The beat the song is built on is one bar, played through bars 45-47, 53 and 118, and 37 more places -- 19.7% 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 and kick, counted in thirty-second notes. On its own it scores 47 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 72 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 105 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 105, 123 and 140 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 and kick, in 3/4 at 140 BPM, counted in thirty-second notes. It is written out above, and it covers 19.7% of the bars the kit plays.
Bars 45-47, 53, 118 and 125-126, and 36 more places. The time is kept on the silence to start with, and it changes 64 times over the song.
47 out of 100 on its own -- a step up. The song as a whole is 72 out of 100: demanding, mostly on the independence between the hands and the feet.
