fixed :) Thank you David it works perfectly.
I have one more question about how to split it in multiple score. But I'll
open another thread.

Well, I used music-clone instead of ly:music-deep-copy for 'elements and
the former cannot deal with a list. Sorry for that. Try
\version "2.19.81"
foo =
#(define-music-function (seq1 seq2) (ly:music? ly:music?)
(set! (ly:music-property seq1 'elements)
(map! (lambda (note)
(music-clone seq2
'elements (cons note
(ly:music-deep-copy (ly:music-property seq2
'elements)
(ly:music-property seq1 'elements)))
seq1)
seqI = { c b a }
seqII = { f g }
{\foo \seqI \seqII}

David I copied and pasted you code but it didn't compile. I changed
ly:music-properties to ly:music-property but it doesn't compile anyway.
This is the complete code:
\version "2.19.81"
foo =
#(define-music-function (seq1 seq2) (ly:music? ly:music?)
(set! (ly:music-property seq1 'elements)
(map! (lambda (note)
(music-clone seq2
'elements (cons note (music-clone (ly:music-property seq2
'elements)
(ly:music-property seq1 'elements)))
seq1)
seqI = { c b a }
seqII = { f g }
{\foo \seqI \seqII}
... and this is the error I get

Nope. You need to write
(ly:music-deep-copy (ly:music-property seq2 'elements))
instead of
(ly:music-property seq2 'elements)
here or you'll get surprising results whenever the result is changed in
place (like when transposing the result).
Incidentally, it might make sense to write instead
foo =
#(define-music-function (seq1 seq2) (ly:music? ly:music?)
(set! (ly:music-properties seq1 'elements)
(map! (lambda (note)
(music-clone seq2
'elements (cons note (music-clone (ly:music-property seq2 'elements)
(ly:music-property seq1 'elements)))
seq1)
That will take the structure of the respective sequences as templates,
so you can use <<...>> instead of {...} for either and have this
reflected in the result. Also <...> though that will make sense only
for the inner structure.

You should make a music-function:
\version "2.19.81"
foo =
#(define-music-function (seq1 seq2) (ly:music? ly:music?)
(make-sequential-music
(map (lambda (note)
(make-sequential-music

I have a sequence of notes and a music expression.
How could be done a function concatenating each element of the sequence

For instance, if the sequence is {c b a } and the music expression is {

c f g
b f g
a f g
Don't known what Lilypond version you have. This should work in 2.18 and
2.19
%%
#(define (foo seq1 seq2)
(map (lambda(note)
;(ly:music-deep-copy ;; if music is re-used
(make-sequential-music
(cons note (ly:music-property seq2 'elements
(ly:music-property seq1 'elements)))
seqI = { c b a }
seqII = { f g }
#(for-each display-lily-music (list seqI seqII))
#(display "=>\n")
#(for-each display-lily-music (foo seqI seqII))
%%%
Output :
{ c4 b4 a4 }
{ f4 g4 }
=>
{ c4 f4 g4 }
{ b4 f4 g4 }
{ a4 f4 g4 }
Good week.

concatenating notes with a music expression
I have a sequence of notes and a music expression.
How could be done a function concatenating each element of the sequence
with the music expression?
For instance, if the sequence is {c b a } and the music expression is { f g
} I would like to obtain
c f g
b f g
a f g
