The beat the song is built on is one bar, played through bars 18-33, 42-57 and 127-142, and 1 more place -- 35.6% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 73 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 92 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 124 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 124, 149, 174, 200 and 225 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 225 BPM, counted in sixteenth notes. It is written out above, and it covers 35.6% of the bars the kit plays.
Bars 18-33, 42-57, 127-142 and 151-166. The time is kept on the snare to start with, and it changes 19 times over the song.
73 out of 100 on its own -- demanding. The song as a whole is 92 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
