Whether a meter is compound: its main pulses each divide into three, as in
6/8, 9/8, 12/8, or 6/4. Compound meters are those whose numerator is a
multiple of three greater than three, independent of the denominator. Meters
like 3/8 and 3/4 (simple triples, numerator 3) are not compound, and neither
is a signature whose TimeSignature.grouping selects the additive
reading (9/8 as 2+2+2+3).
