The beat the song is built on is one bar, played through bars 19, 21 and 23, and 23 more places -- 34.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on ride, snare and kick, counted in thirty-second notes. On its own it scores 88 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 98 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 71 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 71, 85, 100, 114 and 129 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 ride, snare and kick, in 4/4 at 129 BPM, counted in thirty-second notes. It is written out above, and it covers 34.3% of the bars the kit plays.
Bars 19, 21, 23 and 25, and 22 more places. The time is kept on the toms to start with, and it changes 16 times over the song.
88 out of 100 on its own -- hard. The song as a whole is 98 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
