I now wrote this:
#(define (transform chord m1 m2)
(let* ((note (car (ly:music-property chord 'elements)))
(dur (ly:music-property note 'duration))
(pitch (ly:pitch-notename (ly:music-property note 'pitch)))
(new (ly:music-deep-copy (if (= pitch 0) m1 m2))))
(make-music 'EventChord 'elements
(map (lambda (m) (ly:music-set-property! m 'duration dur) m)
(ly:music-property new 'elements)))))
pat = #(define-music-function (parser location m1 m2) (ly:music? ly:music?)
(make-music 'SequentialMusic 'elements
(map (lambda (m) (transform m m1 m2)) (ly:music-property
thePattern 'elements))))
thePattern = { c8 d16 c d8 c d16 c d8 c d }
so \pat <d e> <f g> also works.
But when in relative mode larger intervals are used, e.g.:
\relative c' { \pat c c' }
each c is put one octave higher. How can I get this to work so that every c
just stays in the same octave?
