People,
I am doing my own Alternative Notation for Classical Guitar and with a
lot of help from Paul Morris am making good progress. I was about to
write a little Ruby script to generate random notes (400 == 100 bars)
within different ranges to practise jumping around the fretboard but
it occurred to me that I might be able to do this in Scheme - which
would help further the cause of learning for Lilypond. Is this a
sensible thing to do or should I just do it with ruby and plug the
results into a .ly file?
A bit sloppy:
\new Voice {
$@(let ((notes (ly:music-property #{ <c des d es e f fis g gis a bes
b> #}
'elements)))
(map (lambda (x) (list-ref notes (random (length notes)))) (iota
400)))
}
Amazing! OK, now to try and understand it . .
Thanks!
Phil.
