The beat the song is built on is one bar, played through bars 33-48, 73-75 and 77-79, and 3 more places -- 48.4% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 80 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 87 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 94 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 94, 113, 132, 151 and 170 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 crash, hi-hat, snare and kick, in 4/4 at 170 BPM, counted in sixteenth notes. It is written out above, and it covers 48.4% of the bars the kit plays.
Bars 33-48, 73-75, 77-79 and 81-83, and 2 more places. The time is kept on the kick and crashes to start with, and it changes 5 times over the song.
80 out of 100 on its own -- hard. The song as a whole is 87 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
