# Tuplets

A tuplet is a group of notes with an irregular duration to what's permitted by the given time signature.

**Figure 1: **A crotchet triplet.

Every tuplet has a number written with it which indicates **how many irregular units the tuplet contains**, as well as **how many units of the regular rhythm the duplet will span for**:

**Figure 2: **Our crotchet triplet spans for the duration of two regular crotchets.

The following is a list of tuplets with how many regular units each spans for:

Tuplet Name | Contains | Spans For | Diagram |
---|---|---|---|

Duplet | 2 | 3 | |

Triplet | 3 | 2 | |

Quadruplet | 4 | 6 | |

Quintuplet | 5 | 4 | |

Sextuplet | 6 | 4 | |

Septuplet | 7 | 4 | |

Octuplet | 8 | 4 | |

Nontuplet | 9 | 8 |

## Ratios

Sometimes a tuplet with an irregular ratio is required and can be written in place of the tuplet number.

**Figure 3: **A quaver quintuplet which spans for 8 regular quavers.

When interpreting a tuplet with a ratio, the left and right numbers indicate:

**Left number**: how many units the tuplet will contain; also gives the tuplet its appropriate name (e.g. duplet, triple, quadruplet, etc.)**Right number**: how many units of the regular rhythm the tuplet will span for
