Is it possible to do something just with the first and last notes of
music within? Can they be extracted from music as from a list? (Hence
my reference in the original post to car and cdr)?
In music-functions.scm, you have some useful functions. Here an
extract-music is used.
%%%%%%%%%%%%%%%
music = \relative { c2->\f d e <e g c>2-> }
#(let ((mylist
(extract-music music
;(lambda (evt)(eq? (ly:music-property evt 'name) 'NoteEvent)))))
(lambda (evt)(memq (ly:music-property evt 'name)
'(NoteEvent EventChord))))))
(display-scheme-music (car mylist))
(display " ----\n")
(display-scheme-music (last mylist)))
%%%%%%%%%%%%%%%%
NB
Aleksandr, sorry for the double messages.
