"Atholl Highlanders', for instance, needs to be played briskly with a dotted rhythm (ie as a pipe march rather than a jig) otherwise the musicians start falling asleep." (Dave McKenzie above)
Not much risk of folk falling asleep while dancing: we play it to dotted rhythm as part of a Military Two-step Set: quite tricky to get a' they dots in at dance speed! Different can o' haggis when played wi' dots!
