You can't call music functions directly from Scheme code. You have to either wrap the call in #{ #} or use `ly:music-function-extract` to extract the procedure itself and call that.
In recent development versions, that’s obsolete. E.g. { #(bar "|.") } and { ##{ \bar "|." #} } are now completely equivalent. Best, Simon _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
