triple metre

Triple metre (or 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 3/4 and 9/8 being the most common examples. The upper figure being divisible by three does not of itself indicate triple metre; for example, a time signature of 6/8 usually indicates compound duple metre, and the 12/8 sections of Beethoven's Missa Solemnis are compound double with a primary division of four to the bar.
