Hi Phil,
Below is a modified snippet showing some things I would do in your situation.
(Note there are other ways of accomplishing the same things!)
1. I’ve defined custom contexts: a MySambaStaff context for shared
characteristics, and individual contexts (TamborinStaff, PulseStaff, BothStaff)
for characteristics specific to each type of staff. This allows easier code
maintenance and reuse, and (IMO) makes the code a lot easier to read.
2. I used a GrandStaff to get the span barlines.
3. I tried using \partCombine for the BothStaff music, but it threw an error.
Don’t have time to chase it down, but that’s almost certainly what you’ll
want/need to use here, in order to have notes and rests “merged” correctly.
Hope this helps!
Kieren.
