Maybe the others' solutions are simpler. I would have thought there's
more to be done in Scheme ...

OK, probably I'd need several examples for different use cases (as I'm
not fully clear what you *really* want to do). But I'll show you one
pattern that I like pretty much: Actually it's one set-up and two
patterns/uses
###
musicA.ily:
violin = {
c''1
}
viola = {
c'1
}
cello = {
\clef bass
c1
}
###
musicB.ily:
violin = {
d''1
}
viola = {
d'1
}
cello = {
\clef bass
d1
}
###
violinStaff.ily
violinStaff = \new Staff \violin
### etc. violaStaff.ily and celloStaff.ily
###
partViolin.ily
\include "violinStaff.ily"
\bookpart {
\score {
\violinStaff
}
}
### etc. for viola and cello
###
score.ily
\include "violinStaff.ily"
\include "violaStaff.ily"
\include "celloStaff.ily"
\bookpart {
\score {
<<
\violinStaff
\violaStaff
\celloStaff
>>
}
}
Now your actual main.ly:
\include "musicA.ily"
%\include "musicB.ily"
\include "partViolin.ily"
%\include "partViola.ily"
%\include "partCello.ily"
\include "score.ily"

Now you can:
- comment out one of the alternative music files (using A or B)
- comment out any combination of part/score files.
The key to this is that you define alternative music files with
variables of the same name. Then you define scores/parts etc. that *use*
these variables. If you set this up properly you can easily switch
between musics and scores.
Depending on the use case one can make this even more sophisticated by
plugging in "adaptor" files.
