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
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.
