Embedded scheme questions

[Laurent Martelli]

Is is possible to actually build a sequence of notes within embedded
scheme code ? I would like to implement some kind of repeat-and-shift
that would repeat a block of music a number of times, shifting it by a
number of degree each time. From the apply hack exemples, I can only
tell how to modify some music.

\apply #(repeat-and-shift '(0 1 2 3 2 1 0)) { c e g }

would produce (in the key of C major) : 

        c e g  d f a  e g b  f a c  e g b  d f a  c e g


Also, I would like to implement an auto-fingering function. Is it
possible to add script to the note in scheme ?
