Triple metre (or Am. triple meter, also known as triple time) is a musical metre characterized by a primary division of 3 beats to the bar, usually indicated by 3 (simple) or 9 (compound) in the upper figure of the time signature, with , and being the most common examples. In these signatures, beats form groups of three, establishing a triple meter feel in the music or song. The upper figure being divisible by three does not of itself indicate triple metre; for example, a time signature of usually indicates compound duple metre, and similarly usually indicates compound Quadruple meter.
Shown below are a simple and a compound triple drum pattern.

In jazz, this and other more adventurous metres have become more common since Dave Brubeck's album Time Out.May, Chris.

Triple time is common in formal dance styles, for example the sarabande, the minuet, the mazurka, the waltz and others.
Triple metre is rare in national anthems – the national anthems of Austria, the United Kingdom, Swiss Psalm, Greece, and the United States being notable exceptions.
