Noreen, I've been meaning to read up on all this and get back to you with apologies if appropriate. Really I have.

I have no problem with Mbo's and MMarios's first posts above. But I'm surprised you've let Mbo's second post go unchallenged. Can it really be that a single jig is 3/8 and a double jig 6/8? I could see the logic in this, but I've seen too many 6/8 jigs listed as "single" to be confident about it. On the other hand I still have some difficulty with your teaching, that a single jig is 6/8 but applied in a somehow different, and vaguely defined, rhythm, closer to "Half a pound of tuppeny rice..." (as someone else put it) than "pat a cake, pata cake..." Such a distinction would not need to affect the dance, and seems to be so fine as to be not worth drawing.

For the moment I remain puzzled.
