The beat the song is built on is one bar, played through bars 23-24, 42-43 and 46-48, and 6 more places -- 27.2% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, 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 the independence between the hands and the feet.
The whole song is 94 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 73 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 73, 87, 102, 117 and 132 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 crash, ride, hi-hat, snare and kick, in 4/4 at 132 BPM, counted in thirty-second notes. It is written out above, and it covers 27.2% of the bars the kit plays.
Bars 23-24, 42-43, 46-48 and 50-56, and 5 more places. The time is kept on the silence to start with, and it changes 1 time over the song.
82 out of 100 on its own -- hard. The song as a whole is 94 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
