Hi, I would expect that all three examples yield the sme output, but the middle with s1 seems to disturb the add lyrics algorithm.
Did I something wrong? %Begin example \version "2.24.4" melody = \relative c'' { a4~4 b4 c4 } words = \lyricmode { A -- B C } \score { << \new Staff { \melody } \addlyrics { \words} >> \layout { } } %Mixed up tie \score { << \new Staff { << \melody {s1} >> } \addlyrics { \words} >> \layout { } } \score { << \new Staff { << \melody {} >> } \addlyrics { \words} >> \layout { } } %End example Arne
