Node:RhythmicStaff, Next:Score, Previous:PianoStaff, Up:LilyPond interpretation contexts

RhythmicStaff

A context like Staff but for printing rhythms. Pitches are ignored; the notes are printed on one line. It can contain Voice contexts.

This context creates the following grobs: BarLine, SeparatingGroupSpanner, SeparationItem, StaffSymbol, TimeSignature, VerticalAxisGroup and VoltaBracket.

Context RhythmicStaff can contain Voice

This context is built from the following engravers:

Engraver_group_engraver

A group of engravers taken together

Engraver_group_engraver is part of contexts: Lyrics, ChoirStaff, LyricsVoice, PianoStaff, GrandStaff, Thread, RhythmicStaff, Voice, Staff, ChordNames, StaffContainer, InnerStaffGroup, InnerChoirStaff, NoteNames and StaffGroup

Staff_symbol_engraver

create the constellation of five (default) staff lines.

This engraver creates the following grobs: StaffSymbol.

Staff_symbol_engraver is part of contexts: RhythmicStaff and Staff

Time_signature_engraver

Create a TimeSignature whenever timeSignatureFraction changes

This engraver creates the following grobs: TimeSignature.

Time_signature_engraver is part of contexts: RhythmicStaff and Staff

Bar_engraver

Create barlines. This engraver is controlled through the whichBar property. If it has no bar line to create, it will forbid a linebreak at this point

Properties

whichBar (string):

This property is read to determine what type of barline to create.

Example:

\property Staff.whichBar = "|:"

This will create a start-repeat bar in this staff only.

If not set explicitly (by property or bar), this is set according to values of defaultBarType, barAlways, barNonAuto and measurePosition.

Valid values are described in (lilypond-internals)bar-line-interface.

.

staffsFound (list):

list of all staff-symbols found.

Bar_engraver is part of contexts: RhythmicStaff and Staff

Volta_engraver

Make volta brackets

Properties

repeatCommands (list):

This property is read to find any command of the form (volta . X), where X is a string or #f

voltaSpannerDuration (moment):

maximum duration of the volta bracket.

Set to a duration to control the size of the brackets printed by \alternative. It specifies the number of whole notes duration to use for the brackets. This can be used to shrink the length of brackets in the situation where one alternative is very large. It may have odd effects if the specified duration is longer than the music given in an \alternative. .

Volta_engraver is part of contexts: RhythmicStaff and Staff

Separating_line_group_engraver

Generates objects for computing spacing parameters.

This engraver creates the following grobs: SeparatingGroupSpanner and SeparationItem.

Separating_line_group_engraver is part of contexts: LyricsVoice, RhythmicStaff, Staff, ChordNames and NoteNames

Pitch_squash_engraver

Treat all pitches as middle C. Note that the notes move, but the locations of accidentals stay the same. Set the position field of all note heads to zero. This useful for making a single line staff that demonstrates the rhythm of a melody.

Properties

squashedPosition (integer):

Vertical position of squashing for Pitch_squash_engraver.

Pitch_squash_engraver is part of contexts: RhythmicStaff

Output_property_engraver

Interpret Music of Output_property type, and apply a function to any Graphic objects that satisfies the predicate.

Output_property_engraver is part of contexts: Grace, Thread, RhythmicStaff, Voice, Staff, Score, ChordNames, InnerStaffGroup and StaffGroup

Property_engraver

This is a engraver that converts property settings into back-end grob-property settings. Example: Voice.stemLength will set #'length in all Stem objects.

Due to CPU and memory requirements, the use of this engraver is deprecated.

Properties

Generic_property_list (list):

description of the conversion.

Defines names and types for generic properties. These are properties than can be plugged into the backend directly. See the init file generic-property.scm for details. For internal use only, deprecated.

Property_engraver is part of contexts: Lyrics, PianoStaff, GrandStaff, Grace, Thread, RhythmicStaff, Voice, Staff and ChordNames

Axis_group_engraver

Group all objects created in this context in a VerticalAxisGroup spanner.

Properties

VerticalExtent (pair of numbers):

hard coded vertical extent. The format is a pair of dimensions, for example, this sets the sizes of a staff to 10 (5+5) staffspaces high.

property Staff.VerticalExtent = #(-5.0 . 5.0)

VerticalExtent, MinimumVerticalExtent and ExtraVerticalExtent are predefined in all relevant contexts to #f, so they will not inherit values.

Note that these VerticalExtents can only operate on vertical groups, and therefore only work in contexts which contain an Axis_group_engraver.

MinimumVerticalExtent (pair of numbers):

minimum vertical extent, same format as VerticalExtent

ExtraVerticalExtent (pair of numbers):

extra vertical extent, same format as MinimumVerticalExtent

Axis_group_engraver is part of contexts: Lyrics, LyricsVoice, RhythmicStaff, Staff, ChordNames, StaffContainer and NoteNames
