The beat the song is built on is one bar, played through bars 1, 3 and 5, and 60 more places -- 45.3% 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 55 out of 100 -- a step up -- and the thing that decides that is the speed of the hand keeping time.
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 73 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 73, 87, 100 and 113 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 113 BPM, counted in sixteenth notes. It is written out above, and it covers 45.3% of the bars the kit plays.
Bars 1, 3, 5 and 7, and 59 more places. The time is kept on the hi-hat to start with, and it changes 4 times over the song.
55 out of 100 on its own -- a step up. The song as a whole is 67 out of 100: demanding, mostly on how many notes a second it asks for.
