The beat the song is built on is one bar, played through bars 1-16, 43-49 and 83, and 4 more places -- 29.8% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on snare, high tom, floor tom, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 57 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 89 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 107 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 107, 127, 146 and 165 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 snare, high tom, floor tom, kick and hi-hat foot, in 4/4 at 165 BPM, counted in sixteenth notes. It is written out above, and it covers 29.8% of the bars the kit plays.
Bars 1-16, 43-49, 83 and 85, and 3 more places. The time is kept on the toms to start with, and it changes 6 times over the song.
57 out of 100 on its own -- a step up. The song as a whole is 89 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
