What tempo is swing music?
The swing ratio can be as high as 3.5:1 at comparatively slow tempi around 120 bpm. When the tempo is fast the swing ratio reaches 1:1, that is, the eighth notes are performed evenly. The duration of the short note in the long-short pattern is approximately constant (≅ 100 ms) for medium to fast tempi.
How is swing music written?
Swing Rhythm
While the sheet music is written in the same way as a straight rhythm, the way you play it is very different. A swung rhythm has a triplet feel, but skips the middle triplet.
