#### 3.1.10 Tuplets

Tuplets are made out of a music expression by multiplying all durations with a fraction

         \times fraction musicexpr

The duration of musicexpr will be multiplied by the fraction. The fraction's denominator will be printed over the notes, optionally with a bracket. The most common tuplet is the triplet in which 3 notes have the length of 2, so the notes are 2/3 of their written length

>          g'4 \times 2/3 {c'4 c' c'} d'4 d'4

The property `tupletSpannerDuration` specifies how long each bracket should last. With this, you can make lots of tuplets while typing `\times` only once, saving lots of typing. In the next example, there are two triplets shown, while `\times` was only used once

>          \set tupletSpannerDuration = #(ly:make-moment 1 4)
>          \times 2/3 { c'8 c c c c c }

The format of the number is determined by the property `tupletNumberFormatFunction`. The default prints only the denominator, but if it is set to the Scheme function `fraction-tuplet-formatter`, num:den will be printed instead.

##### Predefined commands

`\tupletUp`, `\tupletDown`, `\tupletBoth`.

##### Bugs

Nested tuplets are not formatted automatically. In this case, outer tuplet brackets should be moved manually, which is demonstrated in input/regression/tuplet-nest.ly.
