The beat the song is built on is one bar, played through bars 3-4, 10-20 and 22-25, and 2 more places -- 47.1% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, high tom and floor tom, counted in thirty-second notes. On its own it scores 24 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 32 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 60 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 60, 70 and 80 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
