I am trying to tackle the swing music problem that someone posted about
earlier; it arises in traditional Irish music as well.
I’m blocked on detecting eighth-notes, though (or quavers for you Brits).
It seems like this should work (event is an EventChord):
(eq?
(ly:music-property
(car (ly:music-property
event
'elements))
'duration)
(ly:make-duration 3 0 1 1))
However, this seems to return #f all the time, regardless of what event
actually has. If I use (eq? (ly:duration-log ...) 3), it works, so I
know I am getting a duration. Do I have to actually compare
duration-log, duration-dot, and duration-factor? That seems a bit annoying.
What am I missing?
Thanks in advance,
Chris
