Re: Changing Staff organization

[Mailing Lists]

Essentially, it sounds like you want 3 staves of vocal music and one  
piano staff (two staves), but you want to hide the vocal staves when  
they are resting and ditto for the piano, right?  Create a score with  
5 staves, keeping the vocal and piano parts separate (rather than  
using the two piano staves for part of your choir), including rests  
(or skips) as appropriate.  Your piano parts will have ~20 bars of  
music followed by rests/skips/nothing;  your vocal parts will have  
~20 bars of rest followed by their music.  You can then put them in  
their respective PianoStaff or ChoirStaff blocks so they get the  
proper brackets.  Then include the following in your \layout block to  
hide the resting voices/piano:

        \context {
                \RemoveEmptyStaffContext
                \override VerticalAxisGroup #'remove-first = ##t                
                }

the first line in this context hides staves other than in the first  
system.  The second line also hides the first system, but, of course,  
is optional.

Lastly, you will probably want to insert \break at the point between  
the piano and choir parts to have a clean switch.  Since your example  
has this break mid-measure due to the pickup, use:
        \bar "||" \break
to allow the line break mid-measure.
