Definition:

A triplet – a type of “tuplet” – is a group of three notes played inside another note-length; a portion of musical time that’s been split rhythmically into three equal parts¹. A triplet is identified by a small ‘3’ above or below its note beam, bracket, or slur (see image).

A triplet group’s total duration is equal to two of the original note-values contained within². For example, an eighth-note triplet spans two eighth note beats (one quarter-note); a quarter-note triplet spans the length of a half-note; and so on:

• ? Hear eighth-note triplets in 4/4 time
  Triplets occur on each quarter-note beat.
• ? Hear quarter-note triplets
  Two groups of triplets fit in one measure of 4/4 time.

? (View notation for the above examples)

¹  A triplet’s contents may not always appear equal; they can be modified in value, so long as the total length of the note-grouping remains intact; learn more:

²  Any individual note or rest inside a triplet has been reduced to 2/3 its original length.
