Hello,
I have a variation of a piece, where the first lines are played single
voice over two staves and the other lines are normal upper/lower staves.
To avoid a lot of silent rests I want to use the \autochange in the
PianoStaff for the first lines and append the other in the same score.
At first I have a problem, to setup the environment for the \autochange
as described in 2.2.1 (Common notation for keyboards/Changing staff
automatically). Instead of settng the low staff key I get an additional
one. Why do I get it and how it's done correct?
Second I want to combine both parts. I tried it as show in the third
score. This doesnt compile. Therefore I have commented it out. Can you
show me, how to write both, normal notation and \autochange in one
score? I would prefer to use the musical expression definitions used in
\score since these are in \included files.
Thanks,
Helge
