This function gives control over tuplet construction. The default arguments
a = 3
and b = 2
generates a triplet where three triplet notes,
each lasting for two thirds of a beat, take up two beats.
n} is used to describe the beat duration with the same fraction-of-measure denominator notation used for notes in
tabr` phrases,
e.g., 16th note triplet, 8th note triplet, etc.
If you provide a note sequence for multiple tuplets in a row of the same
type, they will be connected automatically. It is not necessary to call
tuplet()
each time when the pattern is constant.
If you provide a complete phrase object, it will simply be wrapped in the
tuplet tag, so take care to ensure the phrase contents make sense as part of
a tuplet.
