The beat the song is built on is a 2-bar phrase, played through bars 2-13, 22-29 and 38-39, and 2 more places -- 24% 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 9 out of 100 -- straightforward -- and the thing that decides that is how often it moves around the kit.
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 108 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 108, 126 and 144 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 144 BPM, counted in sixteenth notes. It is written out above, and it covers 24% of the bars the kit plays.
Bars 2-13, 22-29, 38-39 and 76-77, and 1 more place. The time is kept on the snare to start with, and it changes 1 time over the song.
9 out of 100 on its own -- straightforward. 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.
