Hi all,

The documentation states: For vocal scores (hymns), there is no need to add  
“solo/a2” texts, so they should be switched off. However, it might be  
better not to use it if there are any solos, as they won’t be indicated. In  
such cases, standard polyphonic notation may be preferable.

I have seen SATB scores where the a2 notes have a up and down stem, but the  
solo notes just a up or down stem.  Thus distinguishing between solo and a2.

It would therefore be useful to have a command that would act like  
\partcombineAutomatic when there are two different notes of the same  
duration at the same time, and like \partcombineApart at any other time.   
Or am I missing something?

musicUp = \relative c' {f4 g c r}

musicUpDistinguishSolo = \relative c' {f4 \partcombineApart g c r}

musicDown = \relative c' {c4 g' r c,}

<<
  \new Staff \musicUp
  \new Staff \musicDown
  \new Staff \with { printPartCombineTexts = ##f } {
    \set Staff.instrumentName = #"solo or a2??"
    \partcombine \musicUp \musicDown
  }
  \new Staff \with { printPartCombineTexts = ##f } {
    \set Staff.instrumentName = #"New style"
    \partcombine \musicUpDistinguishSolo \musicDown
  }
