## Section4.5Tuplets

Tuplet is a generic term that describes a grouping of notes that would not normally occur within a beat.

A quarter note naturally divides into two eighth notes or four sixteenth notes. A triplet is a grouping of three eighth notes that occurs within the span of the quarter note. A quintuplet would be a grouping of five sixteenth notes to occur within the span of one quarter note. It is not uncommon to see quintuplets, sextuplets, and septuplets.

If you write a piece of music that naturally has a triplet division to the beat, you should use $$\begin{smallmatrix}6\\8\end{smallmatrix}$$, $$\begin{smallmatrix}9\\8\end{smallmatrix}$$ or $$\begin{smallmatrix}12\\8\end{smallmatrix}$$ depending on the number of beats in each measure.

In compound meter, a duplet is a grouping of two eighth notes to occur within the span of a dotted quarter note and a quadruplet is a grouping of four eighth notes to occur with the span of a dotted quarter note.
