Separating pitch and rhythm

[Siska Ádám]

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
