Hi
Nick (cc'ing lilypond-user@ this time),
Here's
a solution for that excerpt. The specific solution for blanking
out the staff is to use \stopStaff and \startStaff; between
those two commands, you can use \override Staff.StaffSymbol
#'transparent to ##t and likewise Staff.BarLine #'transparent =
##t.
I
just did the repeat text, fingerings, and circled numbers
because I haven't messed with those much before and I was
curious to see if I could get them working. If anyone knows how
to align a fingering right against a note when there's an
accidental present elsewhere in the Staff's note column at that
moment in musical time, I'd love to know how it's done. This
also generates a warning about already having a volta spanner
that I wasn't sure how to get rid of, but that doesn't affect
the output.
