I've been slowly learning how to stamp my foot. It isn't something I used to do at all. Dick Hensold relayed a useful idea about it to me from David Greenberg the Cape Breton fiddler, who stamps his foot a lot. The foot is a bit like a metronome, but the point is that the accents in the tune DO NOT have to correspond to the stamps - the idea is that the tune flows around them, with the accents pushed or pulled, but the overall tempo doesn't change.

Good foot stamping takes practice.
