Part 4 · Rock Grooves · Chapter 57
At faster tempos, play the hi-hat sixteenths with both hands: R L R L. On beats 2 and 4, the right hand moves to the snare while the left keeps going on the hi-hat.
The right hand leaves the hi-hat to play the backbeat.
This technique is behind many disco and funk grooves. Keep the left hand soft and steady; it is the engine.
