Rhythmic unit

From Wikipedia, the free encyclopedia

A rhythmic unit is a durational pattern which occupies a period of time equivalent to a pulse or pulses on an underlying metric level, as opposed to a rhythmic gesture. Rhythmic units may be classified as:

1. Metric: even-note patterns, such as steady eighth notes or pulses.
2. Intrametric: confirming patterns, such as dotted eighth-sixteenth note and swing patterns.
3. Contrametric: non-confirming, or syncopated patterns.
4. Extrametric: irregular patterns, such as tuplets.
