Dear List!
I’m still learning lilypond and working on a piece with long text instructions
that appear over a note or group of notes. So far I have managed to achieve
this by hacking off the stencils from text spanners and replacing them with the
line wrapped markup, but I feel there should be a neater solution out there
that I just haven’t thought or learned about. This hack has also reached it’s
limits because it has created the need for multiple simultaneous text spanners
(not in the example). While I could go further down the hack road by placing
additional spanners in separate voices with spacer rests or starting to destroy
trill spanners too, that would just increase the mess. Could you please point
me towards a tidier path? :)
Thanks a lot!
