1.6 Staff notation

This section explains how to influence the appearance of staves, how to print scores with more than one staff, and how to add tempo indications and cue notes to staves.

1.6.1 Displaying staves

This section describes the different methods of creating and grouping staves.

Instantiating new staves

Staves (singular: staff) are created with the \new or \context commands. For details, see Creating and referencing contexts.

The basic staff context is Staff:

\new Staff \relative { c''4 d e f }

The DrumStaff context creates a five-line staff set up for a typical drum set. Each instrument is shown with a different symbol. The instruments are entered in drum mode following a \drummode command, with each instrument specified by name. For details, see Percussion staves.

\new DrumStaff { \drummode { cymc hh ss tomh } }

RhythmicStaff creates a single-line staff that only displays the rhythmic values of the input. Real durations are preserved. For details, see Showing melody rhythms.

\new RhythmicStaff { c4 d e f }

TabStaff creates a tablature with six strings in standard guitar tuning. For details, see Default tablatures.

\new TabStaff \relative { c''4 d e f }

There are two staff contexts specific for the notation of ancient music: MensuralStaff and VaticanaStaff. They are described in Pre-defined contexts.

The GregorianTranscriptionStaff context creates a staff to notate modern Gregorian chant. It does not show bar lines.

\new GregorianTranscriptionStaff \relative { c''4 d e f e d }

New single staff contexts may be defined. For details, see Defining new contexts.

Grouping staves

Various contexts exist to group single staves together in order to form multi-staff systems. Each grouping context sets the style of the system start delimiter and the behavior of bar lines.

If no context is specified, the default properties will be used: the group is started with a vertical line, and the bar lines are not connected.

<< \new Staff \relative { c''1 c } \new Staff \relative { c''1 c } >>

In the StaffGroup context, the group is started with a bracket and bar lines are drawn through all the staves.

\new StaffGroup << \new Staff \relative { c''1 c } \new Staff \relative { c''1 c } >>

In a ChoirStaff, the group starts with a bracket, but bar lines are not connected.

\new ChoirStaff << \new Staff \relative { c''1 c } \new Staff \relative { c''1 c } >>

In a GrandStaff, the group begins with a brace, and bar lines are connected between the staves.

\new GrandStaff << \new Staff \relative { c''1 c } \new Staff \relative { c''1 c } >>

The PianoStaff is identical to a GrandStaff, except that it supports printing the instrument name directly. For details, see Instrument names.

\new PianoStaff \with { instrumentName = "Piano" } << \new Staff \relative { c''1 c } \new Staff \relative { \clef bass c1 c } >>

Each staff group context sets the property systemStartDelimiter to one of the following values: SystemStartBar, SystemStartBrace, or SystemStartBracket. A fourth delimiter, SystemStartSquare, is also available, but it must be explicitly specified.

New staff group contexts may be defined. For details, see Defining new contexts.

Selected Snippets

Use square bracket at the start of a staff group

The system start delimiter SystemStartSquare can be used by setting it explicitly in a StaffGroup or ChoirStaff context.

\score { \new StaffGroup { << \set StaffGroup.systemStartDelimiter = #'SystemStartSquare \new Staff { c'4 d' e' f' } \new Staff { c'4 d' e' f' } >> } }

Display bracket with only one staff in a system

If there is only one staff in one of the staff types ChoirStaff or StaffGroup, by default the bracket and the starting bar line will not be displayed. This can be changed by overriding collapse-height to set its value to be less than the number of staff lines in the staff.

Note that in contexts such as PianoStaff and GrandStaff where the systems begin with a brace instead of a bracket, another property has to be set, as shown on the second system in the example.

\score { \new StaffGroup << % Must be lower than the actual number of staff lines \override StaffGroup.SystemStartBracket.collapse-height = #4 \override Score.SystemStartBar.collapse-height = #4 \new Staff { c'1 } >> } \score { \new PianoStaff << \override PianoStaff.SystemStartBrace.collapse-height = #4 \override Score.SystemStartBar.collapse-height = #4 \new Staff { c'1 } >> }

Mensurstriche layout (bar lines between the staves)

The mensurstriche-layout where the bar lines do not show on the staves but between staves can be achieved with a StaffGroup instead of a ChoirStaff. The bar line on staves is blanked out using \hide.

global = { \hide Staff.BarLine s1 s % the final bar line is not interrupted \undo \hide Staff.BarLine \bar "|." } \new StaffGroup \relative c'' { << \new Staff { << \global { c1 c } >> } \new Staff { << \global { c c } >> } >> }

Nested staff groups

Staff-group contexts can be nested to arbitrary depths. In this case, each child context creates a new bracket adjacent to the bracket of its parent group.

\new StaffGroup << \new Staff \relative { c''2 c | c2 c } \new StaffGroup << \new Staff \relative { g'2 g | g2 g } \new StaffGroup \with { systemStartDelimiter = #'SystemStartSquare } << \new Staff \relative { e'2 e | e2 e } \new Staff \relative { c'2 c | c2 c } >> >> >>

New nested staff group contexts can be defined. For details, see Defining new contexts.

Selected Snippets

Nesting staves

The property systemStartDelimiterHierarchy can be used to make more complex nested staff groups. The command \set StaffGroup.systemStartDelimiterHierarchy takes an alphabetical list of the number of staves produced. Before each staff a system start delimiter can be given. It has to be enclosed in brackets and takes as much staves as the brackets enclose. Elements in the list can be omitted, but the first bracket takes always the complete number of staves. The possibilities are SystemStartBar, SystemStartBracket, SystemStartBrace, and SystemStartSquare.

\new StaffGroup \relative c'' << \override StaffGroup.SystemStartSquare.collapse-height = #4 \set StaffGroup.systemStartDelimiterHierarchy = #'(SystemStartSquare (SystemStartBrace (SystemStartBracket a (SystemStartSquare b) ) c ) d) \new Staff { c1 } \new Staff { c1 } \new Staff { c1 } \new Staff { c1 } \new Staff { c1 } >>

Separating systems

If the number of systems per page changes from page to page it is customary to separate the systems by placing a system separator mark between them. By default the system separator is blank, but can be turned on with a \paper option.

\book { \score { \new StaffGroup << \new Staff { \relative { c''4 c c c \break c4 c c c } } \new Staff { \relative { c''4 c c c \break c4 c c c } } >> } \paper { system-separator-markup = \slashSeparator % following commands are needed only to format this documentation paper-width = 100\mm paper-height = 100\mm tagline = ##f } }

1.6.2 Modifying single staves

This section explains how to change specific attributes of one staff: for example, modifying the number of staff lines or the staff size. Methods to start and stop staves and set ossia sections are also described.

Staff symbol

The \stopStaff and \startStaff commands can be used to stop or (re)start the staff lines respectively, from being printed at any point witin a score.

\relative { \stopStaff f''4 d \startStaff g, e f'4 d \stopStaff g, e f'4 d \startStaff g, e }

Predefined commands

\startStaff, \stopStaff.

The lines of a staff belong to the StaffSymbol grob (including ledger lines) and can be modified using StaffSymbol properties, but these modifications must be made before the staff is (re)started.

The number of staff lines can be altered:

\relative { f''4 d \stopStaff \override Staff.StaffSymbol.line-count = #2 \startStaff g, e | f'4 d \stopStaff \revert Staff.StaffSymbol.line-count \startStaff g, e | }

The position of each staff line can also be altered. A list of numbers sets each line’s position. 0 corresponds to the normal center line, and the normal line positions are (-4 -2 0 2 4). A single staff line is printed for every value entered so that the number of staff lines, as well as their position, can be changed with a single override.

\relative { f''4 d \stopStaff \override Staff.StaffSymbol.line-positions = #'(1 3 5 -1 -3) \startStaff g, e | f'4 d \stopStaff \override Staff.StaffSymbol.line-positions = #'(8 6.5 -6 -8 -0.5) \startStaff g, e | }

To preserve typical stem directions (in the bottom half of the staff stems point up, in the top half they point down), align the center line (or space) of the customized staff with the position of the normal center line (0). The clef position and the position of middle C may need to be adjusted accordingly to fit the new lines. See Clef.

Staff line thickness can be altered. Ledger lines and note stems, by default, are also affected.

\new Staff \with { \override StaffSymbol.thickness = #3 } \relative { f''4 d g, e }

It is also possible to set ledger line thickness independently of staff lines.

\new Staff \with { \override StaffSymbol.thickness = #2 \override StaffSymbol.ledger-line-thickness = #'(0.5 . 0.4) } \relative { f'''4 a, a,, f }

The first value is multiplied by the staff line thickness, the second by the staff space and then the two values are added together to give the new thickness of the ledger line.

The vertical positions of ledger lines can be altered,

\new Staff \with { \override StaffSymbol.ledger-positions = #'(-3 -2 -1 2 5 6) } \relative { f'''4 a, a,, f }

Additional ledger lines can be made to appear above or below note heads depending on the current position relative to other note heads that also have their own ledger lines.

\new Staff \with { \override StaffSymbol.ledger-extra = #4 } \relative { f'''4 a, d, f, }

Ledger lines can also be made to appear inside the staff where custom staff lines are required. The example shows the default position of ledger lines when the explicit ledger-position is and is not set. The \stopStaff is needed in the example to revert the \override for the whole StaffSymbol.

\relative d' { \override Staff.StaffSymbol.line-positions = #'(-8 0 2 4) d4 e f g \stopStaff \startStaff \override Staff.StaffSymbol.ledger-positions = #'(-8 -6 (-4 -2) 0) d4 e f g }

The distance between staff lines can be altered. This affects ledger line spacing as well.

\new Staff \with { \override StaffSymbol.staff-space = #1.5 } \relative { f'''4 d, g, e, }

Selected Snippets

Making some staff lines thicker than the others

For educational purposes, a staff line can be thickened (e.g., the middle line, or to emphasize the line of the G clef). This can be achieved by adding extra lines very close to the line that should be emphasized, using the line-positions property of the StaffSymbol object.

{ \override Staff.StaffSymbol.line-positions = #'(-4 -2 -0.2 0 0.2 2 4) d'4 e' f' g' }

Ossia staves

Ossia staves can be set by creating a new simultaneous staff in the appropriate location:

\new Staff \relative { c''4 b d c << { c4 b d c } \new Staff { e4 d f e } >> c4 b c2 }

However, the above example is not what is usually desired. To create ossia staves that are above the original staff, have no time signature or clef, and have a smaller font size, tweaks must be used. The Learning Manual describes a specific technique to achieve this goal, beginning with (learning)Nesting music expressions section ‘Nesting music expressions’ in Learning Manual.

The following example uses the alignAboveContext property to align the ossia staff. This method is most appropriate when only a few ossia staves are needed.

\new Staff = "main" \relative { c''4 b d c << { c4 b d c } \new Staff \with { \remove "Time_signature_engraver" alignAboveContext = "main" \magnifyStaff #2/3 firstClef = ##f } { e4 d f e } >> c4 b c2 }

If many isolated ossia staves are needed, creating an empty Staff context with a specific context id may be more appropriate; the ossia staves may then be created by calling this context and using \startStaff and \stopStaff at the desired locations. The benefits of this method are more apparent if the piece is longer than the following example.

<< \new Staff = "ossia" \with { \remove "Time_signature_engraver" \hide Clef \magnifyStaff #2/3 } { \stopStaff s1*6 } \new Staff \relative { c'4 b c2 << { e4 f e2 } \context Staff = "ossia" { \startStaff e4 g8 f e2 \stopStaff } >> g4 a g2 \break c4 b c2 << { g4 a g2 } \context Staff = "ossia" { \startStaff g4 e8 f g2 \stopStaff } >> e4 d c2 } >>

Using the \RemoveAllEmptyStaves command to create ossia staves may be used as an alternative. This method is most convenient when ossia staves occur immediately following a line break. For more information about \RemoveAllEmptyStaves, see Hiding staves.

<< \new Staff = "ossia" \with { \remove "Time_signature_engraver" \hide Clef \magnifyStaff #2/3 \RemoveAllEmptyStaves } \relative { R1*3 c''4 e8 d c2 } \new Staff \relative { c'4 b c2 e4 f e2 g4 a g2 \break c4 b c2 g4 a g2 e4 d c2 } >>

Vertically aligning ossias and lyrics

This snippet demonstrates the use of the context properties alignBelowContext and alignAboveContext to control the positioning of lyrics and ossias.

Hiding staves

Staff lines can be hidden by removing the Staff_symbol_engraver from the Staff context. As an alternative, \stopStaff may be used.

\new Staff \with { \remove "Staff_symbol_engraver" } \relative { a''8 f e16 d c b a2 }

Empty staves can be hidden (for a so-called ‘Frenched Score’) by applying the \RemoveEmptyStaves command on a context, which can be done globally (in a \layout block) as well as for specific staves only (in a \with block). This command removes all empty staves in a score except for those in the first system. If you want those in the first system to be hidden also, use \RemoveAllEmptyStaves.

\layout { \context { \Staff \RemoveEmptyStaves } } \relative << \new Staff { e'4 f g a \break b1 \break a4 b c2 } \new Staff { c,4 d e f \break R1 \break f4 g c,2 } >>

A staff is considered empty when it contains only multi-measure rests, rests, skips, or a combination of these elements. All other musical objects (that cause a staff not to be considered as empty) are listed in the keepAliveInterfaces context property, as initially set in the ‘ly/engraver-init.ly’ file.

\RemoveEmptyStaves and \RemoveAllEmptyStaves are both predefined shortcuts that set such properties as remove-empty and remove-first for the VerticalAxisGroup object, as explained in Context modification identifiers.

The Keep_alive_together_engraver allows groups of staves to only be removed together and not individually. By default, it is part of the PianoStaff context: a piano part will only be hidden when both of its staves are empty. Similarly, a common engraving practice in orchestral scores is to remove empty groups of staves rather than individual staves; that can be achieved by adding the Keep_alive_together_engraver to the relevant staff-grouping context, as explained Modifying context plug-ins (see Grouping staves for the context names).

\layout {
  \context {
    \StaffGroup
    \RemoveEmptyStaves
    \consists "Keep_alive_together_engraver"
  }
}

In the following example, staves devoted to wind instruments are removed in the second system; however, the double bass is not, because it is part of the larger group of fretted strings, which is playing.

The Keep_alive_together_engraver internally uses the remove-layer property of a staff’s VerticalAxisGroup to decide whether to print it or not when it is considered empty. That property may also be set directly, in which case it acts as a priority index: values closest to zero take precedence over higher numbers, and thus staves whose remove-layer is higher will be masked in favor of staves of a lower number.

This is particularly useful for ‘divisi’ staves, where some individual parts (see Writing parts) occasionally need to be expanded to more than one staff. In the following example, two parts are routed to three staves; however, all three staves are never printed at the same time:

• in the first systems, only a single one of them is shown, as the keepAliveInterfaces property has been set to an empty list – therefore the other two staves are considered empty and thus hidden, regardless of what they may contain;
• when that property gets unset (and thus reverts to its default setting), it is no longer preventing the two other staves from being printed; however, as their remove-layer setting is lower than the single staff’s, these two staves are now printed in its place.

Such substitutions are applied not just to notes, chords and other musical events that occur immediately after the new setting, but to the whole system where it takes place.

\layout {
  short-indent = 2\cm
  indent = 3\cm
  \context {
    \Staff
    keepAliveInterfaces = #'()
  }
}

violI = {
  \repeat unfold 24 { d'4 }
  \once \unset Staff.keepAliveInterfaces
  <d' g''>2
  \repeat unfold 14 { d'4 }
  \bar "|."
}

violII = {
  \repeat unfold 24 { g4 }
  <g d'>2
  \repeat unfold 14 { g4 }
  \bar "|."
}

\new StaffGroup \with { \consists "Keep_alive_together_engraver" } <<
  \new Staff \with {
    instrumentName = "Violins"
    shortInstrumentName = "V I & II"
    \override VerticalAxisGroup.remove-layer = 2
  } <<  \violI \\ \violII  >>
  \new Staff \with {
    instrumentName = "Violin I"
    shortInstrumentName = "V I"
    \RemoveAllEmptyStaves
    \override VerticalAxisGroup.remove-layer = 1
  } \violI
  \new Staff \with {
    instrumentName = "Violin II"
    shortInstrumentName = "V II"
    \RemoveAllEmptyStaves
    \override VerticalAxisGroup.remove-layer = 1
  } \violII
>>

\RemoveAllEmptyStaves can also be used to create ossia sections for a staff. For details, see Ossia staves.

Known issues and warnings

Removing Staff_symbol_engraver also hides bar lines. If bar line visibility is forced, formatting errors may occur. In this case, use the following overrides instead of removing the engraver:

\omit StaffSymbol
\override NoteHead.no-ledgers = ##t

For the Known issues and warnings associated with \RemoveEmptyStaves see Changing context default settings.

1.6.3 Writing parts

This section explains how to prepare parts for orchestral or ensemble music, which often requires to insert instrument names into the score. Methods to quote other voices and to format cue notes are also described, as well as a way to contract multiple consecutive empty measures in individual parts.

Aditionally, a method for printing divisi staves, sometimes used in individual or desk parts, can be found in Hiding staves.

Instrument names

Instrument names can be printed on the left side of staves in the Staff, PianoStaff, StaffGroup, GrandStaff and ChoirStaff contexts. The value of instrumentName is used for the first staff, and the value of shortInstrumentName is used for all succeeding staves.

\new Staff \with { instrumentName = "Violin " shortInstrumentName = "Vln. " } \relative { c'4.. g'16 c4.. g'16 \break | c1 | }

\markup can be used to create more complex instrument names:

\new Staff \with { instrumentName = \markup { \column { "Clarinetti" \line { "in B" \smaller \flat } } } } \relative { c''4 c,16 d e f g2 }

When two or more staff contexts are grouped together, the instrument names and short instrument names are centered by default. To center multi-line instrument names, \center-column must be used:

<< \new Staff \with { instrumentName = "Flute" } \relative { f''2 g4 f } \new Staff \with { instrumentName = \markup { \center-column { "Clarinet" \line { "in B" \smaller \flat } } } } \relative { c''4 b c2 } >>

However, if the instrument names are longer, the instrument names in a staff group may not be centered unless the indent and short-indent settings are increased. For details about these settings, see \paper variables for shifts and indents.

<< \new Staff \with { instrumentName = "Alto Flute in G" shortInstrumentName = "Flt." } \relative { f''2 g4 f \break g4 f g2 } \new Staff \with { instrumentName = "Clarinet" shortInstrumentName = "Clar." } \relative { c''4 b c2 \break c2 b4 c } >> \layout { indent = 3.0\cm short-indent = 1.5\cm }

To add instrument names to other contexts (such as ChordNames or FiguredBass), Instrument_name_engraver must be added to that context. For details, see Modifying context plug-ins.

The shortInstrumentName may be changed in the middle of a piece, along with other settings as needed for the new instrument. However, only the first instance of instrumentName will be printed and subsequent changes will be ignored:

prepPiccolo = <>^\markup \italic { muta in Piccolo } prepFlute = <>^\markup \italic { muta in Flauto } setPiccolo = { <>^\markup \bold { Piccolo } \transposition c'' } setFlute = { <>^\markup \bold { Flute } \transposition c' } \new Staff \with { instrumentName = "Flute" shortInstrumentName = "Flt." } \relative { g'1 g g g \break g1 g \prepPiccolo R R \break \set Staff.instrumentName = "Piccolo" \set Staff.shortInstrumentName = "Picc." \setPiccolo g1 g g g \break g1 g \prepFlute R R \break \set Staff.instrumentName = "Flute" \set Staff.shortInstrumentName = "Flt." \setFlute g1 g g g }

Quoting other voices

It is very common for one voice to use the same notes as those from another voice. For example, first and second violins playing the same phrase during a particular passage of the music. This is done by letting one voice quote the other, without having to re-enter the music all over again for the second voice.

The \addQuote command, used in the top level scope, defines a stream of music from which fragments can be quoted.

The \quoteDuring command is used to indicate the point where the quotation begins. It is followed by two arguments: the name of the quoted voice, as defined with \addQuote, and a music expression for the duration of the quote.

fluteNotes = \relative { a'4 gis g gis | b4^"quoted" r8 ais\p a4( f) } oboeNotes = \relative { c''4 cis c b \quoteDuring "flute" { s1 } } \addQuote "flute" { \fluteNotes } \score { << \new Staff \with { instrumentName = "Flute" } \fluteNotes \new Staff \with { instrumentName = "Oboe" } \oboeNotes >> }

If the music expression used in \quoteDuring contains notes instead of spacer or multimeasure rests then the quote will appear as polyphony and may produce unexpected results.

fluteNotes = \relative { a'4 gis g gis | b4^"quoted" r8 ais\p a4( f) } oboeNotes = \relative { c''4 cis c b \quoteDuring "flute" { e4 r8 ais b4 a } } \addQuote "flute" { \fluteNotes } \score { << \new Staff \with { instrumentName = "Flute" } \fluteNotes \new Staff \with { instrumentName = "Oboe" } \oboeNotes >> }

If an \unfoldRepeats command in a music expression is required to be printed when using \quoteDuring, then it too must also contain its own \unfoldRepeats command;

fluteNotes = \relative { \repeat volta 2 { a'4 gis g gis } } oboeNotesDW = \relative { \repeat volta 2 \quoteDuring "incorrect" { s1 } } oboeNotesW = \relative { \repeat volta 2 \quoteDuring "correct" { s1 } } \addQuote "incorrect" { \fluteNotes } \addQuote "correct" { \unfoldRepeats \fluteNotes } \score { \unfoldRepeats << \new Staff \with { instrumentName = "Flute" } \fluteNotes \new Staff \with { instrumentName = "Oboe (incorrect)" } \oboeNotesDW \new Staff \with { instrumentName = "Oboe (correct)" } \oboeNotesW >> }

The \quoteDuring command uses the \transposition settings of both quoted and quoting parts to produce notes for the quoting part that have the same sounding pitch as those in the quoted part.

By default quoted music will include all articulations, dynamics, markups, etc., in the quoted expression. It is possible to choose which of these objects from the quoted music are displayed by using the quotedEventTypes context property.

Known issues and warnings

Only the contents of the first Voice occurring in an \addQuote command will be considered for quotation, so if the music expression contains \new or \context Voice statements, their contents will not be quoted. Quoting grace notes is unsupported and may cause LilyPond to crash whereas quoting nested triplets may result in poor notation.

Formatting cue notes

The simplest way to format cue notes is to explicitly create a CueVoice context within the part.

\relative {
  R1
  <<
    { e'2\rest r4. e8 }
    \new CueVoice {
      \stemUp d'8^"flute" c d e fis2
    }
  >>
  d,4 r a r
}

The \cueClef command can also be used with an explict CueVoice context if a change of clef is required and will print an appropriately sized clef for the cue notes. The \cueClefUnset command can then be used to switch back to the original clef, again with an appropriately sized clef.

\relative {
  \clef "bass"
  R1
  <<
    { e'2\rest r4. \cueClefUnset e,8 }
    \new CueVoice {
      \cueClef "treble" \stemUp d''8^"flute" c d e fis2
    }
  >>
  d,,4 r a r
}

The \cueClef and \cueClefUnset command can also be used without a CueVoice if required.

\relative {
  \clef "bass"
  R1
  \cueClef "treble"
  d''8^"flute" c d e fis2
  \cueClefUnset
  d,,4 r a r
}

For more complex cue note placement, e.g including transposition, or inserting cue notes from multiple music sources the \cueDuring or \cueDuringWithClef commands can be used. These are more specialized form of \quoteDuring, see Quoting other voices in the previous section.

The syntax is:

\cueDuring quotename #direction music

and

\cueDuringWithClef quotename #direction #clef music

The music from the corresponding measures of the quote name is added as a CueVoice context and occurs simultaneously with the music, which then creates a polyphonic situation. The direction takes the argument UP or DOWN, and corresponds to the first and second voices respectively, determining how the cue notes are printed in relation to the other voice.

fluteNotes = \relative { r2. c''4 | d8 c d e fis2 | g2 d | } oboeNotes = \relative c'' { R1 <>^\markup \tiny { flute } \cueDuring "flute" #UP { R1 } g2 c, } \addQuote "flute" { \fluteNotes } \new Staff { \oboeNotes }

It is possible to adjust which aspects of the music are quoted with \cueDuring by setting the quotedCueEventTypes property. Its default value is '(note-event rest-event tie-event beam-event tuplet-span-event), which means that only notes, rests, ties, beams and tuplets are quoted, but not articulations, dynamic marks, markup, etc.

oboeNotes = \relative { r2 r8 d''16(\f f e g f a) g8 g16 g g2. } \addQuote "oboe" { \oboeNotes } \new Voice \relative c'' { \set Score.quotedCueEventTypes = #'(note-event rest-event tie-event beam-event tuplet-span-event dynamic-event slur-event) \cueDuring "oboe" #UP { R1 } g2 c, }

Markup can be used to show the name of the quoted instrument. If the cue notes require a change in clef, this can be done manually but the original clef should also be restored manually at the end of the cue notes.

fluteNotes = \relative { r2. c''4 d8 c d e fis2 g2 d2 } bassoonNotes = \relative c { \clef bass R1 \clef treble <>^\markup \tiny { flute } \cueDuring "flute" #UP { R1 } \clef bass g4. b8 d2 } \addQuote "flute" { \fluteNotes } \new Staff { \bassoonNotes }

Alternatively, the \cueDuringWithClef function can be used instead. This command takes an extra argument to specify the change of clef that needs to be printed for the cue notes but will automatically print the original clef once the cue notes have finished.

fluteNotes = \relative { r2. c''4 d8 c d e fis2 g2 d2 } bassoonNotes = \relative c { \clef bass R1 <>^\markup { \tiny "flute" } \cueDuringWithClef "flute" #UP "treble" { R1 } g4. b8 d2 } \addQuote "flute" { \fluteNotes } \new Staff { \bassoonNotes }

Like \quoteDuring, \cueDuring takes instrument transpositions into account. Cue notes are produced at the pitches that would be written for the instrument receiving the cue to produce the sounding pitches of the source instrument.

To transpose cue notes differently, use \transposedCueDuring. This command takes an extra argument to specify (in absolute mode) the printed pitch that you want to represent the sound of a concert middle C. This is useful for taking cues from an instrument in a completely different register.

piccoloNotes = \relative { \clef "treble^8" R1 c'''8 c c e g2 c4 g g2 } bassClarinetNotes = \relative c' { \key d \major \transposition bes, d4 r a r \transposedCueDuring "piccolo" #UP d { R1 } d4 r a r } \addQuote "piccolo" { \piccoloNotes } << \new Staff \piccoloNotes \new Staff \bassClarinetNotes >>

The \killCues command removes cue notes from a music expression, so the same music expression can be used to produce the instrument part with cues and the score. The \killCues command removes only the notes and events that were quoted by \cueDuring. Other markup associated with cues, such as clef changes and a label identifying the source instrument, can be tagged for selective inclusion in the score; see Using tags.

fluteNotes = \relative { r2. c''4 d8 c d e fis2 g2 d2 } bassoonNotes = \relative c { \clef bass R1 \tag #'part { \clef treble <>^\markup \tiny { flute } } \cueDuring "flute" #UP { R1 } \tag #'part \clef bass g4. b8 d2 } \addQuote "flute" { \fluteNotes } \new Staff { \bassoonNotes } \new StaffGroup << \new Staff { \fluteNotes } \new Staff { \removeWithTag #'part { \killCues { \bassoonNotes } } } >>

Known issues and warnings

Collisions can occur with rests, when using \cueDuring, between Voice and CueVoice contexts. When using \cueDuringWithClef or \transposedCueDuring the extra argument required for each case must come after the quote and the direction.

Compressing empty measures

By default, all measures are printed even if they are empty – which can happen if a rhythmic event (such as notes, rests or invisible rests) is so long as to span several measures. This behaviour can be changed by contracting all empty measures into a single one, as illustrated here (the second part of this example, with expanded measures, actually reverts back to the default behavior):

\override Score.BarNumber.break-visibility = ##(#f #t #t) \time 2/4 \compressEmptyMeasures c'1 d'1. e'\breve \bar "||" \expandEmptyMeasures c'1 d'1. e'\breve

Although that notation is syntactically correct, it may be confusing from a musical point of view, as illustrated in the previous example; hence the need for measure numbers to be explicitly printed, using the syntax described in Using break-visibility.

Where such a notation may become more useful is when applied to Full measure rests. A multi-measure rest will then be shown as a single measure containing a multi-measure rest symbol, with the number of measures of rest printed above the measure:

% Default behavior \time 3/4 r2. | R2.*2 | \time 2/4 R2 | \time 4/4 % Rest measures contracted to single measure \compressEmptyMeasures r1 | R1*17 | R1*4 | \expandEmptyMeasures % Rest measures expanded again \time 3/4 R2.*2 |

Unlike \compressEmptyMeasures, the music function \compressMMRests will only apply to rests, leaving any other events uncompressed. As a function rather than a property setting, its syntax differs slightly in that it must be followed by a music expression:

\compressMMRests { % Rests are compressed… R1*7 % … but notes can still span multiple measures. g'1 a'1*2 d'1 R1*2 }

All of the commands described in this section actually rely on the skipBars internal property, which is set in the Score context as explained in The \set command.

Predefined commands

\compressEmptyMeasures, \expandEmptyMeasures, \compressMMRests.

Selected Snippets

Numbering single measure rests

Multi measure rests show their length by a number except for single measures. This can be changed by setting restNumberThreshold.

{ \compressEmptyMeasures R1 R1*10 R1*11 \bar "||" \set restNumberThreshold = 0 R1 R1*10 R1*11 \bar "||" \set restNumberThreshold = 10 R1 R1*10 R1*11 }

Changing form of multi-measure rests

If there are ten or fewer measures of rests, a series of longa and breve rests (called in German “Kirchenpausen” - church rests) is printed within the staff; otherwise a simple line is shown. This default number of ten may be changed by overriding the expand-limit property.

\relative c'' { \compressMMRests { R1*2 | R1*5 | R1*9 \override MultiMeasureRest.expand-limit = #3 R1*2 | R1*5 | R1*9 } }
