Hi Tommy & others, >A ruler or tape measures the distance from a datum to a point of >interest, thus we count 0 at the start. >In music the first beat Makes a damn fine datum point. Music is time, continuously numbered with fractions etc. Counting is discrete integers and is more appropriate for sheep. Anyway, I want this as an option - no-one else would have to use it. But there is strong logic & practicality supporting it... Cheers, Thomas
