In Music a tuplet is any consecutive group of notes with an individual Value more or less than half as long as the next larger note value. This is usually indicated with a horizontal (or nearly horizontal) bracket with a number over a tuplet indicating how many notes of the same altered value (or duration) are to be performed. EXPLANATION The most common tuplet is the triplet ( G. ''triole''), shown at right. Whereas normally two Quarter Note s are the same Duration as a Half Note , three triplet quarter notes total that same duration, so the duration of a triplet quarter note is 2/3 the Duration of a standard quarter note. Similarly, three triplet Eighth Notes are equal in duration to one quarter note. If several note values appear under the triplet bracket, they are all affected the same way, reduced to 2/3 their original duration. TUPLET NOTATION If the notes of the tuplet are Beamed together, the bracket may be omitted and the number written above the beam, as shown in the second illustration. Occasionally the bracket is omitted when the notes are Slur red together. For other tuplets, the number indicates a of 4, but other times to mean 7 notes in the duration of 8. To avoid ambiguity, composers sometimes write the ratio explicitly instead of just a single number, as shown in the third illustration. In Compound Metre , even-numbered tuplets can indicate that a note value is changed in relation to the Dotted version of the next higher Note Value . Thus, two Duplet Eighth Note s (most often used in 6/8 Meter ) take the time normally totalled by three eighth notes, equal to a dotted quarter note. Four quadruplet eighth notes would also equal a dotted quarter note. The duplet eighth note is thus exactly the same duration as a dotted eighth note, but the duplet notation is more often used in compound meters. USAGE AND PURPOSE Tuplets can produce Irrational Rhythm s, especially Hemiola , or may be used as Polyrhythm s when played against the regular duration. They are Extrametric Rhythmic Unit s.
