Separating pitch and rhythm
Dear List,
is there an effective way to separate the pitches and the rhythms in a voice?
I'm thinking about something like defining a variable consisting only of
rhythms:
Rhythm = {
\time 4/4
4 4 4. 8
8 8 4 4 8 8
2 4 8 8 ...
}
and then apply this to different sequences of pitches:
Seq1 = {
\clef treble
c d e f
g a g f e d
c e g c ...
}
Seq2 = {
\clef bass
c b a g
f e f g a b
c g e c ...
}
(etc.)
The purpose is: I'm engraving a long, homophonic section in an orchestral
piece, where cca. 30 instruments play the same rhythms, but with different
pitches.
Thanks for any ideas,
Ádám

Sounds like it would be a cool feature if it existed. Not sure how

}
And then everything else would be forced into that structure. Perhaps
it can be combined. Specify the rhythm as you suggest and add a flag
(strict?) to specific parts to apply the rhythm as you suggest. That
way you don't have to have all or nothing. Some parts can follow the
strict rhythm and other parts can deviate as long as it fits.
Not sure if key and tempo belong in structure.

Well the second one is possible now. You can do linebreaks, repeats and, I
believe articulations as well by simply putting them in a separate definition
block like this:
structure = {
s1*4 \break
\repeat volta 2 { s1*2}
\alternative {
{ s1 }
}
s1
\bar |.
}
...and then combining them later with the musical layer with something like:
\score{
\context Staff
\music
\structure
}
