The beat the song is built on is one bar, played through bars 9-13, 17-31 and 57-61, and 1 more place -- 28.4% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 50 out of 100 -- a step up -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 55 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 117 BPM, and adds the notes back a rung at a time -- 4 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 117, 138, 159 and 180 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, ride, hi-hat, snare and kick, in 4/4 at 180 BPM, counted in sixteenth notes. It is written out above, and it covers 28.4% of the bars the kit plays.
Bars 9-13, 17-31, 57-61 and 65-79. The time is kept on the silence to start with, and it changes 14 times over the song.
50 out of 100 on its own -- a step up. The song as a whole is 55 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
