The beat the song is built on is a 2-bar phrase, played through bars 30-35, 38-43 and 86-91, and 4 more places -- 16.5% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 73 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 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 120 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 120, 144, 169, 193 and 218 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 2-bar phrase on crash, hi-hat, snare and kick, in 4/4 at 218 BPM, counted in sixteenth notes. It is written out above, and it covers 16.5% of the bars the kit plays.
Bars 30-35, 38-43, 86-91 and 94-99, and 3 more places. The time is kept on the kick and crashes to start with, and it changes 34 times over the song.
73 out of 100 on its own -- demanding. The song as a whole is 82 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
