Hi L-F! >> Is map-some-music the correct next move? > Yes.
Thanks! > I take it you're only asking for confirmation you're on the right track? :-) Correct. I’ll try to ask more specific questions when I need more than confirmation. > So I only suggest use the ly:pitch? predicate for pitchIn/pitchOut instead of > ly:music?. Good point. I *think* I eventually want to allow a set (array?) of pitches in/out, but for now, I’ll start the input as small as the output. Thanks!
