The beat the song is built on is one bar, played through bars 11-34, 41-46 and 53-58, and 14 more places -- 44.4% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 78 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 91 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 105 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 105, 126, 147, 169 and 190 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on ride, snare and kick, in 3/4 at 190 BPM, counted in sixteenth notes. It is written out above, and it covers 44.4% of the bars the kit plays.
Bars 11-34, 41-46, 53-58 and 71-79, and 13 more places. The time is kept on the hi-hat to start with, and it changes 43 times over the song.
78 out of 100 on its own -- demanding. The song as a whole is 91 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
