The beat the song is built on is one bar, played through bars 21-27, 62-69 and 91-95 -- 19% 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, snare and kick, counted in thirty-second notes. On its own it scores 68 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 86 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 72 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 72, 84, 97 and 110 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, snare and kick, in 4/4 at 110 BPM, counted in thirty-second notes. It is written out above, and it covers 19% of the bars the kit plays.
Bars 21-27, 62-69 and 91-95. The time is kept on the toms to start with, and it changes 8 times over the song.
68 out of 100 on its own -- demanding. The song as a whole is 86 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
