The beat the song is built on is a 2-bar phrase, played through bars 50-65, 96-111 and 171-173, and 8 more places -- 20.8% 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, snare, high tom, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 58 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 80 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 109 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 109, 129, 148 and 168 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 2-bar phrase on crash, ride, snare, high tom, mid tom, floor tom and kick, in 3/4 at 168 BPM, counted in sixteenth notes. It is written out above, and it covers 20.8% of the bars the kit plays.
Bars 50-65, 96-111, 171-173 and 175-177, and 7 more places. The time is kept on the toms to start with, and it changes 15 times over the song.
58 out of 100 on its own -- a step up. The song as a whole is 80 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
