David, This looks fantastic. I'll play with it.

Re: Generate Random Pitches and Accidentals?
I have not read the messages in the thread, so may be anybody has already provided a solution to your problem. I always planned to try http://projectabjad.org/ for algorithmic (fractal) composition of music, never found the time. Check it, may be abjad is of use for you? (There is another program equally named Abjad - The Arabic Alphabet Learning System.)

There is a discussion of generating random notes in the comments of this
blog post:
http://lilypondblog.org/2014/03/music-functions-1-getting-to-grips-with-scheme-in-lilypond/
The example code is:
#(define myList
(list
#{ b2 #}
#{ c'2 #}
#{ d'2 #}
#{ e'2 #}))
mySchemeFunction =#(define-music-function (parser location) ()
(list-ref myList (random (length myList
mySetSeed = #(define-void-function (parser location) ()
(let ((time (gettimeofday)))
(set! *random-state*
(seed->random-state (+ (car time)
(cdr time))
{
\mySetSeed c'4 \mySchemeFunction c' \mySchemeFunction c'
\mySchemeFunction c' \mySchemeFunction c' \mySchemeFunction c'}

Unfortunately it does not, and I don't know SCHEME well enough to know what to do, or even start.

I did something like this once a while back, though it was easier and faster for me at the time to just load up Reaper, use a plugin/script to generate the random note data, and just export out the notation to pdf or musicxml. Then it was all LilyPond after that for my project. Does this have to be contained *fully* in LilyPond for your purposes? Give us some more info please :) ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
