Hi All, I have this function to make a tone cluster:
%%%% \version "2.20.0" toneCluster = #(define-music-function (note1 note2) (ly:music? ly:music?) #{ << { #note1 } { \once\override NoteHead.stem-attachment = #'(0 . 0) \once\override Stem.length = #14 % <= Manually set. \once\override Stem.thickness = #7 #note2 } >> #}) % Test: { a' \toneCluster a a'' a' \toneCluster a cis'''' } %%%% How could I set the stem length automagically according to the pitch difference? Cheers, Pierre
