Re: Slurs not being followed in one vocal part

[Jon Arnold]

Thanks all! Separating the voices did fix the problem. I used this score a long time ago and then updated the layout, so I feel like an update several years ago must have changed the behavior, which is interesting.

You need something more like:

choirPart = \new ChoirStaff <<
  \new Staff \with {
    midiInstrument = "choir aahs"
    instrumentName = "Soprano"
  } <<
    \new Voice { \barLiner }
    \new Voice { \soprano }
    \addlyrics { \sopranoVerse }
  >>
  \new Staff \with {
    midiInstrument = "choir aahs"
    instrumentName = "Alto"
  } { \alto }

I presume that \addlyrics gets totally confused when asked to
add lyrics to a construction like { << \soprano \barLiner >> }.
How would it know to use only the \soprano line?

Cheers,
David.
