Related to my other question of note names I am wondering if it is possible to maybe write a mapping function of some sort for pitches?
I know there is transpose like shown here: https://lilypond.org/doc/v2.22/Documentation/web/text-input <https://lilypond.org/doc/v2.22/Documentation/web/text-input> \transpose f c' \hornNotes What I need, I think, is a way to write a “riff” let’s say and then transform it differently for different parts/instruments each of which would have a static mapping from the notes in the riff to the notes in the different parts. \version "2.20.0" riff = { c' r d' r } << \new Staff \riff % \new Staff \transformOne \riff \new Staff { e' r g'' r } % \new Staff \transformTwo \riff \new Staff { g'' r a'' r } >> Where transformOne would map c’ to say e’ and d’ to g’’. TransormTwo would map c’ to g’’ and d’ to a’’. I put what I would like to write in comments and what it would look like after. Writing the mapping function in scheme is fine I suppose. Or maybe some data structure like a map given to a single scheme function?
