The beat the song is built on is one bar, played through bars 15-17, 33-35 and 37-39, and 4 more places -- 21.5% 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 60 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 70 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 104 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 104, 123, 141 and 160 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 160 BPM, counted in thirty-second notes. It is written out above, and it covers 21.5% of the bars the kit plays.
Bars 15-17, 33-35, 37-39 and 83-85, and 3 more places. The time is kept on the snare to start with, and it changes 14 times over the song.
60 out of 100 on its own -- a step up. The song as a whole is 70 out of 100: demanding, mostly on how many notes a second it asks for.
