TL;DR version of the question: How could I define an accidental style that
behaves mostly like neo-modern, but also avoids repeating accidentals
within a beamed group?
Full explanation why --
I have a cadenza which, according to Frescobaldi's duration counter, spans
59 quarter notes. It's in a free-chromatic style, so accidentals are very
important. Because it's in \cadenzaOn ... \cadenzaOff, accidentals are
remembered and not repeated basically "forever" within this stretch of
time.
If it were a C instrument, it would be easy: I would sprinkle "!"
throughout, wherever I want to see the accidental but it isn't printed by
default. But it's actually for clarinet in A... so I write the music
variable in concert pitch, and then use \transpose a c' in the layout file
for the part. Then, some of the accidentals that had to be forced for the
score in C end up forcing a natural-sign in the part, which looks dumb.
It turns out that most of the cadenza looks okay if I use neo-modern
accidental style, *but* there's one exception: fast notes that alternate
between two pitches. See the example pasted below:
#1 is the appearance I want (first bar is concert pitch, second bar is
transposed).
#2 illustrates the problem I described above. Forcing the second "cs!"
causes a confusing natural sign to be printed.
#3 The default accidental style "works," but doesn't scale up nicely to a
59-beat cadenza (because it will hide an accidental that appeared ten whole
notes ago).
#4 Neo-modern is "acceptable," the third sharp is really terribly fussy.
A nice middle ground between "remember accidentals for the whole cadenza"
and "remember accidentals only from the immediately preceding note" would
be to remember accidentals within a beamed group. Is there any way to hack
this up in scheme, say?
Thanks,
