Hi List,
I have a file with the following functions defined:
beambreakOn = {
\set subdivideBeams = ##t
\set baseMoment = #(ly:make-moment 1/8)
\set beatStructure = #'(2 2 2 2)
}
beambreakOff = {
\set subdivideBeams = ##f
\set baseMoment = #(ly:make-moment 1/8)
\set beatStructure = #'(2 2 2 2)
}
when invoked inside a music expression, they set all beams greater than the
8th (that is, past the first) to break at the 8th note. This allows, for
example, the following expression (pseudo-code):
{ a32 b c d e f g16 }
to split neatly at the midpoint, clarifying the metric structure. The
problem is, later on in the piece I have the following command:
\compoundMeter #'((3 4 16))
and a measure with the contents (pseudo-code):
{ < f a c >8 < d fis a >16 < f a c > < g b d >8\fermata < d fis a >16 }
theoretically, this should automatically divide thus:
{ < f a c >8[ < d fis a >16] < f a c >[ < g b d >8\fermata < d fis a >16] }
but instead it divides:
{ < f a c >8[ < d fis a >16 < f a c >] < g b d >8\fermata[ < d fis a >16] }
Here's the whole thing in a MWE:
---------------------------------
\version "2.19.80"
beambreakOn = {
\set subdivideBeams = ##t
\set baseMoment = #(ly:make-moment 1/8)
\set beatStructure = #'(2 2 2 2)
}
beambreakOff = {
\set subdivideBeams = ##f
\set baseMoment = #(ly:make-moment 1/8)
\set beatStructure = #'(2 2 2 2)
}
\relative c' {
\time 4/8
%1
\beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata < a,
cis e >32 < a cis e > \beambreakOff
| %2
\compoundMeter #'((4 3 16))
< f' a c >8 < d fis a >16 < f a c > < g b d >8\fermata < d fis a >16
| %3
\time 4/8
\beambreakOn a32\( b cis dis eis8\) a,32\( b cis dis eis16\)\fermata < a,
cis e >32 < a cis e > \beambreakOff
}
---------------------------------
Is there a command I can insert after the first measure to allow the
\compoundMeter command to reset beam divisions as intended?
Cheers,
A
