Re: elegant compound time signatures

[Graham Percival]

Trevor: a top-post in this case makes the thread really bloody
confusing to read.  (I know this email compounds the problem, but
I've given up on this thread)

Hans: at the risk of sounding grumpy, did you try compiling my
example?  I believe it does everything you want.

Trevor again: at the risk of sounding even grumpier, your solution
produces the same output as mine, but uses the much more confusing
#(override-beam...) stuff.  \set beamGrouping is much easier to
understand and use.

Cheers,
- Graham
