Re: ChoirStaff with spanning bar lines at breaks

[Lukas-Fabian Moser]

\version "2.22.1"

\layout {
  \context {
    \ChoirStaff
    \consists Span_bar_engraver
    \override SpanBar.break-visibility = ##(#t #f #f)
  }
}

... or, if you want to have the illusion of being able to talk to 
LilyPond in English, equivalently:

\layout {
  \context {
    \ChoirStaff
    \consists Span_bar_engraver
    \override SpanBar.break-visibility = #end-of-line-visible
  }
}
