Hi,
you likely know lily breaks only at matching BarLines.
So you have to insert a \bar "" at appropriate place. Which is tricky
here, because there is _no_ appropriate place.
Well, then create one, i.e.
instead of the original event, insert same simultaneous music like
<< e { s \bar "" s } >>
and then figure out which duration the first skip must have.
Which is tricky as well. For that purpose I use:
ctxMom =
\applyContext
#(lambda (ctx)
(format #t "\nin context~a: ~a" ctx (ly:context-current-moment ctx)))
and insert \ctxMom where I wrote \break (below I've did it in
FifteenHarpsUpper) and before the second skip of the inserted
simultaneous music in FifteenFlute.
Now I can scale the duration of the first skip until both values of
\ctxMom match.
