any ideas how to get a more even - ot lets say rhythmic - distribution
of the notes with lyrics?
To add to Kieren’s suggestions:
– Obviously, fonts with an overall smaller width help. LilyPond’s
default (Century Schoolbook) isn’t the best choice in that regard.
– I even use a script to automatically tweak self-alignment-X for longer
syllables, see attachment. It greatly reduces the need for manual
intervention.
– <https://sourceforge.net/p/testlilyissues/issues/2456/> and
<https://sourceforge.net/p/testlilyissues/issues/2453/>: there’s a lot
of work to be done on lyrics, and Janek put some of it up as this
‘Lyrics project’, which unfortunately nobody has tackled yet…
