at
7692 this point. Line breaks can only occur at places where there are bar
7693 lines. If you want to have a line break where there is no bar line,
7694 you can force an invisible bar line by entering @code{\bar
7695 ""}. Similarly, @code{\noBreak} forbids a line break at a
7699 @cindex regular line breaks
7700 @cindex four bar music.
7702 For linebreaks at regular intervals use @code{\break} separated by
7703 skips and repeated with @code{\repeat}:
7705 < \repeat unfold 7 @{ s1 * 4 \break @}
7706 @emph{the real music}
7711 This makes the following 28 measures (assuming 4/4 time) be broken every
7716 @internalsref{BreakEvent}
7720 @subsection Page layout
7723 @cindex breaking pages
7725 @cindex @code{indent}
7726 @cindex @code{linewidth}
7728 The most basic settings influencing the spacing are @code{indent} and
7729 @code{linewidth}. They are set in the @code{\paper} block. They
7730 control the indentation of the first line of music, and the lengths of
7733 If @code{raggedright} is set to true in the @code{\paper}
7734 block, then the lines are justified at their natural length. This
7735 useful for short fragments, and for checking how tight the natural
7739 @cindex vertical spacing
7741 The page layout process happens outside the LilyPond formatting
7742 engine: variables controlling page layout are passed to the output,
7743 and are further interpreted by @code{ly2dvi}. @code{ly2dvi} responds
7744 to the following variables in the @code{\paper} block. The variable
7745 @code{textheight} sets the total height of the music on each page.
7746 The spacing between systems is controlled with @code{interscoreline},
7747 its default is 16pt. The distance between the score lines will
7748 stretch in order to fill the full page @code{interscorelinefill} is
7749 set to a positive number. In that case @code{interscoreline}
7750 specifies the minimum spacing.
7752 @cindex @code{textheight}
7753 @cindex @code{interscoreline}
7754 @cindex @code{interscorelinefill}
7756 If the variable @code{lastpagefill} is defined,
7757 @c fixme: this should only be done if lastpagefill == #t
7758 systems are evenly distributed vertically on the last page. This
7759 might produce ugly results in case there are not enough systems on the
7760 last page. The @command{lilypond-book} command ignores
7761 @code{lastpagefill}. See @ref{lilypond-book manual} for more
7764 @cindex @code{lastpagefill}
7766 Page breaks are normally computed by @TeX{}, so they are not under
7767 direct control of LilyPond. However, you can insert a commands into
7768 the @file{.tex} output to instruct @TeX{} where to break pages. This
7769 is done by setting the @code{between-systems-strings} on the
7770 @internalsref{NonMusicalPaperColumn} where the system is broken.
7771 An example is shown in @inputfileref{input/regression,between-systems.ly}.
7772 The predefined command @code{\newpage} also does this.
7776 @cindex @code{papersize}
7778 To change the paper size, you must first set the
7779 @code{papersize} paper variable variable. Set it to
7780 the strings @code{a4}, @code{letter}, or @code{legal}. After this
7781 specification, you must set the font as described above. If you want
7782 the default font, then use the 20 point font.
7785 \paper@{ papersize = "a4" @}
7786 \include "paper16.ly"
7789 The file @code{paper16.ly} will now include a file named @file{a4.ly}, which
7790 will set the paper variables @code{hsize} and @code{vsize} (used by
7791 Lilypond and @code{ly2dvi})
7796 @cindex @code{\newpage}

7808 LilyPond has no concept of page layout, which makes it difficult to
7809 reliably choose page breaks in longer pieces.
7818 Entered music can also be converted to MIDI output. The performance
7819 is good enough for proof-hearing the music for errors.
7821 Ties, dynamics and tempo changes are interpreted. Dynamic marks,
7822 crescendi and decrescendi translate into MIDI volume levels. Dynamic
7823 marks translate to a fixed fraction of the available MIDI volume
7824 range, crescendi and decrescendi make the volume vary linearly between
7825 their two extremities. The fractions be adjusted by
7826 @code{dynamicAbsoluteVolumeFunction} in @internalsref{Voice} context.
7827 For each type of MIDI instrument, a volume range can be defined. This
7828 gives a basic equalizer control, which can enhance the quality of
7829 the MIDI output remarkably. The equalizer can be controlled by
7830 setting @code{instrumentEqualizer}.
7834 Many musically interesting effects, such as swing, articulation,
7835 slurring, etc., are not translated to MIDI.
7840 * MIDI instrument names::
7845 @subsection MIDI block
7849 The MIDI block is analogous to the paper block, but it is somewhat
7850 simpler. The @code{\midi} block can contain:
7854 @item a @code{\tempo} definition
7855 @item context definitions
7858 Assignments in the @code{\midi} block are not allowed.
7862 @cindex context definition
7864 Context definitions follow precisely the same syntax as within the
7865 \paper block. Translation modules for sound are called performers.
7866 The contexts for MIDI output are defined in @file{ly/performer-init.ly}.
7869 @node MIDI instrument names
7870 @subsection MIDI instrument names
7872 @cindex instrument names
7873 @cindex @code{Staff.midiInstrument}
7874 @cindex @code{Staff.instrument}
7876 The MIDI instrument name is set by the @code{Staff.midiInstrument}
7877 property or, if that property is not set, the @code{Staff.instrument}
7878 property. The instrument name should be chosen from the list in
7879 @ref{MIDI instruments}.
7883 If the selected string does not exactly match, then LilyPond uses the
7884 default (Grand Piano). It is not possible to select an instrument by
