The beat the song is built on is one bar, played through bars 6-7, 10-11 and 30-31, and 7 more places -- 15.2% 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 ride, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 54 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 69 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 112 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 112, 133, 153 and 173 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 ride, snare, kick and hi-hat foot, in 4/4 at 173 BPM, counted in sixteenth notes. It is written out above, and it covers 15.2% of the bars the kit plays.
Bars 6-7, 10-11, 30-31 and 34-35, and 6 more places. The time is kept on the hi-hat to start with, and it changes 11 times over the song.
54 out of 100 on its own -- a step up. The song as a whole is 69 out of 100: demanding, mostly on the independence between the hands and the feet.
