Hi Graham,

you will most likely have a PianoStaff for the keys and a ChoirStaff or StaffGroup (or the like) for the choir. You can consist a grouping context (ChoirStaff,StaffGroup,...) with:


\consists "Keep_alive_together_engraver"


That way the whole group disappears only, if all child-context would disappear on there own.


IIRC the PianoStaff context consists this engraver per default.

Many thanks Jan-Peter,
this works perfectly.  For the benefit of others, I applied it (after a short struggle) thus:

\score {
    <<
    \new ChoirStaff
    <<
      \set ChoirStaff.systemStartDelimiter = #'SystemStartBar
      \sopranoVoicePart
      \altoVoicePart
      \tenorVoicePart
      \bassVoicePart
    >>
    \pianoPart
  >>
  \layout {
      \context { \ChoirStaff \consists Keep_alive_together_engraver }
      \context { \RemoveEmptyStaffContext }
  }
}
