The beat the song is built on is one bar, played through bars 69-83, 114-129 and 132-133 -- 20.5% 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 ride, snare and kick, counted in thirty-second notes. On its own it scores 69 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 75 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 114 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 114, 135, 155 and 176 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 ride, snare and kick, in 4/4 at 176 BPM, counted in thirty-second notes. It is written out above, and it covers 20.5% of the bars the kit plays.
Bars 69-83, 114-129 and 132-133. The time is kept on the silence to start with, and it changes 10 times over the song.
69 out of 100 on its own -- demanding. The song as a whole is 75 out of 100: demanding, mostly on the independence between the hands and the feet.
