Hello Marc,
Thanks for teaching me this.
As it turns out, we’re better off specifying durations at crucial points to
avoid « inheriting » such default values, see:
c'4 d e f \notesToRests \fragment f'8 e c2
below.
JM
\version "2.19.32"
notesToRests =
#(define-music-function (music) (ly:music?)
(music-map
(lambda (m)
(if (eq? (ly:music-property m 'name) 'NoteEvent)
(make-music 'RestEvent
'duration (ly:music-property m 'duration))
m))
music))
\relative {
c'4 d e f \notesToRests { g a b2 g8 c } f e c2
}
\relative {
c'4 d e f \notesToRests \relative { g' a b2 g8 c } f' e c2
}
fragment = \relative { g'4 a b2 g8 c }
\relative {
c'4 d e f \notesToRests \fragment f'8 e c2
}
