The beat the song is built on is a 2-bar phrase, played through bars 10-15, 18-23 and 107-112, and 1 more place -- 18.5% 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 52 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 79 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 133 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 133, 157, 181 and 205 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 6/4 at 205 BPM, counted in sixteenth notes. It is written out above, and it covers 18.5% of the bars the kit plays.
Bars 10-15, 18-23, 107-112 and 115-118. The time is kept on the toms to start with, and it changes 11 times over the song.
52 out of 100 on its own -- a step up. The song as a whole is 79 out of 100: demanding, mostly on the independence between the hands and the feet.
