2.1.19 Score
This is the top level notation context. No
other context can contain a 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 staves.
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 \score
or
\layout
block) is processed.
This context creates the following layout object(s):
BarNumber, BreakAlignGroup, BreakAlignment, GraceSpacing, LeftEdge, MetronomeMark, NonMusicalPaperColumn, PaperColumn, ParenthesesItem, RehearsalMark, SpacingSpanner, SystemStartBar, SystemStartBrace, SystemStartBracket, SystemStartSquare, VerticalAlignment, VoltaBracketSpanner and VoltaBracket.

This engraver creates the following layout object(s):
Break_align_engraver
Align grobs with corresponding
break-align-symbols
into groups, and order the groups according tobreakAlignOrder
. The left edge of the alignment gets a separate group, with a symbolleft-edge
.This engraver creates the following layout object(s):
Metronome_mark_engraver
Engrave metronome marking. This delegates the formatting work to the function in the
metronomeMarkFormatter
property. The mark is put over all staves. The staves are taken from thestavesFound
property, which is maintained by Staff_collecting_engraver.Properties (read)
stavesFound
(list of grobs)A list of all staff-symbols found.
metronomeMarkFormatter
(procedure)How to produce a metronome markup. Called with four arguments: text, duration, count and context.
tempoUnitDuration
(duration)Unit for specifying tempo.
tempoUnitCount
(number)Count for specifying tempo.
tempoText
(markup)Text for tempo marks.
tempoHideNote
(boolean)Hide the note=count in tempo marks.
This engraver creates the following layout object(s):
Volta_engraver
Make volta brackets.
Properties (read)
repeatCommands
(list)This property is a list of commands of the form
(list 'volta x)
, where x is a string or#f
.'end-repeat
is also accepted as a command.voltaSpannerDuration
(moment)This specifies the maximum duration to use for the brackets printed for
\alternative
. This can be used to shrink the length of brackets in the situation where one alternative is very large.stavesFound
(list of grobs)A list of all staff-symbols found.
This engraver creates the following layout object(s):
Mark_engraver
Create
RehearsalMark
objects. It puts them on top of all staves (which is taken from the propertystavesFound
). If moving this engraver to a different context, Staff_collecting_engraver must move along, otherwise all marks end up on the same Y location.Music types accepted:
Properties (read)
markFormatter
(procedure)A procedure taking as arguments the context and the rehearsal mark. It should return the formatted mark as a markup object.
rehearsalMark
(integer)The last rehearsal mark printed.
stavesFound

SystemStartBar
,SystemStartBrace
,SystemStartBracket
orSystemStartSquare
spanner).Properties (read)
systemStartDelimiter
(symbol)Which grob to make for the start of the system/staff? Set to
SystemStartBrace
,SystemStartBracket
orSystemStartBar
.systemStartDelimiterHierarchy
(pair)A nested list, indicating the nesting of a start delimiters.
currentCommandColumn
(layout object)Grob that is X-parent to all current breakable (clef, key signature, etc.) items.
