85 @subsection Overview of the supported styles
87 Three styles are available for typesetting Gregorian chant:
90 @item @emph{Editio Vaticana} is a complete style for
91 Gregorian chant, following the appearance of the Solesmes
92 editions, the official chant books of the Vatican since 1904.
93 LilyPond has support for all the notational signs used in this
94 style, including ligatures, @emph{custodes}, and special signs
95 such as the quilisma and the oriscus.
98 @cindex Vaticana, Editio
100 @item The @emph{Editio Medicaea} style offers certain features
101 used in the Medicaea (or Ratisbona) editions which were used prior
102 to the Solesmes editions. The most significant differences from
103 the @emph{Vaticana} style are the clefs, which have
104 downward-slanted strokes, and the note heads, which are square and
107 @cindex Ratisbona, Editio
108 @cindex Medicaea, Editio
110 @item The @emph{Hufnagel} (@qq{horseshoe nail}) or @emph{Gothic}
111 style mimics the writing style in chant manuscripts from Germany
112 and Central Europe during the middle ages. It is named after the
113 basic note shape (the @emph{virga}), which looks like a small
118 Three styles emulate the appearance of late-medieval and
119 renaissance manuscripts and prints of mensural music:
122 @item The @emph{Mensural} style most closely resembles the
123 writing style used in late-medieval and early renaissance
124 manuscripts, with its small and narrow, diamond-shaped note heads
125 and its rests which approach a hand-drawn style.
129 @item The @emph{Neomensural} style is a modernized and
130 stylized version of the former: the note heads are broader and the
131 rests are made up of straight lines. This style is particularly
132 suited, e.g., for incipits of transcribed pieces of mensural
137 @item The @emph{Petrucci} style is named after Ottaviano Petrucci
138 (1466-1539), the first printer to use movable type for music (in
139 his @emph{Harmonice musices odhecaton}, 1501). The style uses
140 larger note heads than the other mensural styles.
146 @emph{Baroque} and @emph{Classical} are not complete styles
147 but differ from the default style only in some details: certain
148 note heads (Baroque) and the quarter rest (Classical).
150 Only the mensural style has alternatives for all aspects of the
151 notation. Thus, there are no rests or flags in the Gregorian
152 styles, since these signs are not used in plainchant notation, and
153 the Petrucci style has no flags or accidentals of its own.
155 Each element of the notation can be changed independently of the
156 others, so that one can use mensural flags, petrucci note heads,
157 classical rests and vaticana clefs in the same piece, if one

176 @node Pre-defined contexts
177 @unnumberedsubsubsec Pre-defined contexts
179 For Gregorian chant and mensural notation, there are pre-defined
180 voice and staff contexts available, which set all the various
181 notation signs to values suitable for these styles. If one is
182 satisfied with these defaults, one can proceed directly with note
183 entry without worrying about the details on how to customize a
184 context. See one of the pre-defined contexts
185 @code{VaticanaVoice}, @code{VaticanaStaff}, @code{MensuralVoice},
186 and @code{MensuralStaff}. See further

203 @unnumberedsubsubsec Ligatures
207 @c TODO: Should double check if I recalled things correctly when I wrote
208 @c down the following paragraph by heart.
210 A ligature is a graphical symbol that represents at least two
211 distinct notes. Ligatures originally appeared in the manuscripts
212 of Gregorian chant notation to denote ascending or descending
213 sequences of notes on the same syllable. They are also used in
216 Ligatures are entered by @emph{enclosing} them in @code{\[} and
217 @code{\]}. Some ligature styles may need additional input syntax
218 specific for this particular type of ligature. By default, the
219 @code{LigatureBracket} engraver just puts a square bracket
222 @lilypond[quote,ragged-right,verbatim]
230 Two other ligature styles are available: the Vaticana for
231 Gregorian chant, and the Mensural for mensural music (only white
232 mensural ligatures are supported for mensural music, and with
233 certain limitations). To use any of these styles, the default
234 @code{Ligature_bracket_engraver} has to be replaced with one of the
235 specialized ligature engravers in the @code{Voice} context,
236 as explained in @ref{White mensural ligatures} and
237 @ref{Gregorian square neume ligatures}.
244 @ref{White mensural ligatures},
245 @ref{Gregorian square neume ligatures}.
248 Ligatures need special spacing that has not yet been implemented. As
249 a result, there is too much space between ligatures most of the time,
250 and line breaking often is unsatisfactory. Also, lyrics do not
251 correctly align with ligatures.
253 Accidentals must not be printed within a ligature, but instead need to
254 be collected and printed in front of it.
256 The syntax still uses the deprecated infix style
257 @code{\[ music expr \]}. For consistency reasons, it will eventually
258 be changed to postfix style @code{note\[ ... note\]}.
260 @c Alternatively, the file
261 @c @file{gregorian-init.ly} can be included; it provides a scheme
264 @c \ligature @var{music expr}
266 @c with the same effect and is believed to be stable.
268 @c TODO: this does not seem to work at the moment.
273 @unnumberedsubsubsec Custodes
278 A @emph{custos} (plural: @emph{custodes}; Latin word for @qq{guard})
279 is a symbol that appears at the end of a staff. It anticipates the
280 pitch of the first note of the following line, thus helping the performer
281 to manage line breaks during performance.
283 Custodes were frequently used in music notation until the
284 seventeenth century. Nowadays, they have survived only in a few
285 particular forms of musical notation such as contemporary editions
286 of Gregorian chant like the @emph{Editio Vaticana}. There are
287 different custos glyphs used in different flavors of notational
290 For typesetting custodes, just put a @code{Custos_engraver} into the
291 @code{Staff} context when declaring the @code{\layout} block,
292 and change the style of the custos with an @code{\override} if
293 desired, as shown in the following example:
295 @lilypond[quote,ragged-right]
305 \consists "Custos_engraver"
306 \override Custos.style = #'mensural
312 The custos glyph is selected by the @code{style} property. The styles
313 supported are @code{vaticana}, @code{medicaea}, @code{hufnagel}, and
314 @code{mensural}. They are demonstrated in the following fragment.

409 these clefs, numbered from the lowest to the highest line.
410 You can manually force a clef glyph to be typeset on an arbitrary
411 line, as described in @ref{Clef}. The note printed to the right
412 side of each clef in the example column denotes the @code{c'} with

652 @unnumberedsubsubsec Mensural note heads
654 @cindex note heads, ancient
656 For ancient notation, a note head style other than the
657 @code{default} style may be chosen. This is accomplished by setting
658 the @code{style} property of the @code{NoteHead} object to
659 @code{baroque}, @code{neomensural}, @code{mensural},
660 @code{petrucci}, @code{blackpetrucci} or @code{semipetrucci}.
662 The @code{baroque} style differs from the @code{default} style by:
665 @item Providing a @code{maxima} note head, and
666 @item Using a square shape for @code{\breve} note heads.
669 The @code{neomensural}, @code{mensural}, and @code{petrucci} styles
670 differ from the @code{baroque} style by:
673 @item Using rhomboidal heads for semibreves and all smaller durations,
675 @item Centering the stems on the note heads.
678 The @code{blackpetrucci} style produces note heads usable in black
679 mensural notation or coloratio sections in white mensural notation.
680 Because note head style does not influence flag count, in
681 this style a semiminima should be notated as @code{a8*2}, not
682 @code{a4}, otherwise it will look like a minima.

760 features of classical notation (which however are typically out of
761 scope for mensural notation).

925 There is no additional input language to describe the shape of a
926 white mensural ligature. The shape is rather determined solely from
927 the pitch and duration of the enclosed notes. While this approach may
928 take a new user a while to get accustomed to, it has the great advantage
929 that the full musical information of the ligature is known internally.
930 This is not only required for correct MIDI output, but also allows for
931 automatic transcription of the ligatures.
933 At certain places two consecutive notes can be represented either as
934 two squares or as an oblique parallelogram (flexa shape). In such
935 cases the default is the two squares, but a flexa can be required by
936 setting the @code{ligature-flexa} property of the @emph{second} note
937 head. The length of a flexa can be set by the note head property

1291 There are no rests in Gregorian chant notation; instead, it uses
1294 A @emph{divisio} (plural: @emph{divisiones}; Latin word for
1295 @q{division}) is a staff context symbol that is used to indicate
1296 the phrase and section structure of Gregorian music. The musical
1297 meaning of @emph{divisio minima}, @emph{divisio maior}, and
1298 @emph{divisio maxima} can be characterized as short, medium, and
1299 long pause, somewhat like the breath marks from @ref{Breath marks}.
1300 The @emph{finalis} sign not only marks the end of a chant, but is
1301 also frequently used within a single antiphonal/responsorial chant
1302 to mark the end of each section.
1304 To use divisiones, include the file @file{gregorian.ly}. It
1305 contains definitions that you can apply by just inserting
1306 @code{\divisioMinima}, @code{\divisioMaior}, @code{\divisioMaxima},
1307 and @code{\finalis} at proper places in the input. Some editions use
1308 @emph{virgula} or @emph{caesura} instead of divisio minima.

1450 @node Gregorian square neume ligatures
1451 @unnumberedsubsubsec Gregorian square neume ligatures
1453 @cindex Square neumes ligatures
1454 @cindex Gregorian square neumes ligatures
1456 There is limited support for Gregorian square neumes notation
1457 (following the style of the Editio Vaticana). Core ligatures can
1458 already be typeset, but essential issues for serious typesetting are
1459 still lacking, such as (among others) horizontal alignment of multiple
1460 ligatures, lyrics alignment, and proper handling of accidentals.
1462 The support for Gregorian neumes is enabled by @code{\include}ing
1463 @file{gregorian.ly} at the beginning of the file. This makes available
1464 a number of extra commands to produce the neume symbols used in
1465 plainchant notation.
1469 Note heads can be @emph{modified} and/or @emph{joined}.
1473 the note head can be modified by @emph{prefixing} the note name
1474 with any of the following commands:
1479 @funindex \inclinatum
1483 @funindex \descendens
1485 @funindex \ascendens
1491 @funindex \deminutum
1498 @item Ligatures, properly speaking (i.e. notes joined together), are
1499 produced by placing one of the joining commands @code{\pes} or
1500 @code{\flexa}, for upwards and downwards movement, respectively,
1501 @emph{between} the notes to be joined.
1504 A note name without any qualifiers will produce a @emph{punctum}.
1505 All other neumes, including the single-note neumes with a
1506 different shape such as the @emph{virga}, are in principle
1507 considered as ligatures and should therefore be placed
1508 between @code{\[...\]}.
1509 @c Regarding the @emph{punctum}, @code{b} and @code{\[ b \]} are
1516 @item The @emph{punctum} is the basic note shape (in the
1517 @emph{Vaticana} style: a square with some curvation for
1518 typographical finesse). In addition to the regular
1519 @emph{punctum}, there is also the oblique @emph{punctum
1520 inclinatum}, produced with the prefix @code{\inclinatum}. The
1521 regular @emph{punctum} can be modified with @code{\cavum}, which
1522 produces a hollow note, and @code{\linea}, which draws vertical
1523 lines on either side of the note.
1525 @item The @emph{virga} has a descending stem on the right side. It is
1526 produced by the modifier @code{\virga}.
1532 Unlike most other neumes notation systems, the typographical
1533 appearance of ligatures is not directly dictated by the input
1534 commands, but follows certain conventions dependent on musical
1535 meaning. For example, a three-note ligature with the musical shape
1536 low-high-low, such as @code{\[ a \pes b \flexa g \]}, produces a
1537 Torculus consisting of three Punctum heads, while the shape
1538 high-low-high, such as @code{\[ a \flexa g \pes b \]}, produces a
1539 Porrectus with a curved flexa shape and only a single Punctum
1540 head. There is no command to explicitly typeset the curved flexa
1541 shape; the decision of when to typeset a curved flexa shape is
1542 based on the musical input. The idea of this approach is to
1543 separate the musical aspects of the input from the notation style
1544 of the output. This way, the same input can be reused to typeset
1545 the same music in a different style of Gregorian chant notation.
1550 Another main category of notes in Gregorian chant is the so-called
1551 liquescent neumes. They are used under certain circumstances at
1552 the end of a syllable which ends in a @q{liquescent} letter, i.e.
1553 the sounding consonants that can hold a tone (the nasals, l, r, v,
1554 j, and their diphthong equivalents). Thus, the liquescent neumes
1555 are never used alone (although some of them can be produced), and
1556 they always fall at the end of a ligature.
1558 Liquescent neumes are represented graphically in two different,
1559 more or less interchangeable ways: with a smaller note or by
1560 @q{twisting} the main note upwards or downwards. The first is
1561 produced by making a regular @code{pes} or @code{flexa} and
1562 modifying the shape of the second note:
1563 @code{\[ a \pes \deminutum b \] }, the second by modifying the shape
1564 of a single-note neume with @code{\auctum} and one of the direction
1565 markers @code{\descendens} or @code{\ascendens}, e.g.,
1566 @code{ \[ \auctum \descendens a \] }.
1571 A third category of signs is made up of a small number of signs
1572 with a special meaning (which, incidentally, in most cases is only
1573 vaguely known): the @emph{quilisma}, the @emph{oriscus}, and the
1574 @emph{strophicus}. These are all produced by prefixing a note name
1575 with the corresponding modifier, @code{\quilisma},
1576 @code{\oriscus}, or @code{\stropha}.
1578 Virtually, within the ligature delimiters @code{\[} and @code{\]},
1579 any number of heads may be accumulated to form a single ligature,
1580 and head prefixes like @code{\pes}, @code{\flexa}, @code{\virga},
1581 @code{\inclinatum}, etc. may be mixed in as desired. The use of
1582 the set of rules that underlies the construction of the ligatures
1583 in the above table is accordingly extrapolated. This way,
1584 infinitely many different ligatures can be created.
1586 Note that the use of these signs in the music itself follows
1587 certain rules, which are not checked by LilyPond. E.g., the
1588 @emph{quilisma} is always the middle note of an ascending
1589 ligature, and usually falls on a half-tone step, but it is
1590 perfectly possible, although incorrect, to make a single-note
1593 In addition to the note signs, @file{gregorian.ly} also defines the
1594 commands @code{\versus}, @code{\responsum}, @code{\ij},
1595 @code{\iij}, @code{\IJ}, and @code{\IIJ}, that will produce the
1596 corresponding characters, e.g., for use in lyrics, as section
1597 markers, etc. These commands use special Unicode characters and
1598 will only work if a font is used which supports them.
1603 The following table shows a limited, but still representative pool
1604 of Gregorian ligatures, together with the code fragments that
1605 produce the ligatures. The table is based on the extended neumes
1606 table of the 2nd volume of the Antiphonale Romanum
1607 (@emph{Liber Hymnarius}), published 1983 by the monks of Solesmes.
1608 The first column gives the name of the ligature, with the main form in
1609 boldface and the liquescent forms in italics. The third column
1610 shows the code fragment that produces this ligature, using
1611 @code{g}, @code{a}, and @code{b} as example pitches.

2376 Head prefixes can be accumulated, though restrictions apply. For

2401 When an @code{\augmentum} dot appears at the end of the last staff
2402 within a ligature, it is sometimes vertically placed wrong. As a
2403 workaround, add an additional skip note (e.g., @code{s8}) as last note
2406 @code{\augmentum} should be implemented as a head prefix rather than a
2407 unary music function, such that @code{\augmentum} can be intermixed
2408 with head prefixes in arbitrary order.

2422 @unnumberedsubsubsec Kievan contexts
2424 @cindex KievanVoiceContext
2425 @cindex KievanStaffContext
2427 As with Mensural and Gregorian notation, the predefined
2428 @code{KievanVoice} and @code{KievanStaff} contexts can be used
2429 to engrave a piece in square notation. These contexts initialize
2430 all relevant context properties and grob properties to proper
2431 values, so you can immediately go ahead entering the chant:
2433 @lilypond[quote,ragged-right,verbatim]
2436 \new KievanVoice = "melody" \transpose c c' {
2438 c4 c c c c2 b,\longa
2441 \new Lyrics \lyricsto "melody" {
2442 Го -- спо -- ди по -- ми -- луй.
2450 @rglos{kievan notation}.
2453 LilyPond supports Kievan notation of the Synodal style, as used in
2454 the corpus of chantbooks printed by the Russian Holy Synod in the
2455 1910's and recently reprinted by the Moscow Patriarchate Publishing
2456 House. LilyPond does not support the older (less common) forms of
2457 Kievan notation that were used in Galicia to notate Rusyn plainchant.
2460 @unnumberedsubsubsec Kievan clefs
2464 There is only one clef used in Kievan notation (the Tse-fa-ut Clef).
2465 It is used to indicate the position of @code{c}:
2467 @lilypond[quote,relative=1,notime,verbatim]
2475 @rglos{kievan notation},
2482 @unnumberedsubsubsec Kievan notes
2484 @cindex note heads, ancient
2486 For Kievan square notation, the appropriate note head style needs
2487 to be chosen and the flags and stems need to be turned off.
2488 This is accomplished by calling the @code{\kievanOn} function,
2489 which sets the appropriate properties of the note head, stems,
2490 and flags. Once Kievan note heads are not needed, these
2491 properties can be reverted by calling the @code{\kievanOff}
2494 The Kievan final note, which usually comes at the end of a piece
2495 of music, may be selected by setting the duration to
2496 @code{\longa}. The Kievan recitative mark, used to indicate
2497 the chanting of several syllables on one note, may be selected by
2498 setting the duration to @code{\breve}. The following example
2499 demonstrates the various Kievan note heads:
2501 @lilypond[quote,fragment,ragged-right,verbatim]
2505 b'1 b'2 b'4 b'8 b'\breve b'\longa
2512 @rglos{kievan notation},
2516 @ref{Note head styles}.
2519 LilyPond automatically determines if the stem up or stem down
2520 form of a note is drawn. When setting chant in square notation,
2521 however, it is customary to have the stems point in the same
2522 direction within a single melisma. This can be done manually by
2523 setting the @code{direction} property of the @code{Stem} object.
2525 @node Kievan accidentals
2526 @unnumberedsubsubsec Kievan accidentals
2530 The @code{kievan} style for accidentals is selected with the
2531 @code{glyph-name-alist} property of the grob @code{Accidental}.
2532 The @code{kievan} style provides a sharp and a flat sign
2533 different from the default style. There is no natural sign
2534 in Kievan notation. The sharp sign is not used in Synodal music
2535 but may occur in earlier manuscripts. It has been included
2536 primarily for the sake of compatibility.

2616 @emph{Mensurstriche} (@q{mensuration lines}) is the accepted term
2617 for bar lines that are drawn between the staves of a system but
2618 not through the staves themselves. It is a common way to preserve
2619 the rhythmic appearance of the original, i.e. not having to break
2620 syncopated notes at bar lines, while still providing the
2621 orientation aids that bar lines give.

2637 @node Transcribing Gregorian chant
2638 @unnumberedsubsubsec Transcribing Gregorian chant
2640 Gregorian chant can be transcribed into modern notation with a
2641 number of simple tweaks.
2643 @b{Stems}. Stems can be left out altogether by @code{\remove}-ing
2644 the @code{Stem_engraver} from the Voice context:
2651 \remove "Stem_engraver"
2656 However, in some transcription styles, stems are used
2657 occasionally, for example to indicate the transition from a
2658 single-tone recitative to a fixed melodic gesture. In these cases,
2659 one can use either @code{\override Stem.transparent = ##t} or
2660 @code{\override Stem.length = #0} instead, and restore the stem
2661 when needed with the corresponding @code{\once \override Stem.transparent = ##f} (see example below). When using stems that
2662 carry flags, make sure to set @code{\override Flag.transparent
2665 @b{Timing.} For unmetered chant, there are several alternatives.
2667 The Time_signature_engraver can be removed from the Staff context
2668 without any negative side effects. The alternative, to make it
2669 transparent, will leave an empty space in the score, since the
2670 invisible signature will still take up space.
2672 In many cases, @code{\set Score.timing = ##f} will give good
2673 results. Another alternative is to use @code{\CadenzaOn} and
2676 To remove the bar lines, the radical approach is to @code{\remove}
2677 the Bar_engraver from the Staff context. Again, one may want to
2678 use @code{\override BarLine.transparent = ##t} instead, if an
2679 occasional barline is wanted.
2681 A common type of transcription is recitativic chant where the
2682 repeated notes are indicated with a single breve. The text to
2683 the recitation tone can be dealt with in two different ways:
2684 either set as a single, left-aligned syllable:
2686 @lilypond[verbatim,ragged-right]
2687 \include "gregorian.ly"
2688 chant = \relative c' {
2690 c\breve c4 b4 a c2 c4 \divisioMaior
2691 c\breve c4 c f, f \finalis
2694 verba = \lyricmode {
2695 \once \override LyricText.self-alignment-X = #-1
2696 "Noctem quietam et" fi -- nem per -- fec -- tum
2697 \once \override LyricText.self-alignment-X = #-1
2698 "concedat nobis Dominus" om -- ni -- po -- tens.
2702 \new Voice = "melody" \chant
2703 \new Lyrics = "one" \lyricsto melody \verba
2708 \remove "Time_signature_engraver"
2709 \remove "Bar_engraver"
2710 \override Stem.transparent = ##t
2711 \override Flag.transparent = ##t
2717 This works fine, as long as the text doesn't span a line break. If
2718 that is the case, an alternative is to add hidden notes to the
2719 score, here in combination with changing stem visibility:
2722 @lilypond[verbatim,ragged-right]
2723 \include "gregorian.ly"
2724 chant = \relative c' {
2726 \set Score.timing = ##f

2728 \revert NoteHead.transparent
2729 \override Stem.transparent = ##f \stemUp c4 b4 a
2730 \override Stem.transparent = ##t
2731 \override Flag.transparent = ##t c2 c4 \divisioMaior

2758 Another common situation is transcription of neumatic or
2759 melismatic chants, i.e. chants with a varying number of notes
2760 to each syllable. In this case, one would want to set the
2761 syllable groups clearly apart, usually also the subdivisions of a
2762 longer melisma. One way to achieve this is to use a fixed
2763 @code{\time}, e.g., 1/4, and let each syllable or note group fill
2764 one of these measures, with the help of tuplets or shorter
2765 durations. If the bar lines and all other rhythmical indications
2766 are made transparent, and the space around the bar lines is
2767 increased, this will give a fairly good representation in modern
2768 notation of the original.
2770 To avoid that syllables of different width (such as @qq{-ri} and
2771 @qq{-rum}) spread the syllable note groups unevenly apart, the
2772 @code{'X-extent} property of the @code{LyricText} object may be
2773 set to a fixed value. Another, more cumbersome way would be to
2774 add the syllables as @code{\markup} elements. If further
2775 adjustments are necessary, this can be easily done with
2778 @lilypond[verbatim,quote]

2838 @c Add example of white note heads:
2839 @c In the french baroque some composers used white note heads in slow pieces,
2840 @c mainly in 3/2-time. A quarter looks there like a eighth with a white
2841 @c note head. (Franz-Rudolf Kuhnen)
2843 @c TODO Add example of this:
2844 @c I was referring to e.g. notated a8. a16, which should, if I
2845 @c remember correctly, be interpreted more like a8.. a32 (in the french
2846 @c style). The editor might want to show that rythmic figure above the
2847 @c staff as an hint to performers. (Karl Hammer)
