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 its staves are only removed together, never separately;
see Hiding staves.
The OneStaff
is a staff group that places separate contexts
in the same vertical alignment. This example shows three staves
sharing the same space. Here, the Time_signature_engraver
has been moved from the staves to the OneStaff
context to
prevent it from being repeated for each staff.
\layout { \context { \OneStaff \consists Time_signature_engraver } \context { \Staff \remove Time_signature_engraver } \context { \DrumStaff \remove Time_signature_engraver } } \new OneStaff { \new Staff { c'4 4 d'4 4 e'2 d' } \drums { hihat4 hh bassdrum bd } \new Staff { c'4 4 d'4 4 e'2 d' } }
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 } >> } \paper { tagline = ##f }
Mensurstriche layout (bar lines between the staves)
Mensurstriche, bar lines between but not through staves, can be
printed by setting measureBarType
to "-span|"
and using a
grouping context that allows span bars, such as StaffGroup
.
\layout { \context { \Staff measureBarType = "-span|" } } music = \fixed c'' { c1 d2 \section e2 f1 \fine } \new StaffGroup << \new Staff \music \new Staff \music >>
