Re: broken octaves

Dear Jay,
You wrote : "What should the output be? {c4 g' b, f' c g'} or {c4 g' b, fis' c g'}".
In my case, I'm much more interested in the second case "{c4 g' b, fis' c g'}". Because I'm writing mostly atonal music, I don't have to fear voice-leading teachers (and I think broken fifths have never been forbidden)!

It isn't trivial to get other intervals. For example if we're in the
key of c major and we do this: \brokenfifths #1 {c4 b c}

(don't let your voice leading teacher know you have this function :)

What should the output be? {c4 g' b, f' c g'} or {c4 g' b, fis' c g'}

Probably the first. So now let's do the same thing in f major: \key f
\major \brokenfifths #1 {f4 e f}

We'd probably want {f4 c' e, bes' f c'}. To do that we'd need some
information about the key to know we need a b flat here. Peter Chubb
has done some work here to get trills working on correct pitches for
midi (for that computer controlled clarinet project). (see
http://lists.gnu.org/archive/html/lilypond-user/2008-04/msg00686.html).
I never followed up with him about how he's noting key change events.
He might be processing a whole score at once to get this extra
information.
