Context TabStaff can contain
TabVoice
This context is built from the following engravers:
- Engraver_group_engraver
- A group of engravers taken together
- Forbid_line_break_engraver
- Forbid line breaks when note heads are still playing at some point.
Properties (read)
busyGrobs (list)
-
a queue of (END-MOMENT . GROB) conses. This is for internal (C++) use only.
Use at your own risk. This property contains the grobs for which END-MOMENT >= NOW.
- Grob_pq_engraver
- Administrate when certain grobs (eg. note heads) stop playing; this engraver is a sort-of a failure, since it doesn't handle all sorts of borderline cases very well.

- Instrument_name_engraver
- Prints the name of the instrument (specified by
Staff.instrument and Staff.instr ) at the left of the staff.
Properties (read)
instr (markup)
- see
instrument
instrument (markup)
- If
Instrument_name_engraver
is
added to the Staff translator, then the instrument property
is used to label the first line of the staff and the instr
property is used to label subsequent lines. If the
midiInstrument property is not set, then instrument
is used to determine the instrument for MIDI output.
This engraver creates the following grobs:
InstrumentName.
- Piano_pedal_engraver
- Engrave piano pedal symbols and brackets.
Music types accepted:
abort-event and pedal-event
Properties (read)
pedalUnaCordaStrings (list)
- see pedalSustainStrings.
pedalSustainStrings (list)
- List of string to print for sustain-pedal. Format is
(UP UPDOWN DOWN), where each of the three is the string to print when
this is done with the pedal.
pedalSostenutoStrings (list)
- see pedalSustainStrings.
This engraver creates the following grobs:
SostenutoPedal, SostenutoPedalLineSpanner, SustainPedal, SustainPedalLineSpanner, UnaCordaPedal and UnaCordaPedalLineSpanner.
- Rest_collision_engraver
- Handles collisions of rests.
This engraver creates the following grobs:
RestCollision.
- Collision_engraver
-
This engraver creates the following grobs:
NoteCollision.
- Staff_symbol_engraver
- create the constellation of five (default) staff lines.
This engraver creates the following grobs:
StaffSymbol.
- Time_signature_engraver
- Create a TimeSignature whenever
timeSignatureFraction changes
This engraver creates the following grobs:
TimeSignature.
- Clef_engraver
- Determine and set reference point for pitches
Properties (read)
explicitClefVisibility (procedure)
- visibility-lambda function for clef changes.
clefOctavation (integer)
- Add
this much extra octavation. Values of 7 and -7 are common.
centralCPosition (number)
- Place of
the central C, measured in half staffspaces. Usually determined by
looking at clefPosition and clefGlyph.
clefGlyph (string)
- Name of the symbol within the music font
clefPosition (number)
- Where should
the center of the clef symbol go? On systems with an odd number of
stafflines, the value 0 puts the clef on the middle staffline; a
positive value shifts it up, a negative value shifts it down. The
unit of this distance is the half staff space.
This engraver creates the following grobs:
Clef and OctavateEight.
- Dot_column_engraver
- Engraves dots on dotted notes shifted to the right of the note.
If omitted, then dots appear on top of the notes.
This engraver creates the following grobs:
DotColumn.
- Separating_line_group_engraver
- Generates objects for computing spacing parameters.
This engraver creates the following grobs:
SeparatingGroupSpanner and SeparationItem.
- Volta_engraver
- Make volta brackets
Properties (read)
stavesFound (list)
- list of all staff-symbols found.
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 .
.
repeatCommands (list)
- This property is read to find any command of the form (volta . X), where X is a string or #f
This engraver creates the following grobs:
VoltaBracket.
- Font_size_engraver
- Puts fontSize into font-relative-size grob property.
Properties (read)
fontSize (integer)
- Used to set the relative size of all grobs
in a context. This is done using the
Font_size_engraver .
- 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 (read)
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.
.
This engraver creates the following grobs:
BarLine.
- Output_property_engraver
- Interpret Music of Output_property type, and apply a function to any Graphic objects that satisfies the predicate.
Music types accepted:
layout-instruction
- Axis_group_engraver
- Group all objects created in this context in a VerticalAxisGroup spanner.
Properties (read)
extraVerticalExtent (pair of numbers)
- extra vertical extent, same format as MinimumVerticalExtent
minimumVerticalExtent (pair of numbers)
- minimum vertical extent, same format as VerticalExtent
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 .
This engraver creates the following grobs:
VerticalAxisGroup.
