Re: ly:pitch-alteration

[Freeman Gilmore]

This is where I got ly:pitch-alteration. from, but I do not know how
to use it:
http://x31eq.com/lilypond/

The Pitch Model

Pitches in Lilypond are a combination of the position on the staff,
and the alteration relative to the nominal at that position, as a
rational fraction of a 200 cent whole tone. Pitch names repeat every
1200 cent octave. You can create a pitch with ly:make-pitch and find
out about an existing pitch with ly:pitch-octave, ly:pitch-notename,
and            ly:pitch-alteration.            There's also
ly:pitch-steps, which is a combination of ly:pitch-octave and
ly:pitch-notename, and ly:pitch-semitones which can be risky in a
microtonal context.

Thank you, ƒg
