The beat the song is built on is one bar, played through bars 141-152, 154-156 and 158, and 9 more places -- 19.8% 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, snare and kick, counted in thirty-second notes. On its own it scores 16 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
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 53 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 53, 61 and 70 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, snare and kick, in 4/4 at 70 BPM, counted in thirty-second notes. It is written out above, and it covers 19.8% of the bars the kit plays.
Bars 141-152, 154-156, 158 and 160-162, and 8 more places. The time is kept on the hi-hat to start with, and it changes 11 times over the song.
16 out of 100 on its own -- straightforward. The song as a whole is 80 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
