Ever wonder why a military march makes you stomp in twos (LEFT-right, LEFT-right), while a Viennese waltz sways gently in threes (ONE-two-three, ONE-two-three)?
That unique physical groove comes from meter, the regular grouping of musical pulses into repeating patterns of strong and weak beats.

Simple Meter: Dividing by Two

In simple meter, each main beat naturally splits into two equal parts. If you tap your foot on the beat, your foot goes down on the number and up on the & (and).
A time signature at the start of the staff tells you how the meter is built: the top number shows the number of beats per measure, and the bottom number shows which note value gets one beat (a 4 means a quarter note).
To count rhythms in simple meter, use the standard system: whole beats are numbers (1, 2, 3, 4), eighth notes add & (1 & 2 &), and sixteenth notes add e and a (1 e & a).
For example, in 2/4, a measure with one quarter note followed by four sixteenth notes is spoken aloud as 1, 2-e-&-a.
What happens when music has a rolling, bouncy sway that does not divide into twos?

Compound Meter: Dividing by Three

In compound meter, each main beat is a dotted note that naturally divides into three equal parts instead of two.
In 6/8 time, the top number counts six fast eighth-note pulses, but your body actually feels two dotted-quarter beats per measure (a compound duple meter).
