Answer:
Meter
Step-by-step explanation:
Meter is grouped into twos or maybe threes. It is the gathering of beats into regular groups, if it is in twos we call it a duplex and if they are in threes we call it a triple.
Meters tells us how the beats are organized, meters that are organized into groups of two are the duple beats, these ones are alternating between weak and strong beats. But if the beat is sorted into groups of 3 they are a triple meter
