-LilyPond prints music from a specification that you, the user, supply.
-You have to give that specification using a @emph{language}. This
-document is a gentle introduction to that language, which is called
-Mudela, an acronym of Music Definition Language.
-
-This tutorial will demonstrate how to use Mudela by presenting
-examples of input along with resulting output. We will use English
-terms for notation. In case you are not familiar with those, you may
-consult the glossary that is distributed with LilyPond.
-
-The examples discussed are included in the distribution, in the
-subdirectory @file{input/tutorial/}. It is recommended that you
-experiment with writing Mudela input yourself, to get a feel for
-how LilyPond behaves.
-
-@node The first tune, , , Tutorial
-@section The first tune
-
-
-To demonstrate what LilyPond input looks like, we start off with a
-full fledged, yet simple example. It is a convoluted version
-of the famous menuet in J. S. Bach's @emph{Klavierbuechlein}.

-Enter it (or copy it, the filename is @file{menuet.ly}), compile it
-with LilyPond and view the output. Details of this procedure may vary
-from system to system. To create the output, one would issue the
-command `@code{ly2dvi menuet}'. @file{ly2dvi} is a program that does
-the job of running LilyPond and TeX, handling of titles and
-adjusting of page margins.
-
-If all goes well, the file @file{menuet.dvi} will be created.
-To view this output, issue the command `@code{xdvi menuet}'.
-
-Now that we are familiar with the procedure of producing output, we
-will analyse the input, line by line.
-@ignore
-Let's try to redo this
-@example
-
- % lines preceded by a percent are comments.
-
-@end example
-The percent sign, `@code{%}', introduces a line comment. If you want to
-make larger comments, you can use block comments. These are delimited
-by `@code{%@{}' and `@code{%@}}'
-@end ignore
-@multitable @columnfractions .60 .39
-@item
-@noindent
-@c @example urg: no tt font
-@c @exdent % lines preceded by a percent are comments.
-@exdent @code{% lines preceded by a percent are comments.}
-@c @end example
-@tab
-The percent sign, `@code{%}', introduces a line comment. If you
-want to make larger comments, you can use block comments. These
-are delimited by `@code{%@{}' and `@code{%@}}'
-@end multitable
-@example
-
- \input "paper16.ly"
-
-@end example
-By default, LilyPond will use definitions for a 20
-point@footnote{A point is the standard measure of length for
-printing. One point is 1/72.27 inch.} high staff. We want smaller
-output (16 point staff height), so we must import the settings for
-that size, which is done.@example
-
- \score @{
-
-@end example
- A mudela file combines music with directions for outputting that
-music. The music is combined with the output directions by putting
-them into a @code{\score} block.
-@example
-
- \notes
-
-@end example
- This makes LilyPond ready for accepting notes.
-@example
-
- \relative c''
-
-@end example
- As we will see, pitches are combinations of octave, note name and
-chromatic alteration. In this scheme, the octave is indicated by
-using raised quotes (`@code{'}') and ``lowered'' quotes (commas:
-`@code{,}'). The central C is denoted by @code{c'}. The C one octave
-higher is @code{c''}. One and two octaves below the central C is
-denoted by @code{c} and @code{c,} respectively.
-
-For pitches in a long piece you might have to type many quotes. To
-remedy this, LilyPond has a ``relative'' octave entry mode. In this
-mode, octaves of notes without quotes are chosen such that a note is
-as close as possible (graphically, on the staff) to the the preceding
-note. If you add a high-quote an extra octave is added. The lowered
-quote (a comma) will subtract an extra octave. Because the first note
-has no predecessor, you have to give the (absolute) pitch of the note
-to start with.@example
-
- \sequential @{
-
-@end example
- What follows is sequential music, i.e.,
-notes that are to be played and printed after each other.@example
-
- \time 3/4;
-
-@end example
- This command changes the time signature of the current piece: a 3/4
-sign is printed. This command is also used to generate bar lines in
-the right spots.@example
-
- \key g;
-
-@end example
- This command changes the current key to G-major. Although this
-command comes after the @code{\time} command, in the output, the key
-signature comes before the time signature: LilyPond knows about music
-typesetting conventions. @example
-
- \repeat "volta" 2
-
-@end example
- This command tells LilyPond that the following piece of music must
-be played twice; @code{"volta"} volta brackets should be used for
-alternatives---if there were any.
-@example
-
- @{
-
-@end example
-The subject of the repeat is again sequential music. Since
-@code{\sequential} is such a common construct, a shorthand is provided:
-just leave off @code{\sequential}, and the result is the same. @example
-
- d4
-
-@end example
- This is a note with pitch @code{d} (determined up to octaves). The
-relative music was started with a @code{c''}, so the real pitch of this
-note is @code{d''}. The @code{4} designates the duration of the note
-(it is a quarter note). @example
-
- a b
-
-@end example
-These are notes with pitch @code{a} and @code{b}. Because their
-duration is the same as the @code{g}, there is no need to enter the
-duration (You may enter it anyway, eg. @code{a4 b4}) @example
-
- d4 g, g |
-
-@end example
- Three more notes. The `@code{|}' character is a `barcheck'. When
-processing the music, LilyPond will verify that barchecks are found at
-the start of a measure. This can help you track down errors.
-
- So far, no notes were chromatically altered. Here is the first one
-that is: @code{fis}. Mudela by default uses Dutch note names, and
-``Fis'' is the Dutch note name for ``F sharp''. However, there is no
-sharp sign in the output. The program keeps track of key signatures,
-and will only print accidentals if they are needed.
-@example
-
- c8 d e fis
-
-@end example
-LilyPond guesses were beams can be added to eighth and shorter notes.
-In this case, a beam over 4 eighths is added.
-@example
-
- c4 d8( )c b a( )b4 c8 b a g |
-
-@end example
- The next line shows how to make a slur:
-the beginning and ending note of the slur is marked with an opening and
-closing parenthesis respectively. In the line shown above this is
-done for two slurs. Slur markers (parentheses) are between
-the notes.@example
-
- a4 [b8 a] [g fis]
-
-@end example
-Automatic beaming can be overridden by inserting beam marks
-(brackets). Brackets are put around notes you want beamed.@example
-
- g2. |
-
-@end example
-A duration with augmentation dot is notated
-with the duration number followed by a period.@example
-
- @}
-
-@end example
- This ends the sequential music to be repeated. LilyPond will typeset
-a repeat bar. @example
-
- cis'4 b8 cis a4 |
-
-@end example
- This line shows that Lily will print an accidental if that is
-needed: the first C sharp will be printed with an accidental, the
-second one without. @example
-
- a8-. b-. cis-. d-. e-. fis-.
-
-@end example
-You can enter articulation signs either in a verbose form using a
-shorthand. Here we demonstrate the shorthand: it is formed by a dash
-and the the character for the articulation to use, e.g. `@code{-.}' for
-staccato as shown above. @example
-
- fis a, r8 cis8
-
-@end example
-
-Rests are denoted by the special notename `@code{r}'. You can also enter
-an invisible rest by using the special notename `@code{s}'.
-@example
-
- d2.-\fermata
-
-@end example
- All articulations have a verbose form, like @code{\fermata}. The
-command `@code{\fermata}' is not part of the core of the language (most
-of the other discussed elements are), but it is a shorthand for a more
-complicated description of a fermata. @code{\fermata} names that
-description and is therefore called an @emph{identifier}. @example
-
- @}
-
-@end example
-
-Here the music ends.
-@example
-
- \paper @{
- linewidth = 14.0\cm;
- @}
-
-@end example
-This specifies a conversion from music to notation output. Most of
-the details of this conversions (font sizes, dimensions, etc.) have
-been taken care of, but to fit the output in this document, it has
-to be smaller. We do this by setting the line width to 14 centimeters
-(approximately 6 inches).
-@example
-
- @}
-
-@end example
-The last brace ends the @code{\score} block.
-
-There are two things to note here. The format contains musical
-concepts like pitches and durations, instead of symbols and positions:
-the input format tries to capture the meaning of @emph{music}, and not
-notation. Therefore Second, the format tries to be @emph{context-free}:
-a note will sound the same regardless of the current time signature,
-the key, etc.
-
-The purpose of LilyPond is explained informally by the term `music
-typesetter'. This is not a fully correct name: not only does the
-program print musical symbols, it also makes esthetic decisions. All
-symbols and their placement is @emph{generated} from a high-level musical
-description. In other words, LilyPond would be best
-described by `music compiler' or `music to notation compiler'.

-@end mudela
-
-Again, we will dissect the file line by line.@example
-
- \header @{
-
-@end example
-Information about the music you are about to typeset goes into a
-@code{\header} block. The information in this block is not used by
-LilyPond, but it is included in the output. @file{ly2dvi} uses this
-information to print titles above the music.
-@example
-
- title = "The river is flowing";
- composer = "Traditional (?)";
-@end example
-the @code{\header} block contains assignments. An assignment starts
-with a string. (which is unquoted, in this case). Then comes the
-equal sign `@code{=}'. After the equal sign comes the expression you
-want to store. In this case, you want to put in strings. The
-information has to be quoted here, because it contains spaces. The
-assignment is finished with a semicolon.@example
-
- \include "paper16.ly"
-
-@end example
-Smaller size for inclusion in a book.@example
-
- melody = \notes \relative c' @{
-
-@end example
-The structure of the file will be the same as the previous one, a
-@code{\score} block with music in it. To keep things readable, we will
-give names to the different parts of music, and use the names to
-construct the music within the score block.
-
-@example
-
- \partial 8;
-
-@end example
-
-The piece starts with an anacrusis of one eighth. @example
-
- c4 c8 d [es () d] c4 | f4 f8 g [es() d] c g |
- c4 c8 d [es () d] c4 | d4 es8 d c4.
- \bar "|.";
-
-@end example
-We use explicit beaming. Since this is a song, we will turn automatic
-beams off, and use explicit beaming where needed.@example
-
- @}
-
-@end example
-This ends the definition of @code{melody}. Note that there are no
-semicolons after assignments at top level.@example
-
- text = \lyrics @{
-
-@end example
-Another identifier assignment. This one is for the lyrics.
-Lyrics are formed by syllables that have duration, and not by
-notes. To make LilyPond parse words as syllables, switch it into
-lyrics mode with @code{\lyrics}. Again, the brace after @code{\lyrics}
-is a shorthand for @code{\sequential @{}. @example
-
- The4 ri -- ver is flo- __ wing, flo -- wing and gro -- wing, the
- ri- ver is flo- __ wing down to the sea.
- @}
-
-@end example
-The syllables themselves are separated by spaces. You can get syllable
-extenders by entering `@code{__}', and centered hyphens with
-`@code{-}@code{-}'. We enter the syllables as if they are all quarter notes
-in length (hence the @code{4}), and use a feature to align the
-syllables to the music (which obviously isn't all quarter notes.)
-@example
-
- accompaniment =\chords @{
-
-@end example
-We'll put chords over the music. There is a special mode (analogous
-to @code{\lyrics} and @code{\notes} mode) where you can give the names
-of the chords you want, instead of the notes comprising the chord.
-@example
-
- r8
-
-@end example
-There is no accompaniment during the anacrusis.@example
-
- c2-3- f-3-.7
-
-@end example
-A chord is started by the tonic of the chord. The
-first one lasts a half note. An unadorned note creates a major
-triad, while a minor triad is wanted. @code{3-} modifies the third to
-be small. @code{7} modifies (adds) a seventh, which is small by default
-to create the @code{f a c es} chord. Multiple modifiers must be
-separated by a dot.@example
-
- d-min es4 c8-min r8
-
-@end example
-Some modifiers have predefined names, eg. @code{min} is the same as
-@code{3-}, so @code{d-min} is a minor @code{d} chord.@example
-
- c2-min f-min7 g-7^3.5 c-min @}
-
-@end example
-A named modifier @code{min} and a normal modifier @code{7} do not have
-to be separated by a dot. Tones from a chord are removed with chord
-subtractions. Subtractions are started with a caret, and they are
-also separated by dots. In this example, @code{g-7^3.5} produces a
-minor seventh. The brace ends the sequential music. @example
-
- \score @{
- \simultaneous @{
-
-@end example
-We assemble the music in the @code{\score} block. Melody, lyrics and
-accompaniment have to sound at the same time, so they should be
-@code{\simultaneous}.@example
-
- %\accompaniment
-
-@end example
-Chord mode generates notes grouped in @code{\simultaneous} music. If
-you remove the comment sign, you can see the chords in normal
-notation: they will be printed as note heads on a separate
-staff. @example
-
- \context ChordNames \accompaniment
-
-@end example
-Normally, the notes that you enter are transformed into note heads.
-The note heads alone make no sense, they need surrounding information:
-a key signature, a clef, staff lines, etc. They need @emph{context}. In
-LilyPond, these symbols are created by objects called `interpretation
-context'. Interpretation contexts only exist during a run of
-LilyPond. Interpretation contexts that are for printing music (as
-opposed to playing music) are called `notation context'.
-
-By default, LilyPond will create a Staff contexts for you. If you
-would remove the @code{%} sign in the previous line, you can see that
-mechanism in action.
-
-We don't want default contexts here, because we want names, not note
-heads. An interpretation context can also created upon explicit
-request. The keyword for such a request is @code{\context}. It takes
-two arguments. The first is the name of a interpretation context.
-The name is a string, it can be quoted with double quotes). The
-second argument is the music that should be interpreted in this
-context. For the previous line, we could have written @code{\context
-Staff \accompaniment}, and get the same effect.@example
-
- \addlyrics
-
-@end example
-The lyrics need to be aligned with the melody. This is done by
-combining both with @code{\addlyrics}. @code{\addlyrics} takes two
-pieces of music (usually a melody and lyrics, in that order) and
-aligns the syllables of the second piece under the notes of the
-first piece. If you would reverse the order, the notes would be
-aligned on the lyrics, which is not very useful. (Besides, it looks
-silly.)@example
-
- \context Staff = mel @{
-
-@end example
-This is the argument of @code{\addlyrics}. We instantiate a
-@code{Staff} context explicitly: should you chose to remove comment
-before the ``note heads'' version of the accompaniment, the
-accompaniment will be on a nameless staff. The melody has to be on a
-different staff as the accompaniment. This is accomplished by giving
-the melody staff a different name.@example
-
- \property Staff.noAutoBeaming = "1"
-
-@end example
-An interpretation context has variables that tune its behaviour. One
-of the variables is @code{noAutoBeaming}. If set and non-zero (i.e.,
-true) LilyPond will not try to put automatic beaming on the current
-staff.@example
-
- \property Staff.automaticMelismata = "1"
-
-@end example
-Similarly, we don't want to print a syllable when there is
-a slur. This sets up the Staff context to signal slurs while
-@code{\addlyrics} is processed. @example
-
- \melody
- @}
-
-@end example
-Finally, we put the melody on the current staff. Note that the
-@code{\property} directives and @code{\melody} are grouped in sequential
-music, so the property settings are done before the melody is
-processed. @example
-
- \context Lyrics \text
-
-@end example
-The second argument of @code{\addlyrics} is the text. The text also
-should not land on a Staff, but on a interpretation context for
-syllables, extenders, hyphens etc. This context is called
-Lyrics.@example
-
- @}
-
-@end example
-This ends @code{\simultaneous}.@example
-
- \midi @{ @}
-
-@end example
-This makes the music go to a MIDI file. MIDI is great for
-checking music you enter. You listen to the MIDI file: if you hear
-something unexpected, it's probably a typing error. @code{\midi} is an
-`output definition', a declaration that specifies how to output music
-analogous to @code{\paper @{ @}}.@example
-
- \paper @{ linewidth = 10.0\cm; @}
-
-@end example
-We also want notation output. The linewidth is short so the piece
-will be set in two lines. @example
-
- @}
-
-@end example
-End the score block.

-If it looks like incomprehensible gibberish to you@dots{} Then you are

-viola = \notes \relative c' \context Voice = viola @{
-@end example
-In this example, you can see multiple parts on a staff. Each part is
-associated with one notation context. This notation context handles
-stems and dynamics (among others). The name of this context is
-@code{Voice}. For each part we have to make sure that there is
-precisely one Voice context@footnote{If @code{\context} would not
-have been specified explicitly, three @code{Voice} contexts would be
-created: one for each note in the first chord.}.@example
-<c4-\f g' c>
-@end example
-@code{<} and @code{>} are short hands for @code{\simultaneous @{} and
-@code{@}}. So the expression enclosed in @code{<} and @code{>} is a
-chord. @code{\f} places a forte symbol under the chord.@example
-\property Voice.verticalDirection = \down
-@end example
-@code{verticalDirection} is a property of the voice context. It
-controls the directions of stems, articulations marks and other
-symbols.
- If @code{verticalDirection} is set to @code{\down}
-(identifier for the integer -1) the stems go down,
-@code{\up} (identifier for the integer 1) makes the stems go up.@example
- g'8. b,16
-@end example
-Relative octaves work a little differently with chords. The starting
-point for the note following a chord is the first note of the chord. So
-the @code{g} gets an octave up quote: it is a fifth above the starting
-note of the previous chord (the central C).
-
-@example
-s1 s2. r4
-@end example
-@code{s} is a `spacer' rest. It does not print anything, but it does
-have the duration of a rest. @example
-oboes = \notes \relative c'' \context Voice = oboe @{
-@end example
-Now comes a part for two oboes. They play homophonically, so we
-print the notes as one voice that makes chords. Again, we insure that
-these notes are indeed processed by precisely one context with
-@code{\context}.@example
-\stemup s4 g8. b,16 c8 r <e'8.-\p g> <f16 a>
-@end example
-@code{\stemup} is an identifier reference. It is shorthand for
-@code{\property Voice.verticalDirection = \up}. If possible, you
-should use predefined identifiers like these for setting properties.
-Your input will be less dependent upon the implementation of LilyPond.
-@example
-\grace <e8( g> < )d4 f> <c2 e>
-@end example
-@code{\grace} introduces grace notes. It takes one argument, in this
-case a chord. The slur started on the @code{e} of the chord
-will be attached to the next note.@footnote{LilyPond will squirm
-about unended Slurs. In this case, you can ignore the warning}.
-@example
-\times 2/3
-@end example
-Tuplets are made with the @code{\times} keyword. It takes two
-arguments: a fraction and a piece of music. The duration of the
-second argument is multiplied by the first argument. Triplets make
-notes occupy 2/3 of their notated duration, so in this case the
-fraction is 2/3. @example
-@{ <d8 \< f> <e g> <f a> @}
-@end example
-The piece of music to be `tripletted' is sequential music containing
-three notes. On the first chord (the @code{d}), a crescendo is started
-with @code{\<}.@example
-<
-@end example
-At this point, the homophonic music splits into two rhythmically
-different parts. We can't use a sequence of chords to enter this, so
-we make a `chord' of sequences to do it. We start with the upper
-voice, which continues with upward stems: @example
- @{ \times 2/3 @{ a8 g c @} \! c2 @}
-@end example
-The crescendo is ended at the half note by the escaped exclamation
-mark `@code{\!}'. @example
-\context Voice = oboeTwo @{
-\stemdown
-@end example
-We can't share stems with the other voice, so we have to create a new
-@code{Voice} context. We give it the name @code{oboeTwo} to distinguish
-it from the other context. Stems go down in this voice. @example
-\grace @{
-@end example
-When a grace section is processed, a @code{Grace} context is
-created. This context acts like a miniature score of its own. It has
-its own time bookkeeping, and you can make notes, beams, slurs
-etc. Here fiddle with a property and make a beam. The argument of
-@code{\grace} is sequential music.@example
-\property Grace.verticalDirection = \down
-[f,16 g] @}
-@end example
-Normally, grace notes are always stem up, but in this case, the upper
-voice interferes. We set the stems down here.
-
-As far as relative mode is concerned, the previous note is the
-@code{c'''2} of the upper voice, so we have to go an octave down for
-the @code{f}.
-@example
-
- f8 e e2
-@} >
-@end example
-This ends the two-part section. @example
-\stemboth
-\grace <c,8( e> <)b8. d8.-\trill> <c16 e> |
-@end example
-@code{\stemboth} ends the forced stem directions. From here, stems are
-positioned as if it were single part music.
-
-The bass has a little hoom-pah melody to demonstrate parts switching
-between staffs. Since it is repetitive, we use identifiers:@example
-hoomPah = \notes \transpose c' @{
-@end example
-Transposing can be done with @code{\transpose}. It takes two
-arguments; the first specifies what central C should be transposed to.
-The second is the to-be-transposed music. As you can see, in this
-case, the transposition is a no-op. Central C is transposed to
-central C.
-
-The purpose of this no-op is circumventing relative mode. Relative
-mode can not be used in conjunction with transposition, so relative
-mode will leave the contents of @code{\hoomPah} alone. We can use it
-without having to worry about getting the motive in a wrong
-octave@footnote{@code{hoomPah = \relative @dots{}} would be more
-intuitive to use, but that would not let me plug @code{\transpose}
-:-).}.@example
-c8 \translator Staff = top \stemdown
-@end example
-We assume that the first note will be put in the lower staff. After
-that note we switch to the upper staff with @code{\translator}. To be
-precise, this @code{\translator} entry switches the current voice to a
-@code{Staff} named @code{top}. So we have to name the upper staff
-`@code{top}'. Stem directions are set to avoid interfering with the
-oboe voices. @example
-c'8 \translator Staff = bottom \stemup @}
-@end example
-Then a note is put on the upper staff, and we switch again. We have
-to name the lower staff `@code{bottom}'. @example
-hoomPahHoomPah = @{ [\hoomPah \hoomPah] @}
-@end example
-Put two of these fragments in sequence, and beam them.@example
-bassvoices = \notes \relative c' @{
-c4 g8. b,16
-\hoomPahHoomPah \hoomPahHoomPah \hoomPahHoomPah
-\hoomPahHoomPah
-@end example
-Entering the bass part is easy: the hoomPahHoomPah variable is
-referenced four times.@example
-\context Voice = reallyLow @{\stemdown g2 ~ | g4 c8 @} >
-@end example
-After skipping some lines, we see @code{~}. This mark makes ties.@example
-\context PianoStaff
-@end example
-For piano music, a special context is needed to get cross staff
-beaming right. It is called @code{PianoStaff}.@example
-\context Staff = bottom < \time 2/2; \clef bass;
-@end example
-The bottom staff must have a different clef.@example
-indent = 0.0;
-@end example
-To make some more room on the line, the first (in this case the only)
-line is not indented. The line still looks is very cramped, but that is due
-to the format of this tutorial.
-
-This example shows a lot of features, but the organisation isn't
-perfect. For example, it would be less confusing to use a chord
-containing sequential music than a sequence of chords for the oboe
-parts.

-
-This document@footnote{This document has been revised for
-LilyPond 1.2.} describes the the GNU LilyPond input format, which is
-a language for defining music. We call this language @emph{Music
-Definition Language} or @emph{Mudela}, for short.@footnote{If anybody
-comes up with a better name, we'd gladly take this. Gourlay already
-uses a ``Musical Description Language,'' ISO standard 10743 defines a
-``Standard Music Description Language.'' We're not being original
-here.}
-
-@emph{Mudela} is a language that allows you to
-
-@itemize @bullet
- @item create musical expressions by combining pitches, durations
- @item output those musical expressions to various formats
- @item give those musical expressions and output definitions names, so
- you can enter them in manageable chunks.
-@end itemize
-
-@emph{Mudela} aims to define a piece of music completely, both from
-typesetting and from a performance point of view.

-
-This section describes what you may enter at top level.
-
-
-
-@cindex score definition
-
-The output is generated combining a music expression with an output
-definition. A score block has the following syntax:
-
-@example
- \score @{ @var{musicexpr} @var{outputdefs} @}
-@end example
-
-@var{outputdefs} are zero or more output definitions. If no output
-definition is supplied, the default @code{\paper} block will be added.
-
-
-
-@cindex header
-
-@keyindex{header}
-
-The syntax is
-
-@example
- \header @{ @var{key1} = @var{val1};
- @var{key2} = @var{val2}; @dots{} @}
-@end example
-
-A header describes the file's contents. It can also appear in a
-@code{\score} block. Tools like @code{ly2dvi}@indexcode{ly2dvi} can use this
-information for generating titles. Key values that are used by
-@code{ly2dvi} are: title, subtitle, composer, opus, poet, instrument,
-metre, arranger, piece and tagline.
-
-It is customary to put the @code{\header} at the top of the file.

-@node notenames, , , Reference Manual
-
-Note name tables can be specified using
-
-@example
- \notenames@keyindex{notenames}
- @{ @var{assignmentlist} @}
-@end example
-
-@var{assignmentlist} is a list of definitions of the form
-
-@example
- @var{name} = @var{pitch}
-@end example
-
-Chord modifiers can be set analogously, with
-@code{\chordmodifiers}@keyindex{chordmodifiers}.
-
-A @code{\paper} block at top level sets the default paper block. A
-@code{\midi} block at top level works similarly.
-
-
-
-LilyPond contains a Scheme interpreter (the GUILE library) for
-internal use. The following commands access the interpreter
-directly.
-
-@example
- \scm @keyindex{scm} @var{scheme} ;
-@end example
-
-Evaluates the specified Scheme code. The result is discarded.
-
-@example
-\scmfile@keyindex{scmfile} @var{filename};
-@end example
-
-Reads Scheme code from the specified file. The result is discarded.

-@cindex real
-
-
-Formed from an optional minus sign and a sequence of digits followed

-
-
-
-@cindex string
-
-
-Begins and ends with the `@code{"}' character. To include a `@code{"}'

-
-
-The tokenizer accepts the following commands. They can appear
-anywhere.
-

-
-@cindex modes
-
-@node modes, , , Reference Manual
-
-To simplify entering notes, lyrics, and chords, @emph{Mudela} has three
-special input modes on top of the default mode. In each mode, words
-are identified on the input. If @code{"word"} is encountered, it is
-treated as a string. If @code{\word} is encountered, it is treated as
-a keyword or as an identifier. The behavior of the modes differs in
-two ways: Different modes treat unquoted words differently, and
-different modes have different rules for deciding what is a word.
-
-@table @samp
- @item Normal mode.
-@cindex mode!normal
-
- At the start of parsing, @emph{Mudela} is in Normal mode. In Normal
- mode, a word is an alphabetic character followed by alphanumeric
- characters. If @code{word} is encountered on the input it is
- treated as a string.
-
- @item Note mode.
-@cindex mode!note
-
- Note mode is introduced by the keyword
- @code{\notes}@keyindex{notes}. In Note mode, words can only
- contain alphabetic characters. If @code{word} is encountered,
- LilyPond first checks for a notename of @code{word}. If no
- notename is found, then @code{word} is treated as a string.
-
- Since combinations of numbers and dots are used for indicating
- durations, it is not possible to enter real numbers in this mode.
-
- @item Chord mode.
-@cindex mode!chord
-
- Chord mode is introduced by the keyword
- @code{\chords}@keyindex{chords}. It is similar to Note mode, but
- words are also looked up in a chord modifier table (containing
- @code{maj}, @code{dim}, etc).
-
- Since combinations of numbers and dots are used for indicating
- durations, you can not enter real numbers in this mode. Dashes
- and carets are used to indicate chord additions and subtractions,
- so scripts can not be entered in Chord mode.
-
- @item Lyrics mode.
-@cindex mode!lyric
-
- Lyrics mode is introduced by the keyword
- @code{\lyrics}@keyindex{lyrics}. This mode has rules that make it
- easy to include punctuation and diacritical marks in words. A
- word in Lyrics mode begins with: an alphabetic character,
- `@code{_}', `@code{?}', `@code{!}', `@code{:}', `@code{'}', the
- control characters @code{^A} through @code{^F}, @code{^Q} through
- @code{^W}, @code{^Y}, @code{^^}, any 8-bit character with ASCII code
- over 127, or a two-character combination of a backslash followed
- by one of `@code{`}', `@code{'}', `@code{"}', or
- `@code{^}'.@footnote{The purpose of Lyrics mode is that you can
- enter lyrics in TeX format or a standard encoding without
- needing quotes. The precise definition of this mode indeed is
- ludicrous. This will remain so until the authors of LilyPond
- acquire a deeper understanding of character encoding, or someone
- else steps up to fix this.}
-
- Subsequent characters of a word can be any character that is not
- a digit and not white space. One important consequence of this
- is that a word can end with `@code{@}}', which may be confusing if
- you thought the closing brace was going to terminate Lyrics
- mode.@footnote{LilyPond will issue a warning, though.} Any
- `@code{_}' characters which appear in an unquoted word are
- converted to spaces. This provides a mechanism for introducing
- spaces into words without using quotes. Quoted words can also be
- used in Lyrics mode to specify words that cannot be written with
- the above rules. Here are some examples. Not all of these words
- are printable by TeX.
-
-
- @quotation
-
-@example
-Ah! % a word
-2B_||_!2B % not a word because it starts with a digit
-``Hello'' % not a word because it starts with `
-_ _ _ _ % 4 words, each one a space
-@end example
-
- @end quotation
-
- Since combinations of numbers and dots are used for indicating
- durations, you can not enter real numbers in this mode.
-@end table
-
-It is possible to create words that break the rules by prefixing them
-with the dollar sign `@code{$}@indexcode{$}'. Regardless of the context, a
-word beginning with `@code{$}' extends until the next white space
-character. Such words can contain numbers (even in Note mode), or
-other forbidden characters. The dollar sign can be used to create
-and access identifiers that could not otherwise be used.@footnote{Use
-of `@code{$}' hampers readability and portability to future LilyPond
-versions, thus the use of the dollar sign is discouraged.}

-@node Types, , , Reference Manual
-@section Types
-
-@cindex types and identifiers
-
-@emph{Mudela} has a limited set of types:
-
-@itemize @bullet
- @item integers
- @item reals
- @item strings
- @item music expressions
- @item durations of notes and rests (specified with
- @code{\notenames}@keyindex{notenames})
- @item note name tables
- @item context definitions, part of output definitions. See
- section XREF-contextdefs [FIXME] for more information
- @item output definitions (like @code{\paper}@keyindex{paper} blocks
- and @code{\midi}@keyindex{midi} blocks)
- @item score definitions (@code{\score}@keyindex{score} blocks)
-@end itemize
-
-Type is a syntactical property: @emph{Mudela} has no real type system,
-so there is no support for generic expressions, functions, or user
-defined types. For the same reason, it is not possible to mix reals
-and integers in arithmetic expressions, and ``type
-errors''
-@cindex type error
- (e.g., using a string identifier to
-initialize a @code{\paper}@keyindex{paper} block) will yield a ``parse
-error''.
-
-Identifiers allow objects to be assigned to names. To assign an
-identifier, you use `@var{name}=@var{value}' and to refer to an
-identifier, you preceed its name with a backslash:
-`@code{\}@var{name}'. Identifier assignments must appear at top level
-in the @emph{Mudela} file. Semicolons are forbidden after assignments
-appearing at top level but they are obligatory after assignments
-appearing in the @code{\paper} block, see Section XREF-paper [FIXME].
-
-@var{value} is any of the types listed above.
-
-An identifier can be created with any string for its name, but you
-will only be able to refer to identifiers whose names begin with a
-letter, being entirely alphanumeric. It is impossible to refer to an
-identifier whose name is the same as the name of a keyword.
-
-The right hand side of an identifier assignment is parsed completely
-before the assignment is done, so it is allowed to redefine an
-identifier in terms of its old value, e.g.
-
-@example
- foo = \foo * 2.0
-@end example
-
-When an identifier is referenced, the information it points to is
-copied. Therefore it only makes sense to put identifiers for
-translators, output definitions, and @code{\score}@keyindex{score}
-blocks as the first item in a block. For this reason, if you
-reference a @code{\foo} variable in a @code{\foo} block, it must be the
-first item in the list following @code{\foo}.@footnote{@code{\paper@{\one
-\two@}} does not make sense, because the information of @code{\two}
-would overwrite the information of @code{\one}, thereby making the
-reference to the first identifier useless.}

-The syntax for pitch specification is
-
-
-@example
- \musicalpitch@keyindex{musicalpitch} @{ @var{octave} @var{note} @var{shift} @}
-@end example
-
-@var{octave} is specified by an integer, zero for the octave
-containing middle C. @var{note} is a number from 0 to 7, with 0
-corresponding to C and 7 corresponding to B. The shift is zero for a
-natural, negative to add flats, or positive to add sharps.
-
-In Note and Chord mode, pitches may be designated by names. See
-section XREF-notelang [FIXME] for pitch names in different languages.
-
-The syntax for duration specification is
-
-@example
- \duration@keyindex{duration}
- @{ @var{length} @var{dotcount} @}
-@end example
-
-@var{length} is the negative logarithm (base 2) of the duration:
-1 is a half note, 2 is a quarter note, 3 is an eighth
-note, etc. The number of dots after the note is given by
-@var{dotcount}.
-
-In Note, Chord, and Lyrics mode, durations may be designated by

-@end example
-
-The pitch of the note is specified by the note's name.
-
-
-The default names are the Dutch note names. The notes are specified
-by the letters `@code{c}' through `@code{b}', where `@code{c}' is an
-octave below middle C and the letters span the octave above that C.
-In Dutchcindex(notenames!Dutch), a sharp is formed by adding
-`@code{-is}' to the end of a pitch name. A flat is formed by adding
-`@code{-es}'. Double sharps and double flats are obtained by adding
-`@code{-isis}' or `@code{-eses}'. `@code{aes}' and `@code{ees}' are
-contracted to `@code{as}' and `@code{es}' in Dutch, but both forms will
-be accepted.
-
-LilyPond has predefined sets of notenames for various languages. See
-section XREF-notelang [FIXME] for details.
-
-
-The optional octave specification takes the form of a series of

-
-Commands are music expressions that have no duration.
-
-
-@example
-
- @code{\key}@keyindex{key} @var{pitch} @var{type} @code{;}
-@end example
-
-Change the key signature. @var{type} should be
-@code{\major}@keyindex{major} or @code{\minor}@keyindex{minor} to get
-@var{pitch}-major or @var{pitch}-minor, respectively. The second
-argument is optional; the default is major keys. The @var{\context}
-argument can also be given as an integer, which tells the number of
-semitones that should be added to the pitch given in the subsequent
-@code{\key}@keyindex{key} commands to get the corresponding major key,
-e.g., @code{\minor}@keyindex{minor} is defined as 3. The standard
-mode names @code{\ionian}@keyindex{ionian},
-@code{\locrian}@keyindex{locrian}, @code{\aeolian}@keyindex{aeolian},
-@code{\mixolydian}@keyindex{mixolydian}, @code{\lydian}@keyindex{lydian},
-@code{\phrygian}@keyindex{phrygian}, and @code{\dorian}@keyindex{dorian}
-are also defined.
-
-@example
-
- @code{\keysignature}@keyindex{keysignature} @var{pitchseq} @code{;}
-@end example
-
-Specify an arbitrary key signature. The pitches from @var{pitch} will
-be printed in the key signature in the order that they appear on the
-list.
-
-
-@example
- \mark@keyindex{mark} @var{unsigned};
- \mark @var{string};
-@end example
-
-Prints a mark over or under (depending on the
-@code{markDirection}@indexcode{markDirection} property) the staff. You must add
-@code{Mark_engraver}@indexcode{Mark_engraver} to either the Score or Staff context for
-this to work.
-
-@node barlines, , , Reference Manual
-
-@example
- \bar@keyindex{bar} @var{bartype};
-@end example
-
-This is a request to print a special bar symbol. It replaces the
-regular bar symbol with a special
-symbol. The argument @var{bartype} is a string which specifies the
-kind of bar to print. Options are @code{":|"}

-@cindex "|F@@@code{.|}
-, and @code{".|."}
-@cindex "|G@@@code{.|.}
-.
-These produce, respectively, a right repeat, a left repeat, a double
-repeat, a double bar, a start bar, an end bar, and a thick double
-bar. If @var{bartype} is set to @code{"empty"} then nothing is
-printed, but a line break is allowed at that spot.
-
-You are encouraged to use @code{\repeat} for repetitions.
-See section XREF-sec-repeats [FIXME].
-
-
-
-@example
- \cadenza@keyindex{cadenza} @var{togglevalue} @code{;}
-@end example
-
-Music expression that toggles the automatic generation of bar lines.
-If @var{togglevalue} is 1, bar line generation is turned off. If
-@var{togglevalue} is 0, a bar line is immediately printed and
-automatic bar generation is turned on.
-
-@example
-
- \time@keyindex{time} @var{numerator}@code{/}@var{denominator} @code{;}
-@end example
-
-Change the time signature. The default time signature is 4/4.
-The time signature is used to generate bar lines.
-
-@example
-
- \tempo@keyindex{tempo} @var{duration} = @var{perminute} @code{;}
-@end example
-
-Used to specify the tempo. For example, `@code{\tempo 4 = 76;}'
-requests output with 76 quarter notes per minute.
-
-@example
-
- \partial@keyindex{partial} @var{duration} @code{;}

-lasting two eighth notes.
-
-@example
-
- @code{|}@indexcode{|}
-@cindex bar check
-
-@end example
-
-@cindex shorten measures
-
-@cindex upstep
-
-`@code{|}' is a barcheck. Whenever a barcheck is encountered during
-interpretation, a warning message is issued if it doesn't fall at a
-measure boundary. This can help you finding errors in the input.
-The beginning of the measure will be relocated, so this can also
-be used to shorten measures.
-
-
-@example
-
- \penalty@keyindex{penalty} @var{int} @code{;}

-
-Interpret @var{musicexpr} within a context of type @var{contexttype}.
-If the context does not exist, it will be created. The new context

-@cindex sequential music
-
-
-
-@example
-

- @code{@{} @var{musicexprlist} @code{@}}
-@end example
-
-This means that list should be played or written in sequence, i.e.,
-the second after the first, the third after the second. The duration
-of sequential music is the the sum of the durations of the elements.
-There is a shorthand, which leaves out the keyword:

-@indexcode{>}
-
-@example
-
- \simultaneous@keyindex{simultaneous}
- @code{@{} @var{musicexprlist} @code{@}}
-@end example
-
-It constructs a music expression where all of its arguments start at
-the same moment. The duration is the maximum of the durations of the
-elements. The following shorthand is a common idiom:
-
-@example
-
- @code{<} @var{musicexprlist} @code{>}
-@end example
-
-If you try to use a chord as the first thing in your score, you might

-This happens because the chord is interpreted by a score context.

-@cindex relative pitch specification
-
-@node relative, , , Reference Manual
-
-It is easy to get confused by octave changing marks and accidentally
-putting a pitch in the wrong octave. A much better way of entering a
-note's octave is `the relative octave' mode.
-
-@example
-
- \relative@keyindex{relative} @var{startpitch} @var{musicexpr}
-@end example
-
-The octave of notes that appear in @var{musicexpr} are calculated as
-follows: If no octave changing marks are used, the basic interval
-between this and the last note is always taken to be a fourth or
-less.@footnote{The interval is determined without regarding
-accidentals. A @code{fisis} following a @code{ceses} will be put above
-the @code{ceses}.} The octave changing marks `@code{'}' and `@code{,}'
-can then be added to raise or lower the pitch by an extra octave.
-Upon entering relative mode, an absolute starting pitch must be
-specified that will act as the predecessor of the first note of
-@var{musicexpr}.
-
-Entering scales is straightforward in relative mode.
-
-@mudela[fragment,verbatim,center]
- \relative c' {
- c d e f g a b c c,
- }
-@end mudela
-
-And octave changing marks are used for intervals greater than a fourth.
-
-@mudela[fragment,verbatim,center]
- \relative c'' {
- c g c f, c' a, e'' }
-@end mudela
-
-If the preceding item is a chord, the first note of the chord is used
-to determine the first note of the next chord. But other notes
-within the second chord are determined by looking at the immediately
-preceding note.
-
-@mudela[fragment,verbatim,center]
- \relative c' {
- c <c e g>
- <c' e g>
- <c, e' g>
- }
-@end mudela
-
-The pitch after the @code{\relative} contains a notename. To parse
-the pitch as a notename, you have to be in note mode, so there must
-be a surrounding @code{\notes}@keyindex{notes} keyword (which is not
-shown here).
-
-The relative conversion will not affect @code{\transpose} or
-@code{\relative} sections in its argument. If you want to use
-relative within transposed music, you must place an additional
-@code{\relative} inside the @code{\transpose}.
-
-It is strongly recommended to use relative pitch mode: less work,
-less error-prone, and more readable.
-
-
-
-Chord names are a way to generate simultaneous music expressions that
-correspond with traditional chord names. It can only be used in
-Chord mode (see section XREF-modes [FIXME]).
-
-@example
-
- @var{tonic}[@var{duration}][@code{-}@var{modifiers}][@code{^}@var{subtractions}][@code{/}@var{inversion}].
-@end example
-
-@var{tonic} should be the tonic note of the chord, and @var{duration}
-is the chord duration in the usual notation. There are two kinds of
-modifiers. One type is @emph{chord additions}, which are obtained by
-listing intervals separated by dots. An interval is written by its
-number with an optional `@code{+}' or `@code{-}' to indicate raising or
-lowering by half a step. Chord additions has two effects: It adds
-the specified interval and all lower odd numbered intervals to the
-chord, and it may lower or raise the specified interval. Intervals
-must be separated by a dot (`@code{.}').

-which 3 notes have the length of 2, so the notes are 2/3 of

-
-You cannot have the grace note after the main note, in terms of
-duration, and main notes, but you can typeset the grace notes to the
-right of the main note using the property
-@code{graceAlignPosition}@indexcode{graceAlignPosition}.
-
-When grace music is interpreted, a score-within-a-score is set up:
-@var{musicexpr} has its own time bookkeeping, and you could (for
-example) have a separate time signature within grace notes. While in
-this score-within-a-score, you can create notes, beams, slurs, etc.
-Unbeamed eighth notes and shorter by default have a slash through the
-stem. This behavior can be controlled with the
-@code{stemStyle}@indexcode{stemStyle} property.

-@cindex automatic beam generation
-
-@node autobeam, , , Reference Manual
-
-By default, LilyPond will generate beams automatically. This feature
-can be disabled by setting the @code{Voice.noAutoBeaming}@indexcode{Voice.noAutoBeaming}
-property to 1. It can be overridden for specific cases by
-specifying explicit beams as described in
-section XREF-manualbeam [FIXME].
-
-A large number of Voice properties are used to decide how to generate
-beams. Their default values appear in @file{auto-beam-settings.ly}.
-In general, beams can begin anywhere, but their ending location is
-significant. Beams can end on a beat, or at durations specified by
-the @code{Voice.beamAutoEnd}@indexcode{Voice.beamAutoEnd} property. To end beams every
-quarter note, for example, you could set
-@code{Voice.beamAutoEnd}@indexcode{Voice.beamAutoEnd} equal to `@code{"1/4"}'. To end beams
-at every three eighth notes you would set it to `@code{"3/8"}'. The
-same syntax can be used to specify beam starting points using
-@code{Voice.beamAutoBegin}@indexcode{Voice.beamAutoBegin}.
-
-To allow different settings for different time signatures, these
-property names can start with `@code{time}@var{N}@code{_}@var{M}' to
-restrict the definition to `@var{N}@code{/}@var{M}' time. For example,
-to specify beams ending only for 6/8 time you would use the
-property @code{Voice.time6_8beamAutoEnd}. To allow different endings
-for notes of different durations, the duration can be tacked onto the
-end of the property. To specify beam endings for beams that contain
-32nd notes, you would use @code{Voice.beamAutoEnd_32}.

-@node Notation Contexts, , , Reference Manual
-@section Notation Contexts
-
-@cindex notation contexts
-
-Notation contexts are objects that only exist during a run of
-LilyPond. During the interpretation phase of LilyPond, the Music
-expression contained in a @code{\score} block is interpreted in time
-order. This is the order in which humans read, play, and write
-music.
-
-A context is an object that holds the reading state of the
-expression; it contains information like
-
-@itemize @bullet
- @item What notes are playing at this point?
- @item What symbols will be printed at this point?
- @item In what style will they printed?
- @item What is the current key signature, time signature, point within
- the measure, etc.?
-@end itemize
-
-Contexts are grouped hierarchically: A @code{Voice} context is
-contained in a @code{Staff} context (because a staff can contain
-multiple voices at any point), a @code{Staff} context is contained in
-a @code{Score}, @code{StaffGroup}, or @code{ChoirStaff} context (because
-these can all contain multiple staffs).
-
-Contexts associated with sheet music output are called @emph{notation
-contexts}, those for sound output are called playing contexts.
-
-Contexts are created either manually or automatically. Initially,
-the top level music expression is interpreted by the top level
-context (the @code{Score} context). When a atomic music expression
-(i.e. a note, a rest, @code{\bar}, or @code{\time} commands), a nested
-set of contexts is created that can process these atomic expressions,
-as in this example:
-
-@example
-
- @example
-\score @{ \notes < c4 > @}
-@end example
-
-@end example
-
-The sequential music, `@code{@{ c4 @}}' is interpreted by @code{Score}
-context. When the note `@code{c4}' itself is interpreted, a set of
-contexts is needed that will accept notes. The default for this is a
-@code{Voice} context, contained in a @code{Staff} context. Creation of
-these contexts results in the staff being printed.
-
-
-@node contextselection, , , Reference Manual
-
-@cindex context
-
-You can also create contexts manually, and you probably have to do so
-if you want to typeset complicated multiple part material. If a
-`@code{\context} @var{name} @var{musicexpr}' expression is encountered
-during the interpretation phase, the @var{musicexpr} argument will be
-interpreted with a context of type @var{name}. If you specify a name,
-the specific context with that name is searched.
-
-If a context of the specified type and name can not be found, a new
-one is created. For example,
-
-@quotation
-
-@mudela[verbatim]
-\score {
- \notes \relative c'' {
- c4 <d4 \context Staff = "another" e4> f
- }
-}
-
-@end mudela
-@end quotation
-
-In this example, the @code{c} and @code{d} are printed on the
-default staff. For the @code{e}, a context Staff called
-`@code{another}' is specified; since that does not exist, a new
-context is created. Within @code{another}, a (default) Voice context
-is created for the @code{e4}. When all music referring to a
-context is finished, the context is ended as well. So after the
-third quarter, @code{another} is removed.
-
-Almost all music expressions inherit their interpretation context
-from their parent. In other words, suppose that the syntax for a
-music expression is
-
-@example
-
- \keyword @var{musicexpr1} @var{musicexpr2} @dots{}
-@end example
-
-When the interpretation of this music expression starts, the context
-for @var{musicexpr1}, @var{musicexpr2}, etc. is that of the total
-expression.
-
-Lastly, you may wonder, why this:
-
-@quotation
-
-@example
-\score @{
- \notes \relative c'' @{
- c4 d4 e4
- @}
-@}
-@end example
-
-@end quotation
-
-doesn't result in this:
-
-@mudela[]
-
- \score {
- \notes \relative c'' {
- <c4> <d4> <e4>
- }
- }
-
-@end mudela
-
-For the @code{c4}, a default @code{Staff} (with a contained
-@code{Voice}) context is created. After the @code{c4} ends, no
-music refers to this default staff, so it would be ended, with the
-result shown. To prevent this inconvenient behavior, the context to
-which the sequential music refers is adjusted during the
-interpretation. So after the @code{c4} ends, the context of the
-sequential music is also the default @code{Voice} context.
-The @code{d4} gets interpreted in the same context
-as @code{c4}.
-
-
-
-These are the contexts supplied with the package. They are defined
-in the initialization file @file{ly/engraver.ly}.
-
-@table @samp
- @item @code{Grace}@indexcode{Grace}
- The context for handling grace notes. It is instantiated
- automatically when you use @code{\grace}. Basically, it is an
- `embedded' miniature of the Score context. Since this context
- needs special interaction with the rest of LilyPond, you should
- not explicitly instantiate it.
-
- @item @code{LyricVoice}@indexcode{LyricVoice}
- Corresponds to a voice with lyrics. Handles the printing of a
- single line of lyrics.
-
- @item @code{Thread}@indexcode{Thread}
- Handles note heads, and is contained in the Voice context. You

- contain @code{Staff} contexts.
-
- @item @code{PianoStaff}@indexcode{PianoStaff}
- Just like @code{GrandStaff} but with @code{minVerticalAlign} set
- equal to @code{maxVerticalAlign} so that interstaff beaming and
- slurring can be used.
-
- @item @code{StaffGroup}@indexcode{StaffGroup}

- are not connected vertically.
-
- @item @code{Score}@indexcode{Score}
- This is the top level notation context. No other context can
- contain a @code{Score} context. This context handles the
- administration of time signatures. It also makes sure that items
- such as clefs, time signatures, and key-signatures are aligned
- across staffs. It can contain @code{Lyrics}, @code{Staff},
- @code{RhythmicStaff}, @code{GrandStaff}, @code{StaffGroup}, and
- @code{ChoirStaff} contexts.
-
- You cannot explicitly instantiate a Score context (since it is
- not contained in any other context). It is instantiated
- automatically when an output definition (a @code{\score} or
- @code{\paper} block) is processed.

-
-Properties that are set in one context are inherited by all of the
-contained contexts. This means that a property valid for the
-@code{Voice} context can be set in the @code{Score} context (for
-example) and thus take effect in all @code{Voice} contexts.
-
-Properties can be preset within the @code{\translator} block
-corresponding to the appropriate context. In this case, the syntax
-is
-
-@example
-
- @var{propname} @code{=} @var{value}
-@end example
-
-This assignment happens before interpretation starts, so a
-@code{\property} expression will override any predefined settings.
-
-The @code{\property} expression will create any property you specify.
-There is no guarantee that a property will be used. So if you spell
-a property name wrong, there will be no error message.
-
-The property settings are used during the interpretation phase. They
-are read by the LilyPond modules where interpretation contexts are
-built of. These modules are called @emph{translators}. Translators for
-notation are called @emph{engravers}, and translators for sound are
-called @emph{performers}.
-
-The precise result of a property is determined by the implementation
-of the translator that reads them. Therefore, the result of a
-property can vary, since it is implementation and configuration
-dependent.
-
-In order to fully find out what properties are used, you must
-currently search the source code for calls to @code{get_property}.

-
- @item @code{fontSize}@indexcode{fontSize}
- Can be used to select smaller font sizes for music. The normal
- font size is 0, and the two smaller sizes are -1

-
- @item @code{forceHorizontalShift}@indexcode{forceHorizontalShift}
- Force horizontal shift for collision resolution. It overrides
- automatic collision resolution. The value is the shift amount
- expressed in @code{note_width}, as set in the paper section.
-
-[FIXME: this should be moved]
-
-Lilypond always arranges note heads on alternate sides of a stem (that
-is, within a single voice) as necessary to prevent collisions (note head
-overlaps). For up stems, the upper note of a colliding pair is placed
-on the right side of the stem, the lower on the left. For down stems,
-the algorithm works in reverse.
-
-Lily also attempts to prevent collisions of note heads in different
-voices. A situation where chords of two or more voices are played
-simultaneously within one staff.
-
-By default, if only two voices (and both have opposite stem directions)
-are in this 'collision group', the notes both are shifted by @code{0.5
-\quartwidth} if there are unisons or seconds between the voices.
-
-If there are more than two voices in a collision group, shifting is
-inactive by default, since in this case, there are multiple chords with
-the same stem direction. By distinguish between those chords, LilyPond
-can do collision resolution in these cases as well.
-
-Distinguishing between voices with the same stem direction, is done by
-setting the property @code{Voice.horizontalNoteShift}. It must be set
-to a different integer for each voice. Then, all note heads in collision
-groups (not just unisons and seconds) will be offset, one voice relative
-another. The following fragment of sheet music shows how shifting is
-done, with values of @code{horizontalNoteShift} printed over and under
-the notes. In this case the chords are just simple notes.

-
-If you are not satisfied with the collision resolution of LilyPond, you
-can override the horizontal shift value of the chord of one Voice, by
-setting @code{forceHorizontalShift}. This sets the amount shift,
-measured in black note head widths.
-
-To take complete control of note position shifts in complex passages,
-you have set things up for normal collisions and override all shifts by
-setting @code{forceHorizontalShift} to zero everywhere
-@example
-\property Voice.horizontalNoteShift = <n>
-\property Voice.forceHorizontalShift = "0.0"
-@end example
-
-Then you can set the force property to a suitable value before each note
-that really needs it (unisons and seconds), and reset it to 0.0 after
-the note.
-
- @item @code{horizontalNoteShift}@indexcode{horizontalNoteShift}
- Enable LilyPond to shift notes horizontally if they collide with
- other notes. This is useful when typesetting many voices on one
- staff. The identifier @code{\shift}@keyindex{shift} is defined to
- enable this. Traditionally, the outer chords (the upmost and
- downmost voices), should have no @code{horizontalNoteShift}.
-
- @item @code{markScriptPadding}@indexcode{markScriptPadding}
- Determines the extra space added between the mark and the closest
- staff line or note.
-
- @item @code{markDirection}@indexcode{markDirection}

- Set to @code{\up} to print marks above the staff; set to
- @code{\down} to print marks below the staff.
-
- @item @code{midiInstrument}@indexcode{midiInstrument}
- Sets the instrument for MIDI output. If this property is not set
- then LilyPond will use the @code{instrument} property. This must
- be set to one of the strings on the list of MIDI instruments that
- appears in section XREF-midilist [FIXME]. If you use a string which
- is not listed, LilyPond will silently substitute piano.
-
- @item @code{oldTieBehavior}@indexcode{oldTieBehavior}
- Set to 1 in order to get old tie behavior where ties would
- connect unequal pitches. This property is deprecated, and its
- use is not recommended.
-
- @item @code{restStyle}@indexcode{restStyle}
- Change the layout of rests shorter than quarter notes.
- Currently, the standard layout @code{""} and mensural notation
- @code{"mensural"} are available. Mensural rests of duration
- 32 or shorter are not available.
-
- @item @code{scriptHorizontal}@indexcode{scriptHorizontal}
- Put scripts left or right of note heads. Support for this is
- limited. Accidentals will collide with scripts.
-
- @item @code{slurVerticalDirection}@indexcode{slurVerticalDirection}
- Set to @code{\free} for free choice of slur direction, set to
- @code{\up} to force slurs up, set to @code{\down} to force slurs
- down. The shorthands @code{\slurup}@keyindex{slurup},
- @code{\slurdown}@keyindex{slurdown}, and
- @code{\slurboth}@keyindex{slurboth} are available.
-
- @item @code{slurDash}@indexcode{slurDash}
- Set to 0 for normal slurs, 1 for dotted slurs, and a
- larger value for dashed slurs. Identifiers
- @code{\slurnormal}@keyindex{slurnormal} and
- @code{\slurdotted}@keyindex{slurdotted} are predefined to set the
- first two settings.
-
-@item @code{stemLength}@indexcode{stemLength}

- @code{stemLength} defaults to 7.
-
- @item @code{stemLeftBeamCount}@indexcode{stemLeftBeamCount}
- Specify the number of beams to draw on the left side of the next
- note. Overrides automatic beaming. The value is only used once,
- and then it is erased.
-
- @item @code{stemRightBeamCount}@indexcode{stemRightBeamCount}
- Specify the number of beams to draw on the right side of the next
- note. Overrides automatic beaming. The value is only used once,
- and then it is erased.
- @item @code{tieVerticalDirection}@indexcode{tieVerticalDirection}
- Set to @code{\free} for free choice of tie direction, set to
- @code{\up} to force ties up, set to @code{\down} to force ties
- down.
-
- @item @code{transposing}@indexcode{transposing}
- Transpose the MIDI output. Set this property to the number of
- half-steps to transpose by.

- Set the text style for superscripts and subscripts. See above
- for list of text styles.
-
- @item @code{textScriptPadding}@indexcode{textScriptPadding}
- Determines the extra space added between superscripted resp.
- subscripted text and the closest staff line or note.
-
- @item @code{verticalDirection}@indexcode{verticalDirection}
- Determines the direction of stems, subscripts, beams, slurs, and
- ties. Set to @code{\down} to force them down, @code{\up} to force
- them up, or @code{\free} to let LilyPond decide. This can be used
- to distinguish between voices on the same staff. The
- @code{\stemdown}@keyindex{stemdown}, @code{\stemup}@keyindex{stemup},
- and @code{\stemboth}@keyindex{stemboth} identifiers set this
- property.
-
-
- @item @code{tupletDirection}@indexcode{tupletDirection}
- Determines the direction of triplets and other tuplets. Set to
- @code{\down} to force them below the staff, @code{\up} to force
- them above, or @code{\free} to let LilyPond decide.
-
- @item @code{tupletVisibility}@indexcode{tupletVisibility}
- Determines whether tuplets of notes are labelled. Setting
- to 0 shows nothing; setting to 1 shows a number;
- setting to 2 shows a number and a bracket if there is no
- beam; setting to 3 shows a number, and if there is no beam
- it adds a bracket; setting to 4 shows both a number and a
- bracket unconditionally.

-
-The most important output definition is the @code{\paper} block, for
-music notation. The syntax is
-
-@example
-
- @code{\paper @{} [@var{paperidentifier}] @var{items} @code{@}}
-@end example
-
-where each of the items is one of
-
-@itemize @bullet
- @item An assignment. The assignment must be terminated by a
- semicolon. See section XREF-papervars [FIXME] for information on
- paper variables.
-
- @item A context definition. See section XREF-contextdefs [FIXME] for
- more information on context definitions.
-
- @item A margin shape declaration. The syntax is
-
- @example
-
- \shape @var{indent1}@code{,} @var{width1}@code{,}
- @var{indent2}@code{,} @var{width2} @dots{} @code{;}
- @end example
-
- @keyindex{shape}
-
- Each pair of @var{indent} and @var{width} values is a dimension
- specifying how far to indent and how wide to make the line.
- The indentation and width of successive lines are specified by
- the successive pairs of dimensions. The last pair of
- dimensions will define the characeristics of all lines beyond
- those explicitly specified.
-
- @item A font declaration. Its syntax is
-
- @example
-
- @var{fontsize} @code{=} \font@keyindex{font} @var{fontname}
- @end example
-
- @var{fontsize} is an integer describing the font to be used.
- 0 is the default font. @var{fontname} is the basename of
- a font (usually a member of the Feta family).
-@end itemize
-
-
-
-@cindex changing font size and paper size
-
-The Feta font provides musical symbols at six different sizes. These
-fonts are 11 point, 13 point, 16 point, 20 point,
-23 point, and 26 point. The point size of a font is the
-height of the five lines in a staff when displayed in the font.
-
-Definitions for these sizes are the files @file{paperSZ.ly}, where
-@code{SZ} is one of 11, 13, 16, 20, 23 and 26. If you include
-any of these files, the identifiers @code{paper_eleven},
-@code{paper_thirteen}, @code{paper_sixteen}, @code{paper_twenty},
-@code{paper_twentythree}, and @code{paper_twentysix} are defined
-respectively. The default @code{\paper} block is also set.
-
-To change the paper size, you must first set the
-@code{papersize}@indexcode{papersize} variable at top level. Set it to the strings
-@code{a4}, @code{letter}, or @code{legal}. After this specification,
-you must set the font as described above. If you want the default
-font, then use the 20 point font. The new paper size will not
-take effect if the font is not loaded and selected afterwards. Paper
-size selection works by loading a file named after the paper size you
-select.
-
-
-
-@cindex paper variables
-
-@node papervars, , , Reference Manual
-
-There is a large number of paper variables that are used to control
-details of the layout. These variables control the defaults for the
-entire score. Usually, they do not have to be changed; they are by
-default set to values that depend on the font size in use. The
-values are used by the graphic objects while formatting the score;
-they are therefore implementation dependent. Most variables are
-accompanied by documentation in the initalization file
-@file{params.ly} or @file{paperSZ.ly}, where @code{SZ} is the staff
-height in points.
-
-Nevertheless, here are some variables you may want to use or change:
-
-@table @samp
- @item @code{indent}@indexcode{indent}
- The indentation of the first line of music.
-
- @item @code{interline}@indexcode{interline}
- The distance between two staff lines, calculated from the center
- of the lines. You should use either this or @code{rulethickness}
- as a unit for distances you modify.
-
- @item @code{linewidth}@indexcode{linewidth}
- Sets the width of the lines. If set to -1.0, a single
- unjustified line is produced.
-
- @item @code{output}@indexcode{output}
- Specifies an alternate name for the the output @file{s}.
- A @file{.tex}, @file{.midi} or @file{.ps} extension will be
- added to the string you specify.
-
- @item @code{rulethickness}@indexcode{rulethickness}
- Determines the thickness of staff and bar lines.
-
- @item @code{castingalgorithm}@indexcode{castingalgorithm}
- The algorithm to use for breaking lines. Choices are
- @code{\Gourlay}@keyindex{Gourlay} for a TeX-like dynamic
- programming algorithm, and @code{\Wordwrap}@keyindex{Wordwrap} for
- a simple algorithm. Gourlay breaking looks much better, but
- takes a lot more resources. Wordwrap leaves loosely spaced lines
- at the end.
