Beam objects are created by: Auto_beam_engraver, Beam_engraver, Chord_tremolo_engraver and Grace_beam_engraver
Standard settings:
gap
(dimension, in staff space):0.8
Size of a gap in a variable symbol.
positions
(pair):#<simple-closure #<simple-closure (#<procedure chain-grob-member-functions (grob value . funcs)> (#<primitive-procedure cons> 0 0) #<primitive-procedure ly:beam::calc-least-squares-positions> #<primitive-procedure ly:beam::slope-damping> #<primitive-procedure ly:beam::shift-region-to-valid> #<primitive-procedure ly:beam::quanting>) > >
Pair of staff coordinates (
left
.
right)
, where both left and right are in the
staff-space unit of the current staff.
concaveness
(number):ly:beam::calc-concaveness
A beam is concave when its inner stems are
closer to the beam than the two outside stems. This number is a
measure of the closeness of the inner stems. It is used for damping
the slope of the beam.
direction
(direction):ly:beam::calc-direction
If side-position is 1 (#X), then this property determines if the object is placed #LEFT, #CENTER or #RIGHT with respect to the other object. Otherwise, it determines if the object is placed #UP #CENTER or #DOWN. Numerical values may also be used. #UP=1, #DOWN=-1, #LEFT=-1, #RIGHT=1, CENTER=0 but also other numerical values are permitted.
beaming
(pair):ly:beam::calc-beaming
Pair of number lists. Each number list specifies which
beams to make. 0 is the central beam, 1 is the next beam toward the
note etc. This information is used to determine how to connect the
beaming patterns from stem to stem inside a beam.
stencil
(unknown):ly:beam::print
The symbol to print.
clip-edges
(boolean):#t
Allow outward pointing beamlets at the edges of beams?
thickness
(number):0.48
Line thickness, generally measured in
line-thickness
.
neutral-direction
(direction):-1
Which direction to take in the
center of the staff.
beamed-stem-shorten
(list):'(1.0 0.5 0.25)
How much to shorten beamed stems,
when their direction is forced. It is a list, since the value is different
depending on the number flags/beams.
damping
(number):1
Amount of beam slope damping.
auto-knee-gap
(dimension, in staff space):5.5
If a gap is found between note heads
where a horizontal beam fits that is larger than this number, make a kneed beam.
font-family
(symbol):'roman
The font family is the broadest category for selecting text fonts. Options include: sans
, roman
This object supports the following interfaces:
staff-symbol-referencer-interface, spanner-interface, beam-interface and grob-interface
