Someone replied to my question (Why are Semibreves called Whole notes?) with the information that there are Breves whose duration is two semibreves. This is certainly true, but shouldn't these Breves be called Whole Notes, and the semibreves (since "semi" denotes "half", from presumably a latin root) be called half notes? At any rate, the question was asked facetiously. I suppose it's all rather arbitrary, and one could just as easily have called an eighth note a whole note. But all this was, as we know, before Einstein. (Or Doppler! Heh heh) Arch
