The beat the song is built on is one bar, played through bars 23-25, 27-29 and 44-45, and 3 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 hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 63 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 91 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 91, 107, 124 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 hi-hat, snare and kick, in 4/4 at 140 BPM, counted in thirty-second notes. It is written out above, and it covers 16.3% of the bars the kit plays.
Bars 23-25, 27-29, 44-45 and 48, and 2 more places. The time is kept on the kick and crashes to start with, and it changes 16 times over the song.
63 out of 100 on its own -- a step up. The song as a whole is 72 out of 100: demanding, mostly on how much of it falls off the beat.
