Type Alias TimeSignature

Optional additive grouping of the bar's main pulses, as the felt-beat lengths in pulses — e.g. [2, 2, 3] for a 2+2+3 reading of 7/8, or [3, 2] for 5/8. The entries must be positive integers summing to pulsesPerBar. When present, the head pulse of each group (other than the downbeat) is treated as a secondary strong pulse by metricWeight/isStrongBeat; when absent, all main pulses are weighted equally as flat, evenly divided pulses.
