Hi William,
In fact, the example does everything I want, except I can't figure
out how to get bar numbers to show up! Ideally one per bar at the
top, but a bar number at the beginning of each system would be almost
as good!
Try the following additions:
global = {
\key c \major
\time 4/4
\bar "" % Permits bar 1 to get a bar number
}
and
scoreAViolinIPart = \new Staff \with {
instrumentName = "Violin I"
midiInstrument = "violin"
\consists "Bar_number_engraver" % Show bar numbers
\override BarNumber.break-visibility = #'#(#t #t #t) % Show a bar
number for every bar
barNumberVisibility = #all-bar-numbers-visible % Also show number
for bar 1
} \scoreAViolinI
Best
Lukas
PS. Folks on the list advocating separation of content and layout will
probably object to the construction of having a \new Staff \with { ...
} inside a _music_ variable, but of course it's possible to do it that
way.
