I also note Timothy's useful comments re the Notation Reference, so
thank you both. I'm still a little confused, though,,,
Is there any way to get Lilypond to distinguish between notes and
rests? For instance, if I use the suggested form:
\set Timing.beamExceptions = \beamExceptions { 8[ 8 8 8] | 16[ 16 16
16] 16[ 16 16 16] }
then that achieves what I originally asked for, which is for the
beaming in a bar of quaver notes to be [c8 c8 c8 c8]. This is fine for
the piece I am currently setting.
But suppose I had some bars with rests - for instance | c8 c c r | r c
c c |. With the new beamingExceptions setting, I find that these are
now beamed as | [c c c] r | and | r [c c c] |. I would perhaps,
though, want them to appear as | [c c] c r | and | r c c[ c] | (i.e.
without a beam crossing the middle of the bar).
Is there a way to get this result with automatic beaming and still keep
my new [c c c c] beaming, or would it have to be done with manual
beams?
