2.1.20 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, VoltaBracket and VoltaBracketSpanner.

Properties (write)
automaticBars(boolean)If set to false then bar lines will not be printed automatically; they must be explicitly created with a

This engraver creates the following layout object(s):
Metronome_mark_engraverEngrave metronome marking. This delegates the formatting work to the function in the

Properties (read)
currentCommandColumn(graphical (layout) object)Grob that is X-parent to all current breakable (clef, key signature, etc.) items.

This engraver creates the following layout object(s):
Output_property_engraverApply a procedure to any grob acknowledged.
Music types accepted:
Paper_column_engraverTake care of generating columns.
This engraver decides whether a column is breakable. The default is that a column is always breakable. However, every
Bar_engraverthat does not have a barline at a certain point will setforbidBreaksin the score context to stop line breaks. In practice, this means that you can make a break point by creating a bar line (assuming that there are no beams or notes that prevent a break point).Music types accepted:
Properties (read)
forbidBreak(boolean)If set to
##t, prevent a line break at this point.Properties (write)
currentCommandColumn(graphical (layout) object)Grob that is X-parent to all current breakable (clef, key signature, etc.) items.
currentMusicalColumn(graphical (layout) object)Grob that is X-parent to all non-breakable items (note heads, lyrics, etc.).
forbidBreak(boolean)If set to
##t, prevent a line break at this point.This engraver creates the following layout object(s):
Parenthesis_engraverParenthesize objects whose music cause has the
parenthesizeproperty.This engraver creates the following layout object(s):

repeatCommandsinto an appropriate setting forwhichBar.Properties (read)
doubleRepeatType(string)Set the default bar line for double repeats.
repeatCommands(list)This property is a list of commands of the form
