The beat the song is built on is a 2-bar phrase, played through bars 8-11 and 27-37 -- 22.7% 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, ride, hi-hat, snare, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 40 out of 100 -- a fair first song -- and the thing that decides that is how much of it falls off the beat.
The whole song is 41 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 90 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 90, 105 and 120 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
