The beat the song is built on is one bar, played through bars 18-20, 22-24 and 67-69, and 7 more places -- 16% 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 hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 75 out of 100 -- demanding -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 82 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 99 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 99, 119, 140, 160 and 180 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 hi-hat, snare and kick, in 4/4 at 180 BPM, counted in thirty-second notes. It is written out above, and it covers 16% of the bars the kit plays.
Bars 18-20, 22-24, 67-69 and 71-73, and 6 more places. The time is kept on the hi-hat to start with, and it changes 5 times over the song.
75 out of 100 on its own -- demanding. The song as a whole is 82 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
