[Callers] Tempos for Contras (was Re: Tempo for Squares)

[Rich Goss]

LiveBPM indeed does not do well with waltzes.   No problem with jigs or reels.

> I don't know whether anyone has done careful systematic testing of liveBPM's accuracy on a varied range of contra dance music.  If anyone does, I'd be interested in knowing the result.  I have, however, seen liveBPM be seriously confused (if you'll pardon the anthropomorphism) about the tempos of waltzes, where the beats come in multiples of three.  I wouldn't be surprised if it could were sometimes similarly inaccurate about jigs, in which the beats subdivide in thirds.  For example, perhaps it would sometimes report a tempo of, say, 84 BPM for a jig whose real tempo is 84 * 4/3 = 112 BPM.
