Hi,
I'm stuck again.
I've got a passage that's meant to be aleatoric: each player has 4 phrases and
4 held notes to be played in any order.
Barlines should not be synchronized. Vertical alignment is irrelevant. I've
done some searching this morning but I can't find anything about how to
convince LP to suspend rhythmic relationships and typeset several simultaneous
staves with completely independent horizontal spacing (but for only part of a
score). -- If one part has a whole note with fermata, and at the same "score
time," another part has running 16ths, the whole note doesn't need that much
space, but LP will align it with the fast notes. \cadenzaOn / \cadenzaOff won't
help with that.
Gould recommends frames for each unit. I tried David Nalesnik's (excellent)
frameEngraver, but ran into a little snag because some of the frames will cross
system breaks, and as currently written, the frames will be automatically
closed at the beginning and end of a system, so it's difficult to distinguish
between a frame that terminates at the end of the system and one that continues
into the next system. But I'm not sure if I'll really continue with that,
because of the rhythmic alignment problem.
Polymeter with more careful attention to beat count doesn't produce errors, but
it also doesn't produce reasonable system breaks. I can *almost* get that to
work by forcing system breaks and scaling durations of the long notes -- ugly
hack but might almost work.
Or do I need to break this into multiple scores? E.g.,
\score { ... conventionally notated ... }
\score { ... flute part aleatoric bit, suppressing first-system indentation ...
}
\score { ... oboe part aleatoric bit, suppressing first-system indentation ... }
... etc.
\score { ... more conventional notation ... }
That would certainly suspend horizontal alignment. Instrument staves would not
be interleaved, but interleaving them might be misleading anyway since it would
imply temporal relationships that don't exist.
Suggestions...? Been banging at this for an evening and a morning.
