The beat the song is built on is one bar, played through bars 14-15, 18-19 and 34-35, and 7 more places -- 26% 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, snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 43 out of 100 -- a fair first song -- and the thing that decides that is how many notes a second it asks for.
The whole song is 68 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 80 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 80, 93 and 106 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, snare, kick and hi-hat foot, in 4/4 at 106 BPM, counted in sixteenth notes. It is written out above, and it covers 26% of the bars the kit plays.
Bars 14-15, 18-19, 34-35 and 38-39, and 6 more places. The time is kept on the snare to start with, and it changes 6 times over the song.
43 out of 100 on its own -- a fair first song. The song as a whole is 68 out of 100: demanding, mostly on the independence between the hands and the feet.
