The beat the song is built on is one bar, played through bars 9-15, 31-35 and 37-39, and 6 more places -- 18.2% 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 and kick, counted in sixteenth notes. On its own it scores 52 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 65 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 85 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 85, 100, 115 and 130 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, hi-hat, snare and kick, in 4/4 at 130 BPM, counted in sixteenth notes. It is written out above, and it covers 18.2% of the bars the kit plays.
Bars 9-15, 31-35, 37-39 and 46-50, and 5 more places. The time is kept on the toms to start with, and it changes 12 times over the song.
52 out of 100 on its own -- a step up. The song as a whole is 65 out of 100: demanding, mostly on the independence between the hands and the feet.
