One move, a beat later
This is the groove as written, rotated by one beat.
Rotation slides the whole bar along in time and wraps the front around to the back — so the loop begins one beat in:
as written snare . . . . x . . . . . . . x . . . (backbeat: 2 and 4)
rotated snare x . . . . . . . x . . . . . . . (now on 1 and 3)The snare that fell on the backbeat now lands on the downbeats, while the steady hat pulse — even under the shift — holds exactly where it was. The feel changes completely, and not a hit was added or removed.
It’s the same move you’d use to start a phrase later in the bar. Here it’s pointed at a beat, so the groove itself turns.
