Triple metre
Triple metre (US: triple meter; also known as triple time) is a musical metre characterised 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 34, 38 and 98 being the most common examples. In these signatures, beats form groups of three, establishing a triple meter feel in the music or song.
