Placing two hi-hats per beat from a quintuplet grid produces a 3:2 ratio — quintuplet swing

In a standard 8th-note hi-hat pattern, two hits per beat are spaced in a 1:1 ratio. When you instead pick two positions from a 5-note (quintuplet) grid per beat — the first on the downbeat and the second on the 4th quintuplet position — the gap between them is 3 units while the remaining gap to the next beat is 2 units: a 3:2 ratio. This is quintuplet swing. Septuplet swing (using 7-note divisions) produces a 4:3 ratio. Neither feels like simple straight or triplet timing; they create a characteristic lopsided-but-precise bounce. This is distinct from MPC-style percentage swing, which moves the 2nd 16th note toward the 3rd.

Examples

Program a hi-hat with the first hit on the quarter note and the second hit on the 4th quintuplet position. The ratio of the gap before and after the second hit will be 3:2. Compare to a triplet-based swing.

Assessment

What is the beat-gap ratio produced by placing two hits per beat from a quintuplet grid? How does septuplet swing differ numerically, and how would you hear the difference?
