The beat the song is built on is one bar, played through bars 1-24, 29-32 and 43-46, and 2 more places -- 54.9% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 19 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 105 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 105, 123 and 140 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 140 BPM, counted in thirty-second notes. It is written out above, and it covers 54.9% of the bars the kit plays.
Bars 1-24, 29-32, 43-46 and 51-65, and 1 more place. The time is kept on the hi-hat to start with, and it changes 12 times over the song.
19 out of 100 on its own -- straightforward. The song as a whole is 80 out of 100. Hard, and what makes it hard is how much of it falls off the beat.
