The beat the song is built on is one bar, played through bars 17-23, 25-28 and 31-36, and 13 more places -- 50.4% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 71 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 84 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 76 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 76, 92, 108, 123 and 139 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 hi-hat, snare and kick, in 4/4 at 139 BPM, counted in sixteenth notes. It is written out above, and it covers 50.4% of the bars the kit plays.
Bars 17-23, 25-28, 31-36 and 39-41, and 12 more places. The time is kept on the toms to start with, and it changes 4 times over the song.
71 out of 100 on its own -- demanding. The song as a whole is 84 out of 100. Hard, and what makes it hard is the speed of the hand keeping time.
