One move, on the whole beat
This is the groove as written, reversed.
The beat is a grid — one row per drum, one column per sixteenth — so reversing it in time turns every row back to front at the same instant:
as written kick x . . . . . . x . . x . . . . .
snare . . . . x . . . . . . . x . . .
reversed kick . . . . . x . . x . . . . . . x
snare . . . x . . . . . . . x . . . .
Flip the grid and the snare leaves the backbeat — it now answers on the offbeats — while the kick that opened the bar lands at the very end. Same three drums, same number of hits, nothing rebuilt; only their order in time moved.
It’s the exact move you’d use to play a melody back to front. The difference is the material: the “notes” being reversed are the hits of a drum beat, so what flips is the groove.
