The beat the song is built on is one bar, played through bars 34-44 and 54-65 -- 35.9% 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 thirty-second notes. On its own it scores 83 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 99 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 69 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 69, 83, 98, 112 and 126 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 126 BPM, counted in thirty-second notes. It is written out above, and it covers 35.9% of the bars the kit plays.
Bars 34-44 and 54-65. The time is kept on the kick and crashes to start with, and it changes 8 times over the song.
83 out of 100 on its own -- hard. The song as a whole is 99 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
