The beat the song is built on is one bar, played through bars 11-15, 33-47 and 49-56, and 1 more place -- 42.4% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash and kick, counted in thirty-second notes. On its own it scores 20 out of 100 -- straightforward -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 67 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 and kick, in 4/4 at 140 BPM, counted in thirty-second notes. It is written out above, and it covers 42.4% of the bars the kit plays.
Bars 11-15, 33-47, 49-56 and 65-72. The time is kept on the snare to start with, and it changes 4 times over the song.
20 out of 100 on its own -- straightforward. The song as a whole is 67 out of 100: demanding, mostly on how much of it falls off the beat.
