The beat the song is built on is one bar, played through bars 33-52 and 166-185 -- 17.4% 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, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 9 out of 100 -- straightforward -- and the thing that decides that is how many limbs land on the same note.
The whole song is 65 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, mid tom, floor tom and kick, in 4/4 at 140 BPM, counted in sixteenth notes. It is written out above, and it covers 17.4% of the bars the kit plays.
Bars 33-52 and 166-185. The time is kept on the snare to start with, and it changes 19 times over the song.
9 out of 100 on its own -- straightforward. The song as a whole is 65 out of 100: demanding, mostly on the independence between the hands and the feet.
