The beat the song is built on is one bar, played through bars 73-87, 125-139 and 141-155, and 5 more places -- 33% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on snare, high 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 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 155 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 155, 180 and 206 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 snare, high tom, floor tom and kick, in 4/4 at 206 BPM, counted in sixteenth notes. It is written out above, and it covers 33% of the bars the kit plays.
Bars 73-87, 125-139, 141-155 and 181-195, and 4 more places. The time is kept on the hi-hat to start with, and it changes 11 times over the song.
40 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.
