Re: pitch-class sets in lilypond

[Stefan Thomas]

Dear community,

this is so far my module for working with pitch-class sets.

If You want to try it, You should save the 2 files in the same folder.

I've added a snippet in Frescobaldi, which  works fine (at least for me):

-*- python;

import sys

sys.path.append('/yourfolder/stefanspcs')

import stefanspcs

text = stefanspcs.get_prime_from_lily(text)

text = stefanspcs.get_lilyfrom_prime(text)

print(text)

You can select some music (pitches only, no durations, and so on) and You will see the prime-form when You run Your the above qwoted

In this way You can do some other things with this module, if You're interested.

Best,

Stefan
