The beat the song is built on is one bar, played through bars 6-9, 14-16 and 22-24, and 5 more places -- 20.2% 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 hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 16 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 78 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 101 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 101, 118 and 135 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 135 BPM, counted in sixteenth notes. It is written out above, and it covers 20.2% of the bars the kit plays.
Bars 6-9, 14-16, 22-24 and 30-32, and 4 more places. The time is kept on the silence to start with, and it changes 17 times over the song.
16 out of 100 on its own -- straightforward. The song as a whole is 78 out of 100: demanding, mostly on the independence between the hands and the feet.
