 A duplet – a type of tuplet – is a note-grouping of two, which fits into the length of three of its note-type. For example:

  • Eighth-note duplets span the length of three normal (or “straight”) eighth-notes.
  • Sixteenth-note duplets span the length of three 16th notes (or a dotted eighth-note).

Note that while many tuplets split a beat into smaller parts, the duplet expands the length of its notes. For example, a triplet makes three notes span two, therefore reducing each note within to 2/3 its original length. The duplet forces two notes to take the space of three, making them to equal 1 1/2 their original lengths.

Duplets create a temporary irrational rhythm within a song. While rarely used, they can be seen in bridges, but are most frequently used in jazz piano.

  • The 6 Enharmonic Key Signatures
    If you’re familiar with the circle of fifths (or you just know your way around the key signatures) you may have noticed a few anomalies. Some keys – like B-sharp and F-flat major – are seemingly absent, while others go by two names
  • The Inefficient Keys
    The circle of fifths shows only the working scales. But, if we expand on its pattern, we can see that it’s actually more of an infinite spiral, so there’s no end to the possibilities of musical scales.
