## Adding ambitus per voice

Ambitus can be added per voice. In this case, the ambitus must be moved manually to prevent collisions.

    \new Staff <<
      \new Voice \with {
        \consists "Ambitus_engraver"
      } \relative c'' {
        \override Ambitus #'X-offset = #2.0
        \voiceOne
        c4 a d e
        f1
      }
      \new Voice \with {
        \consists "Ambitus_engraver"
      } \relative c' {
        \voiceTwo
        es4 f g as
        b1
      }
    >>

## Adding an extra staff at a line break

When adding a new staff at a line break, some extra space is unfortunately added at the end of the line before the break (to fit in a key signature change, which will never be printed anyway). The workaround is to add a setting of `Staff.explicitKeySignatureVisibility` as is shown in the example.

    \score {
      \new StaffGroup \relative c'' {
        \new Staff
        \key f \major
        c1 c^"Unwanted extra space" \break
        << { c1 | c }
           \new Staff {
             \key f \major
             \once \override Staff.TimeSignature #'stencil = ##f
             c1 | c
           }
        >>
        c1 | c^"Fixed here" \break
        << { c1 | c }
           \new Staff {
             \once \set Staff.explicitKeySignatureVisibility = #end-of-line-invisible
             \key f \major
             \once \override Staff.TimeSignature #'stencil = ##f
             c1 | c
           }
        >>
      }
    }

## Adding an extra staff

An extra staff can be added (possibly temporarily) after the start of a piece.

    \score {
      <<
        \new Staff \relative c'' {
          c1 | c | c | c | c
        }
        \new StaffGroup \relative c'' {
          \new Staff {
            c1 | c
            <<
              {
                c1 | d
              }
              \new Staff {
                \once \override Staff.TimeSignature #'stencil = ##f
                c1 | b
              }
            >>
            c1
          }
        }
      >>
    }

## Adding indicators to staves which get split after a break

This snippet defines the `\splitStaffBarLine` command, which adds arrows in north-east and south-east directions at a bar line, to denote that several voices sharing a staff will each continue on a staff of their own in the next system.

## Adding orchestral cues to a vocal score

This shows one approach to simplify adding many orchestral cues to the piano reduction in a vocal score. The music function `\cueWhile` takes four arguments: the music from which the cue is to be taken, as defined by `\addQuote`, the name to be inserted before the cue notes, then either `#UP` or `#DOWN` to specify either `\voiceOne` with the name above the staff or `\voiceTwo` with the name below the staff, and finally the piano music in parallel with which the cue notes are to appear. The name of the cued instrument is positioned to the left of the cued notes. Many passages can be cued, but they cannot overlap each other in time.

    cueWhile =
    #(define-music-function
       (parser location instrument name dir music)
       (string? string? ly:dir? ly:music?)
       #{
         \cueDuring $instrument #$dir {
           \once \override TextScript #'self-alignment-X = #RIGHT
           \once \override TextScript #'direction = $dir
           s1*0-\markup { \tiny $name }
           $music
         }
       #})

    flute = \relative c'' {
      \transposition c'
      s4 s4 e g
    }
    \addQuote "flute" { \flute }

    clarinet = \relative c' {
      \transposition bes
      fis4 d d c
    }
    \addQuote "clarinet" { \clarinet }

    singer = \relative c'' { c4. g8 g4 bes4 }
    words = \lyricmode { here's the lyr -- ics }

    pianoRH = \relative c'' {
      \transposition c'
      \cueWhile "clarinet" "Clar." #DOWN { c4. g8 }
      \cueWhile "flute" "Flute" #UP { g4 bes4 }
    }
    pianoLH = \relative c { c4 <c' e> e, <g c> }

    \score {
      <<
        \new Staff {
          \new Voice = "singer" {
            \singer
          }
        }
        \new Lyrics {
          \lyricsto "singer"
          \words
        }
        \new PianoStaff <<
          \new Staff {
            \new Voice {
              \pianoRH
            }
          }
          \new Staff {
            \clef "bass"
            \pianoLH
          }
        >>
      >>
    }

## Changing the number of lines in a staff

The number of lines in a staff may changed by overriding the `StaffSymbol` property `line-count`.

    upper = \relative c'' {
      c4 d e f
    }

    lower = \relative c {
      \clef bass
      c4 b a g
    }

    \score {
      \context PianoStaff <<
        \new Staff {
          \upper
        }
        \new Staff {
          \override Staff.StaffSymbol #'line-count = #4
          \lower
        }
      >>
    }

## Changing the staff size

Though the simplest way to resize staves is to use `#(set-global-staff-size xx)`, an individual staff’s size can be changed by scaling the properties `'staff-space` and `fontSize`.

    <<
      \new Staff {
        \relative c'' {
          \dynamicDown
          c8\ff c c c c c c c
        }
      }
      \new Staff \with {
        fontSize = #-3
        \override StaffSymbol #'staff-space = #(magstep -3)
      } {
        \clef bass
        c8 c c c c\f c c c
      }
    >>

## Creating blank staves

To create blank staves, generate empty measures then remove the `Bar_number_engraver` from the `Score` context, and the `Time_signature_engraver`, `Clef_engraver` and `Bar_engraver` from the `Staff` context.

    #(set-global-staff-size 20)

    \score {
      {
        \repeat unfold 12 { s1 \break }
      }
      \layout {
        indent = 0\in
        \context {
          \Staff
          \remove "Time_signature_engraver"
          \remove "Clef_engraver"
          \remove "Bar_engraver"
        }
        \context {
          \Score
          \remove "Bar_number_engraver"
        }
      }
    }

    \paper {
      #(set-paper-size "letter")
      ragged-last-bottom = ##f
      line-width = 7.5\in
      left-margin = 0.5\in
      bottom-margin = 0.25\in
      top-margin = 0.25\in
    }

## Display bracket with only one staff in a system

If there is only one staff in one of the staff types `ChoirStaff` or `StaffGroup`, the bracket and the starting bar line will not be displayed as standard behavior. This can be changed by overriding the relevant properties.

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.

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

## Forcing measure width to adapt to MetronomeMark’s width

By default, metronome marks do not influence horizontal spacing. This has one downside: when using compressed rests, some metronome marks may be too close and therefore are printed vertically stacked, as demonstrated in the first part of this example. This can be solved through a simple override, as shown in the second half of the example.

    example = {
      \tempo "Allegro"
      R1*6
      \tempo "Rall."
      R1*2
      \tempo "A tempo"
      R1*8
    }

    {
      \compressFullBarRests

      \example

      R1
      R1

      \override Score.MetronomeMark #'extra-spacing-width = #'(0 . 0)
      \example
    }

## How to print two rehearsal marks above and below the same barline (method 1)

This method prints two ’rehearsal marks’, one on top of the other. It shifts the lower rehearsal mark below the staff and then adds padding above it in order to place the upper rehearsal mark above the staff.

By adjusting the extra-offset and baseline-skip values you can increase or decrease the overall space between the rehearsal mark and the staff.

Because nearly every type of glyph or string can be made to behave like a rehearsal mark it is possible to centre those above and below a bar line.

Adding the appropriate ’break visibility’ as shown in snippet 1 will allow you to position two marks at the end of a line as well.

Note: Method 1 is less complex than Method 2 but does not really allow for fine tuning of placement of one of the rehearsal marks without affecting the other. It may also give some problems with vertical spacing, since using `extra-offset` does not change the bounding box of the mark from its original value.

    \relative c'{
        c d e f |
        \once \override Score.RehearsalMark #'extra-offset = #'(0 . -8.5)
        \once \override Score.RehearsalMark #'baseline-skip = #9
        \mark \markup \center-column { \circle 1 \box A }
        g f e d |
        \once \override Score.RehearsalMark #'extra-offset = #'(0 . -8.5)
        \once \override Score.RehearsalMark #'baseline-skip = #9
        \mark \markup \center-column { \flat { \bold \small \italic Fine. } }
        g f e d |
        \once \override Score.RehearsalMark #'extra-offset = #'(0 . -8.5)
        \once \override Score.RehearsalMark #'baseline-skip = #9
        \override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
        \mark \markup \center-column { \musicglyph #"scripts.ufermata" \box z }
    }

## How to print two rehearsal marks above and below the same barline (method 2)

This method prints two ’rehearsal marks’ - one above the stave and one below, by creating two voices, adding the Rehearsal Mark engraver to each voice - without this no rehearsal mark is printed - and then placing each rehearsal mark UP and DOWN in each voice respectively.

This method (as opposed to method 1) is more complex, but allows for more flexibility, should it be needed to tweak each rehearsal mark independently of the other.

    \score {
      \relative c'
      <<
        \new Staff {
          <<
            \new Voice \with {
              \consists Mark_engraver
              \consists "Staff_collecting_engraver"
            }
            { c4 d e f
              \mark \markup { \box A }
              c4 d e f
            }
            \new Voice \with {
              \consists Mark_engraver
              \consists "Staff_collecting_engraver"
              \override RehearsalMark #'direction = #DOWN
            }
            { s4 s s s
              \mark \markup { \circle 1 }
              s4 s s s
            }
          >>
        }
      >>
      \layout {
        \context {
          \Score
          \remove "Mark_engraver"
          \remove "Staff_collecting_engraver"
        }
      }
    }

## Inserting score fragments above a staff as markups

The `\markup` command is quite versatile. In this snippet, it contains a `\score` block instead of texts or marks.

    tuning = \markup {
      \score {
        \new Staff \with { \remove "Time_signature_engraver" }
        {
          \clef bass
          <c, g, d g>1
        }
        \layout { ragged-right = ##t }
      }
    }

    \header {
      title = "Solo Cello Suites"
      subtitle = "Suite IV"
      subsubtitle = \markup { Originalstimmung: \general-align #Y #CENTER \tuning }
    }

    \layout { ragged-right = ##f }

    \relative c'' {
      \time 4/8
      \times 2/3 { c8 d e } \times 2/3 { c d e }
      \times 2/3 { c8 d e } \times 2/3 { c d e }
      g8 a g a
      g8 a g a
    }

## Letter tablature formatting

Tablature can be formatted using letters instead of numbers.

    music = \relative c {
      c4 d e f
      g4 a b c
      d4 e f g
    }

    <<
      \new Staff {
        \clef "G_8"
        \music
      }
      \new TabStaff \with {
        tablatureFormat = #fret-letter-tablature-format
      }
      {
        \music
      }
    >>

## Making some staff lines thicker than the others

For pedagogical 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'
    }

## Measure counter

This snippet provides a workaround for emitting measure counters using transparent percent repeats.

    <<
      \context Voice = "foo" {
        \clef bass
        c4 r g r
        c4 r g r
        c4 r g r
        c4 r g r
      }
      \context Voice = "foo" {
        \set countPercentRepeats = ##t
        \override PercentRepeat #'transparent = ##t
        \override PercentRepeatCounter #'staff-padding = #1
        \repeat percent 4 { s1 }
      }
    >>

## 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 by setting the `transparent` property.

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

## Modern TAB text clef

Use a markup text to replace the (TAB) clef glyph with a modern font.

    \markup {
      This snippet is deprecated as of version 2.13.4 and will be removed
      in version 2.14.
    }

## 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'' <<
      \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 }
    >>

## Non-traditional key signatures

The commonly used `\key` command sets the `keySignature` property, in the `Staff` context.

To create non-standard key signatures, set this property directly. The format of this command is a list:

`\set Staff.keySignature = #`(((octave . step) . alter) ((octave . step) . alter) ...)` where, for each element in the list, `octave` specifies the octave (0 being the octave from middle C to the B above), `step` specifies the note within the octave (0 means C and 6 means B), and `alter` is `,SHARP ,FLAT ,DOUBLE-SHARP` etc. (Note the leading comma.)

Alternatively, for each item in the list, using the more concise format `(step . alter)` specifies that the same alteration should hold in all octaves.

Here is an example of a possible key signature for generating a whole-tone scale:

    \relative c' {
      \set Staff.keySignature = #`(((0 . 6) . ,FLAT)
                                   ((0 . 5) . ,FLAT)
                                   ((0 . 3) . ,SHARP))
      c4 d e fis
      aes4 bes c2
    }

## Orchestra choir and piano template

This template demonstrates the use of nested `StaffGroup` and `GrandStaff` contexts to sub-group instruments of the same type together, and a way to use `\transpose` so that variables hold music for transposing instruments at concert pitch.

    #(set-global-staff-size 17)
    \paper {
      indent = 3.0\cm  % space for instrumentName
      short-indent = 1.5\cm  % space for shortInstrumentName

## Putting lyrics inside the staff

Lyrics can be moved vertically to place them inside the staff. The lyrics are moved with `\override LyricText #'extra-offset = #'(0 . dy)` and there are similar commands to move the extenders and hyphens. The offset needed is established with trial and error.

    <<
      \new Staff <<
        \new Voice = "voc" \relative c' { \stemDown a bes c8 b c4 }
    >>
      \new Lyrics \with {
        \override LyricText #'extra-offset = #'(0 . 8.6)
        \override LyricExtender #'extra-offset = #'(0 . 8.6)
        \override LyricHyphen #'extra-offset = #'(0 . 8.6)
      } \lyricsto "voc" { La la -- la __ _ la }
    >>

## Quoting another voice with transposition

Quotations take into account the transposition of both source and target. In this example, all instruments play sounding middle C; the target is an instrument in F. The target part may be transposed using `\transpose`. In this case, all the pitches (including the quoted ones) are transposed.

    \addQuote clarinet {
      \transposition bes
      \repeat unfold 8 { d'16 d' d'8 }
    }

    \addQuote sax {
      \transposition es'
      \repeat unfold 16 { a8 }
    }

    quoteTest = {
      % french horn
      \transposition f
      g'4
      << \quoteDuring #"clarinet" { \skip 4 } s4^"clar." >>
      << \quoteDuring #"sax" { \skip 4 } s4^"sax." >>
      g'4
    }

    {
      \set Staff.instrumentName =
        \markup {
          \center-column { Horn \line { in F } }
        }
      \quoteTest
      \transpose c' d' << \quoteTest s4_"up a tone" >>
    }

## Quoting another voice

The `quotedEventTypes` property determines the music event types which should be quoted. The default value is `(note-event rest-event tie-event beam-event tuplet-span-event)`, which means that only the notes, rests, ties, beams and tuplets of the quoted voice will appear in the `\quoteDuring` expression. In the following example, a 16th rest is not quoted since `rest-event` is not in `quotedEventTypes`.

For a list of event types, consult the “Music classes” section of the Internals Reference.

    quoteMe = \relative c' {
      fis4 r16 a8.-> b4\ff c
    }
    \addQuote quoteMe \quoteMe

    original = \relative c'' {
      c8 d s2

        \set Staff.instrumentName = #"orig"

      }
      \new Staff \relative c'' <<
        \set Staff.instrumentName = #"orig+quote"
        \set Staff.quotedEventTypes =
          #'(note-event articulation-event)
        \original
        \new Voice {
          s4
          \set fontSize = #-4
          \override Stem #'length-fraction = #(magstep -4)
          \quoteDuring #"quoteMe" { \skip 2. }
        }

## Removing the first empty line

The first empty staff can also be removed from the score by setting the `VerticalAxisGroup` property `remove-first`. This can be done globally inside the `\layout` block, or locally inside the specific staff that should be removed. In the latter case, you have to specify the context (`Staff` applies only to the current staff) in front of the property.

The lower staff of the second staff group is not removed, because the setting applies only to the specific staff inside of which it is written.

    \layout {
      \context {
        \Staff \RemoveEmptyStaves
        % To use the setting globally, uncomment the following line:
        % \override VerticalAxisGroup #'remove-first = ##t
      }
    }
    \new StaffGroup <<
      \new Staff \relative c' {
        e4 f g a \break
        c1
      }
      \new Staff {
        % To use the setting globally, comment this line,
        % uncomment the line in the \layout block above
        \override Staff.VerticalAxisGroup #'remove-first = ##t
        R1 \break
        R
      }
    >>
    \new StaffGroup <<
      \new Staff \relative c' {
        e4 f g a \break
        c1
      }
      \new Staff {
        R1 \break
        R
      }
    >>

## Setting system separators

System separators can be inserted between systems. Any markup can be used, but `\slashSeparator` has been provided as a sensible default.

    \paper {
      system-separator-markup = \slashSeparator
    }

    notes = \relative c' {
      c1 | c \break
      c1 | c \break
      c1 | c
    }

    \book {
      \score {
        \new GrandStaff <<
          \new Staff \notes
          \new Staff \notes
        >>
      }
    }

## Tick bar lines

’Tick’ bar lines are often used in music where the bar line is used only for coordination and is not meant to imply any rhythmic stress.

    \relative c' {
      \set Score.defaultBarType = #"'"
      c4 d e f
      g4 f e d
      c4 d e f
      g4 f e d
      \bar "|."
    }

## Time signature in parentheses

The time signature can be enclosed within parentheses.

    \relative c'' {
      \override Staff.TimeSignature #'stencil = #(lambda (grob)
        (bracketify-stencil (ly:time-signature::print grob) Y 0.1 0.2 0.1))
      \time 2/4
      a4 b8 c
    }

## Tweaking clef properties

The command `\clef "treble_8"` is equivalent to setting `clefGlyph`, `clefPosition` (which controls the vertical position of the clef), `middleCPosition` and `clefOctavation`. A clef is printed when any of the properties except `middleCPosition` are changed.

Note that changing the glyph, the position of the clef, or the octavation does not in itself change the position of subsequent notes on the staff: the position of middle C must also be specified to do this. The positional parameters are relative to the staff center line, positive numbers displacing upwards, counting one for each line and space. The `clefOctavation` value would normally be set to 7, -7, 15 or -15, but other values are valid.

When a clef change takes place at a line break the new clef symbol is printed at both the end of the previous line and the beginning of the new line by default. If the warning clef at the end of the previous line is not required it can be suppressed by setting the `Staff` property `explicitClefVisibility` to the value `end-of-line-invisible`. The default behavior can be recovered with `\unset Staff.explicitClefVisibility`.

The following examples show the possibilities when setting these properties manually. On the first line, the manual changes preserve the standard relative positioning of clefs and notes, whereas on the second line, they do not.

    \layout { ragged-right = ##t }

    {
      % The default treble clef
      c'1
      % The standard bass clef
      \set Staff.clefGlyph = #"clefs.F"
      \set Staff.clefPosition = #2
      \set Staff.middleCPosition = #6
      c'1
      % The baritone clef
      \set Staff.clefGlyph = #"clefs.C"
      \set Staff.clefPosition = #4
      \set Staff.middleCPosition = #4
      c'1
      % The standard choral tenor clef
      \set Staff.clefGlyph = #"clefs.G"
      \set Staff.clefPosition = #-2
      \set Staff.clefOctavation = #-7
      \set Staff.middleCPosition = #1
      c'1
      % A non-standard clef
      \set Staff.clefPosition = #0
      \set Staff.clefOctavation = #0
      \set Staff.middleCPosition = #-4
      c'1 \break

      % The following clef changes do not preserve
      % the normal relationship between notes and clefs:

      \set Staff.clefGlyph = #"clefs.F"
      \set Staff.clefPosition = #2
      c'1
      \set Staff.clefGlyph = #"clefs.G"
      c'1
      \set Staff.clefGlyph = #"clefs.C"
      c'1
      \set Staff.clefOctavation = #7
      c'1
      \set Staff.clefOctavation = #0
      \set Staff.clefPosition = #0
      c'1

      % Return to the normal clef:

      \set Staff.middleCPosition = #0
      c'1
    }

## 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 `ChoirStaffGroup` context.

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

## Volta below chords

By adding the `Volta_engraver` to the relevant staff, volte can be put under chords.

    \score {
      <<
        \chords {
          c1
          c1
        }
        \new Staff \with {
          \consists "Volta_engraver"
        }
        {
          \repeat volta 2 { c'1 }
          \alternative { c' }
        }
      >>
      \layout {
        \context {
          \Score
          \remove "Volta_engraver"
        }
      }
    }

## Volta multi staff

By adding the `Volta_engraver` to the relevant staff, volte can be put over staves other than the topmost one in a score.

    voltaMusic = \relative c'' {
      \repeat volta 2 {
        c1
      }
      \alternative {
        d1
        e1
      }
    }

    <<
      \new StaffGroup <<
        \new Staff \voltaMusic
        \new Staff \voltaMusic
      >>
      \new StaffGroup <<
        \new Staff \with { \consists "Volta_engraver" }
          \voltaMusic
        \new Staff \voltaMusic
      >>
    >>
