Dear community,
sorry, it's a bit an off topic: If You are not interested in
pitch-class set theory, You don't have to read the following.
I've worked on a python module dealing with pitch-class set theory as
I've read in "The structure of atonal music" by Allen Forte.
I know that there already exists some modules like that but I want to
integrate it in lilypond.
I'm still working on this module, but at the moment I can do:
* Getting the normal form and prime form of a pcs.
* Transposing and inverting a pcs
* Finding subsets of a pcs given in primeform.
I'm working on:
* Finding different kinds of similarity of pcs.
* Getting subcomplexes k and kh of a pcs.
* Finding primeform and so on, when pitches in lilypond-style are
given.
* Getting pitches in lilypond-style when pitches in midinote-nums
or as pcs are given.
Let me know it if You are interested. Maybee it's only something of
interest for nerdy persons like me, but maybee for others too.
I don't know if this is of use to you, but I created a bunch of
LilyPond routines for dealing with PC sets (like in Forte, but also
with a finer equivalence relation not identifying a set with its
inverse) last year. I attach it unchanged, as I don't have time to
clean it up at the moment; you'll probably want to uncomment some of
the routines at the end to see what the functions do.
I'm curious: You write that you are working on a Python module; how
does this integrate in LilyPond?
