I'm trying to define a music function that transposes a chord and
a melody multiple times. But for some reason, the transposition is
done only once.
Here's my attempt:
repeatpattern =
#(define-music-function (parser location chord
pattern) (ly:music?
ly:music?)
#{
<<
\new ChordNames {
\transpose c d { #chord
}
\transpose c e { #chord }
}
\new Staff
{
\transpose c d { #pattern }
\transpose c e
{ #pattern }
}
>>
#})
\score {
\repeatpattern { c1 } { c'4 d' e' r }
}
Any ideas for why this is not working and how to fix it? (i.e.,
it
should transpose "c d e" into "d e f#" and "e f# g#", not into "f#
g#
a#").
