\dropNote num (integer) music (music) ⇒ music ¶

‘Drop’ the num-th note in each chord of music.

This function moves the affected notes down (usually by an octave) to be lower than the other notes of the chord. The position in a chord is counted downwards from the top.

The opposite function is \raiseNote.

\enablePolymeter ⇒ void ¶

This function moves the timing management from Score to Staff-like contexts. This is done by removing the Timing_translator from Score, and adding it to all contexts having the Staff alias.

Use this within an output definition.

\endSpanners music (music) ⇒ music ¶

Terminate spanners.

This function prematurely ends all spanners in music by inserting an end-spanner event at the end of the argument, without the need of specific end-spanner commands.

\footnote [mark (markup)] offset (pair of numbers) footnote (markup) item (symbol list or music) ⇒ music ¶

Make the markup footnote a footnote on item.

The footnote is marked with a markup mark moved by offset with respect to the marked music.

If mark is not given or specified as \default, it is replaced by an automatically generated sequence number. If item is a symbol list of form Grob or Context.Grob, then grobs of that type are marked at the current time step in the given context (default Bottom).

If item is music, the music gets a footnote attached to a grob immediately attached to the event, like \tweak does. For attaching a footnote to an indirectly caused grob, write \single\footnote, use item to specify the grob, and follow it with the music to annotate.

Like with \tweak, if you use a footnote on a following post-event, the \footnote command itself needs to be attached to the preceding note or rest as a post-event with ‘-’.

\glide fingering (music) ⇒ post-event ¶

Take a fingering-event and create a FingerGlideEvent setting the digit property. If the fingering-event has a tweak for id it as applied to the FingerGlideEvent as well. Both events are returned in PostEvents.

This prints a warning if the interval between the previous note and pitch is not within a fourth.

\offset property (symbol list or symbol) offsets (any type) item (key list or music) ⇒ music ¶

Offset the default value of property of item by offsets.

If item is a string, the result is an override for the specified grob type. If item is a music expression, the result is the same music expression with an appropriate tweak applied to it.

\omit item (symbol list or music) ⇒ music ¶

Omit item without taking up space.

If item is a symbol list of form GrobName or Context.GrobName, the result is an override for the grob name specified by it. If item is a music expression, the result is the same music expression with an appropriate tweak applied to it.

This function sets item’s stencil property to #f.

\once music (music) ⇒ music ¶

Set property once to #t on all layout instruction events in music.

\ottava octave (integer) ⇒ music ¶

A positive value n indicates n octaves higher; a negative value n octaves lower, and value 0 means no octavation.

\overrideProperty grob-property-path (list of indices or symbols) value (any type) ⇒ music ¶

Set the grob property specified by grob-property-path to value.

grob-property-path is a symbol list of the form Context.GrobName.property or GrobName.property, possibly with subproperties given as well.

As opposed to \override, which overrides the context-dependent defaults with which a grob is created, this command uses Output_property_engraver at the grob acknowledge stage. This may be necessary for overriding values set after the initial grob creation.

\overrideTimeSignatureSettings time-signature (boolean-or-fraction) base-moment (positive exact rational, fraction (as pair), moment, or +inf.0) beat-structure (list) beam-exceptions (list) ⇒ music ¶

Within music, parallel music sequences are separated by ‘|’ characters. The sequences are assigned to the LilyPond music identifiers provided in voice-ids.

For example, this code

\parallelMusic A,B,C {
  c c | d d | e e |
  d d | e e | f f |
}

is equivalent to

A = { c c | d d }
B = { d d | e e }
C = { e e | f f }

The last bar checks in a sequence are not copied to the result in order to facilitate ending the last entry at non-bar boundaries.

\parenthesize arg (symbol list or music) ⇒ music ¶

Tag arg to be parenthesized.

arg may be either a music event or a grob path.

\partCombine [chord-range (pair of numbers)] part1 (music) part2 (music) ⇒ music ¶

Combine two parts into a single staff.

This takes the music in part1 and part2 and returns a music expression containing simultaneous Voice contexts (called one for the upper and two for the lower voice). Where appropriate, part1 and part2 are combined into a single voice (called shared or solo, depending on context).

Optional argument chord-range is a pair (start . stop) that defines the range in which the two voices are printed as chords (or unison); the default value is (0 . 8), which means that intervals up to and including a ninth are unified.

\partCombineDown [chord-range (pair of numbers)] part1 (music) part2 (music) ⇒ music ¶

Combine two parts into a single staff with all stems downwards.

See function \partCombine for details.

\partCombineForce [type (symbol)] ⇒ music ¶

See function \partCombine for details.

\partial dur (duration) ⇒ music ¶

Make a partial measure of duration dur.

\phrasingSlurDashPattern dash-fraction (number) dash-period (number) ⇒ music ¶

Set up a custom dash pattern style for phrasing slurs.

dash-fraction gives the size of one dash relative to dash-period; dash-period is the length of one dash plus one space. LilyPond adjusts dash-period to produce symmetrical output.

More complex patterns can be achieved by directly manipulating the PhrasingSlur.dash-definition property.

\pitchedTrill main-note (music) secondary-note (music) ⇒ music ¶

Print a pitched trill.

main-note is the main note of the trill; secondary-note gets printed as a stemless note head in parentheses.

\pointAndClickOff ⇒ void ¶

Suppress links to LilyPond source code in music output.

\pointAndClickOn ⇒ void ¶

Generate links to LilyPond source code in music output.

This enables the creation of code in a PDF or SVG output file to reference the originating LilyPond source code (i.e., file name, line number, and column). This is helpful when developing a score; however, the output file becomes much larger.

\pointAndClickTypes types (symbol list or symbol) ⇒ void ¶

Generate point-and-click info for music of type types only.

types is a single music expression (such as #'note-event) or a list of music expressions.

\popContextProperty path (list of indices or symbols) ⇒ music ¶

Set BendSpanner.style to 'pre-bend-hold for mus.

\propertyOverride grob-property-path (list of indices or symbols) value (any type) ⇒ music ¶

Set the grob property specified by grob-property-path to value.

grob-property-path is a symbol list of the form Context.GrobName.property or GrobName.property, possibly with subproperties given as well. This music function is mostly intended for use from Scheme as a substitute for the built-in \override command.

\propertyRevert grob-property-path (list of indices or symbols) ⇒ music ¶

Revert the grob property specified by grob-property-path to its previous value.

grob-property-path is a symbol list of the form Context.GrobName.property or GrobName.property, possibly with subproperties given as well. This music function is mostly intended for use from Scheme as a substitute for the built-in \revert command.

\propertySet property-path (symbol list or symbol) value (any type) ⇒ music ¶

Set the context property specified by property-path to value.

This music function is mostly intended for use from Scheme as a substitute for the built-in \set command.

\propertyTweak prop (key list or symbol) value (any type) item (key list or music) ⇒ music ¶

Add a tweak to item, usually music.

This function sets the value of property prop to value; it generally behaves like \tweak but will turn into an \override when item is a symbol list. In that case, item specifies the grob path to override. This is mainly useful when using \propertyTweak as as a component for building other functions like \omit. It is not the default behavior for \tweak since many input strings in \lyricmode can serve equally as music or as symbols, which causes surprising behavior when tweaking lyrics using the less specific semantics of \propertyTweak.

prop can contain additional elements in which case a nested property (inside of an alist) is tweaked.

\propertyUnset property-path (symbol list or symbol) ⇒ music ¶

Unset the context property specified by property-path.

This music function is mostly intended for use from Scheme as a substitute for the built-in \unset command.

The old value can be popped off the stack and restored with function \popContextProperty.

\pushToTag tag (symbol) more (music) music (music) ⇒ music ¶

Add more to the front of music tagged with tag.

A post-event can be added to the articulations of rhythmic events or chords; other expressions may be added to chords, sequential or simultaneous music.

\quoteDuring what (string) main-music (music) ⇒ music ¶

Indicate a section of music to be quoted.

what indicates the name of the quoted voice, as specified in an \addQuote command. main-music is used to indicate the length of music to be quoted; it usually contains spacers or multi-measure rests.

\raiseNote num (integer) music (music) ⇒ music ¶

‘Raise’ the num-th note in each chord of music.

This function moves the affected notes up (usually by an octave) to be higher than the other notes of the chord. The position in a chord is counted upwards from the bottom.

The opposite function is \dropNote.

\reduceChords music (music) ⇒ music ¶

Reduce chords contained in music to single notes.

This is intended mainly for reusing music in a RhythmicStaff context. It does not reduce simultaneous music.

\relative [pitch (pitch)] music (music) ⇒ music ¶

Make music relative to pitch.

If pitch is omitted, the first note in music is given in absolute pitch.

\removeWithTag tags (symbol list or symbol) music (music) ⇒ music ¶

Multiply the duration of events in music by fraction.

\sectionLabel text (markup) ⇒ music ¶

Mark the beginning of a named passage with text, e.g., “Coda”.

This is well suited for use at a section division created with \section, but it does not imply \section and may be used alone.

\segnoMark [num (non-negative, exact integer)] ⇒ music ¶

Create a segno mark (or bar line).

num may be 1 for the first segno, 2 for the second, etc., or it may be \default to use the next number in sequence automatically.

If the segnoStyle context property is 'bar-line, a segno bar line is created instead of a segno mark.

\settingsFrom [ctx (symbol)] music (music) ⇒ any type ¶

Translate layout instructions into a context modification.

This function takes the layout instruction events from music (i.e., \set, \unset, \override, \revert), optionally restricted to those applying to context type ctx, and returns a context modification duplicating their effect.

\shape offsets (list) item (key list or music) ⇒ music ¶

Offset control points of item by offsets.

offsets is a list of number pairs (x . y) or a list of such lists. Each pair represents an offset to a control point. The ‘y’ value of each pair is scaled by staff space.

If item is a string, the result is \once\override for the specified grob type. If item is a music expression, the result is the same music expression with an appropriate tweak applied.

\shiftDurations dur (integer) dots (integer) arg (music) ⇒ music ¶

Set up a custom dash pattern style for slurs.

dash-fraction gives the size of one dash relative to dash-period; dash-period is the length of one dash plus one space. LilyPond adjusts dash-period to produce symmetrical output.

More complex patterns can be achieved by directly manipulating the Slur.dash-definition property.

\staffHighlight color (color) ⇒ music ¶

Start a highlight with color color.

\storePredefinedDiagram fretboard-table (hash table) chord (music) tuning (pair) diagram-definition (string or pair) ⇒ void ¶

\tabChordRepetition ⇒ void ¶

Include the string and fingering information in a chord repetition.

This function is deprecated; use \tabChordRepeats instead.

\tag tags (symbol list or symbol) music (music) ⇒ music ¶

Tag music with tags.

This function adds the single symbol or symbol list tags to the tags property of music and returns the result.

\tagGroup tags (symbol list) ⇒ void ¶

Define a tag group comprising the symbols in the symbol list tags.

Tag groups must not overlap.

\temporary music (music) ⇒ music ¶

Make \override reversible with \revert.

This function makes any \override in music replace an existing grob property value only temporarily, restoring the old value when a corresponding \revert is executed. This is achieved by clearing the pop-first property normally set on \overrides.

An \override/\revert sequence created by using \temporary and \undo on the same music containing overrides will cancel out perfectly or cause a warning.

Non-property-related music is ignored, warnings are generated for any property-changing music that isn’t an \override.

\textEndMark text (markup) ⇒ music ¶

Create a right-aligned text mark using text.

\textMark text (markup) ⇒ music ¶

Create a (left-aligned) text mark using text.

\tieDashPattern dash-fraction (number) dash-period (number) ⇒ music ¶

Set up a custom dash pattern style for ties.

dash-fraction gives the size of one dash relative to dash-period; dash-period is the length of one dash plus one space. LilyPond adjusts dash-period to produce symmetrical output.

More complex patterns can be achieved by directly manipulating the Tie.dash-definition property.

\time [beat-structure (number list)] fraction (fraction, as pair) ⇒ music ¶

Set fraction as a time signature.

The optional number list beat-structure additionally sets a beat structure.

\times fraction (fraction, as pair) music (music) ⇒ music ¶

Scale music in time by fraction.

\tocItem [label (symbol list or symbol)] text (markup) ⇒ music ¶

Add text as an entry to the table of contents.

This uses the tocItemMarkup paper variable markup for formatting and assigns it to label if one is provided. If a hierarchy of labels is given, make the current item a child of the corresponding objects.

\transpose from (pitch) to (pitch) music (music) ⇒ music ¶

Transpose music from pitch from to pitch to.

\transposedCueDuring what (string) dir (direction) pitch (pitch) main-music (music) ⇒ music ¶

Create a transposed cue.

This function inserts notes from the part what into a CueVoice context called cue, using the transposition defined by pitch. This happens simultaneously with main-music, which is usually a rest. The argument dir determines whether the cue notes should be notated as a first or second voice.

\transposition pitch (pitch) ⇒ music ¶

Set instrument transposition to pitch.

\tuplet ratio (fraction, as pair) [tuplet-span (duration)] music (music) ⇒ music ¶

Scale the given music to tuplets.

ratio is a fraction that specifies how many notes are played in place of the nominal value: it will be 3/2 for triplets, namely three notes being played in place of two.

If the optional duration tuplet-span is specified, it is used instead of tupletSpannerDuration for grouping the tuplets. For example,

\tuplet 3/2 4 { c8 c c c c c }

results in two groups of three tuplets, each group lasting for a quarter note.

\tupletSpan [tuplet-span (duration)] ⇒ music ¶

Set tupletSpannerDuration to the duration tuplet-span.

This context property is the length into which \tuplet without an explicit tuplet span argument of its own will group its tuplets. To revert to the default of not subdividing the contents of a \tuplet command without an explicit tuplet span argument, use

\tupletSpan \default

\tweak prop (key list or symbol) value (any type) music (music) ⇒ music ¶

Add a tweak to music.

Layout objects created by music get their property prop set to value. If prop has the form Grob.property, like with

\tweak Accidental.color #red cis'

an indirectly created grob (Accidental is caused by NoteHead) can be tweaked; otherwise only directly created grobs are affected.

prop can contain additional elements in which case a nested property (inside of an alist) is tweaked.

If music is an event-chord, every contained rhythmic-event is tweaked instead.

\undo music (music) ⇒ music ¶

Convert \override and \set in music to \revert and \unset, respectively.

Any reverts and unsets already in music cause a warning. Non-property-related music is ignored.

\unfolded music (music) ⇒ music ¶

Mask music until the innermost enclosing repeat is unfolded.

\unfoldRepeats [types (symbol list or symbol)] music (music) ⇒ music ¶

Unfold \repeat.

This forces \repeat volta, \repeat tremolo or \repeat percent commands in music to be interpreted as \repeat unfold, if specified in the optional symbol-list types. The default for types is an empty list, which forces any of those commands in music to be interpreted as \repeat unfold. Possible entries are volta, tremolo or percent. Multiple entries are possible.

\versus music (music) ⇒ music ¶

Prepend character U+2123 (VERSICLE) to the lyrics represented by music.

\voices ids (list of indices or symbols) music (music) ⇒ music ¶

Specify voice order in simultaneous music.

This takes the key list ids of numbers (indicating the use of ‘\voiceOne’…) or symbols (indicating voice names, typically converted from strings by argument list processing) and assign the following \\-separated music in music to contexts according to that list. Named rather than numbered contexts can be used for continuing one voice (for the sake of spanners and lyrics), usually requiring a \voiceOne-style override at the beginning of the passage and a \oneVoice override at its end.

The default

<< … \\ … \\ … >>

construct would correspond to

\voices 1,2,3 << … \\ … \\ … >>

\void arg (any type) ⇒ void ¶

Accept a Scheme argument arg and return a void expression.

Use this if you want to have a Scheme expression evaluated because of its side effects but its return value being ignored.

\volta volta-numbers (number list) music (music) ⇒ music ¶

Mark music as being limited to the volte given in volta-numbers.

This gets used when the innermost enclosing repeat is unfolded. Volta number begins at 1 and increases by 1 with each repetition.

\vshape offsets (list) item (key list or music) ⇒ music ¶

Like \shape, but additionally show control points for ease of tweaking.

\withMusicProperty sym (symbol) val (any type) music (music) ⇒ music ¶

Set music property sym to val in music.

\withRelativeDir file-name (string) ⇒ any type ¶

Prepend directory of current input file to string file-name.

Use this for markup commands that include files, and where such files should be found relative to the input file. Example:

\markup { \image #X #3 \withRelativeDir "test.png" }

\xNote note (music) ⇒ music ¶

Print note with a cross-shaped note head.

\= id (index or symbol) event (post-event) ⇒ post-event ¶

Assign an ID to a spanner or an item.

This sets the spanner-id or id property of event to the given id, which is a non-negative integer or a symbol.

For spanners this can be used to tell LilyPond how to connect overlapping or parallel slurs or phrasing slurs within a single Voice context.

\fixed c' { c\=1( d\=2( e\=1) f\=2) }

For itmes this can be used, for example, to tell LilyPond how to connect a FingerGlideSpanner with non-matching fingers.

\fixed c' { c\glide \= #'foo -1 d\= #'foo -2 }
