The beat the song is built on is one bar, played through bars 1-10 and 74-81 -- 15.3% 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 and kick, counted in sixteenth notes. On its own it scores 20 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
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 122 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 122, 143 and 163 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 and kick, in 4/4 at 163 BPM, counted in sixteenth notes. It is written out above, and it covers 15.3% of the bars the kit plays.
Bars 1-10 and 74-81. The time is kept on the hi-hat to start with, and it changes 11 times over the song.
20 out of 100 on its own -- straightforward. The song as a whole is 69 out of 100: demanding, mostly on the independence between the hands and the feet.
