The beat the song is built on is one bar, played through bars 14, 16 and 18, and 11 more places -- 15% 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 63 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 66 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 62 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 62, 73, 84 and 95 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 95 BPM, counted in thirty-second notes. It is written out above, and it covers 15% of the bars the kit plays.
Bars 14, 16, 18 and 20, and 10 more places. The time is kept on the silence to start with, and it changes 16 times over the song.
63 out of 100 on its own -- a step up. The song as a whole is 66 out of 100: demanding, mostly on the independence between the hands and the feet.
