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.
