The beat the song is built on is one bar, played through bars 22-24, 26-31 and 35-49, and 3 more places -- 58.6% 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 78 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 82 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 127 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 127, 152, 178, 204 and 230 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 230 BPM, counted in sixteenth notes. It is written out above, and it covers 58.6% of the bars the kit plays.
Bars 22-24, 26-31, 35-49 and 63-73, and 2 more places. The time is kept on the kick and crashes to start with, and it changes 6 times over the song.
78 out of 100 on its own -- demanding. The song as a whole is 82 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
