Duple meter refers to a rhythm with two beats in each measure. The time signature can be divided by two, and the first beat of each measure is stressed.
Duple meter can also be explained as the division of longer beats into two equal shorter beats called microbeats. Examples of duple meter include 2/2, 4/4 and 6/8. Many different types of meters exist in music, including triple meter, quadruple meter and quintuple meter. Rhythm and meter are usually explained together, even though rhythm can be perceived subjectively. For example, a measure with a time signature of 6/8 can be heard in the same way as a measure with a time signature of 3/4, because the pairing of their beats can create similar rhythms.
