In music, counting is a system of regularly occurring sounds that serve to assist with the performance or audition of music by allowing the easy identification of the beat. Commonly, this involves verbally counting the beats in each measure as they occur. In addition to helping to normalize the time taken up by each beat, counting allows easier identification of the beats that are stressed. Counting is most commonly used with rhythm and form and often involves subdivision.
The method involving numbers may be termed count chant, "to identify it as a unique instructional process."
In lieu of simply counting the beats of a measure, other systems can be used which may be more appropriate to the particular piece of music. Depending on the tempo, the divisions of a beat may be vocalized as well (for slower times), or skipping numbers altogether (for faster times). As an alternative to counting, a metronome can be used to accomplish the same function.
Triple meter, such as 3
4, is often counted 1 2 3, while compound meter, such as 6
8, is often counted in two and subdivided "One-and-ah-Two-and-ah" but may be articulated as "One-la-lee-Two-la-lee". For each subdivision employed a new syllable is used. For example, sixteenth notes in 4
4 are counted 1 e & a 2 e & a 3 e & a 4 e & a, using numbers for the quarter note, "&" for the eighth note, and "e" and "a" for the sixteenth note level. Triplets may be counted "1 tri ple 2 tri ple 3 tri ple 4 tri ple" and sixteenth note triplets "1 la li + la li 2 la li + la li". Quarter note triplets, due to their different rhythmic feel, may be articulated differently as "1 dra git 3 dra git".
