Swing ratios and rhythmic feels

Swing ratios express the strength of the swing using beat units. For example, a swing ratio of 2:1 means the first note in each pair is twice as long as the second, creating a triplet swing.

A swing ratio of 1:1 means the music is played straight, while a swing ratio of 5:1 means each pair of notes is played as if they were sextuplets, with the first note in the pair lasting five divisions and the second note lasting one.

The following rhythmic feels and swing ratios are provided by default in Dorico Elements:

2:1 swing (fixed): Extends the first note in a pair of eighth notes to be twice as long as the second, creating a strict triplet 2:1 ratio. This is also known as a triplet swing. This ratio is maintained regardless of the tempo by default.
3:1 swing (fixed): Extends the first note in a pair of eighth notes to be three times as long as the second, creating a dotted eighth-16th ratio (dotted quaver-semiquaver). This ratio is maintained regardless of the tempo by default.
Heavy swing: Produces a tempo-dependent swing ratio of between 3:1 at low tempos and 1.5:1 at high tempos.
Light swing: Produces a tempo-dependent swing ratio of between 1.5:1 at low tempos and 1:1 at high tempos.
Medium swing: Produces a tempo-dependent swing ratio of between 2:1 at low tempos and 1.5:1 at high tempos.
Straight (no swing): Produces no swing, that is, even eighth notes in the ratio 1:1 at all tempos.

You can change the swing ratio used for specific sections and for individual players.
