The beat the song is built on is one bar, played through bars 1-7, 13-19 and 21-27, and 2 more places -- 29.7% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 82 out of 100 -- hard -- 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 97 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 97, 117, 137, 157 and 177 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 177 BPM, counted in sixteenth notes. It is written out above, and it covers 29.7% of the bars the kit plays.
Bars 1-7, 13-19, 21-27 and 37-43, and 1 more place. The time is kept on the hi-hat to start with, and it changes 6 times over the song.
82 out of 100 on its own -- hard. 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.
