It's not only about extenders, it's about aligning lyrics to a melody in general. Moreover, the associatedVoice property can be used to switch voice assignment etc.
The difference between setting associatedVoice to a nonexistent voice and setting it to ##f (resp. not setting it at all) is that in case of ##f, the lyrics won't be aligned to /any/ melody and you'll have to explicitly specify durations. All in all, it's the difference between using \lyricsto "..." and not using \lyricsto "...", like in \lyricmode { Not4 a -- ligned to a mel2 -- o -- dy } All the best, Torsten -- Sent from: http://lilypond.1069038.n5.nabble.com/User-f3.html _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
