The beat the song is built on is a 2-bar phrase, played through bars 57-59, 61-63 and 65-67, and 9 more places -- 16.3% 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, mid tom, floor tom and kick, counted in thirty-second notes. On its own it scores 51 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 87 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 137 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 137, 161, 186 and 210 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, mid tom, floor tom and kick, in 4/4 at 210 BPM, counted in thirty-second notes. It is written out above, and it covers 16.3% of the bars the kit plays.
Bars 57-59, 61-63, 65-67 and 69-71, and 8 more places. The time is kept on the hi-hat to start with, and it changes 31 times over the song.
51 out of 100 on its own -- a step up. The song as a whole is 87 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
