The beat the song is built on is one bar, played through bars 10-25, 36-42 and 44-51, and 10 more places -- 31.1% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in thirty-second 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 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 118 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 118, 142, 166, 190 and 214 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 214 BPM, counted in thirty-second notes. It is written out above, and it covers 31.1% of the bars the kit plays.
Bars 10-25, 36-42, 44-51 and 84-85, and 9 more places. The time is kept on the kick and crashes to start with, and it changes 2 times over the song.
82 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.
