Additive vs. Divisive Rhythm

Wikis > Glossary > Additive vs. Divisive Rhythm

Additive versus divisive rhythms are two different categories of meter. Divisive rhythms feature larger rhythmic units that divide into smaller equal units, while additive rhythms feature large rhythmic units made up of smaller units joined end to end in a series of unequal units. For example, 5/8 is an additive meter because it is a combination of 2/8 and 3/8 back to back, and 4/4 is a divisive meter because it is a combination of two 2/4 units.
