The beat the song is built on is one bar, played through bars 17-23, 66-72 and 74-79, and 2 more places -- 23.9% 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 and kick, counted in thirty-second notes. On its own it scores 80 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 90 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 74 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 74, 89, 105, 120 and 135 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 and kick, in 4/4 at 135 BPM, counted in thirty-second notes. It is written out above, and it covers 23.9% of the bars the kit plays.
Bars 17-23, 66-72, 74-79 and 123-129, and 1 more place. The time is kept on the silence to start with, and it changes 23 times over the song.
80 out of 100 on its own -- hard. The song as a whole is 90 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
