The beat the song is built on is one bar, played through bars 1-3, 5-7 and 17-19, and 17 more places -- 39.4% 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 68 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 82 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 75 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 75, 89, 102 and 116 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 116 BPM, counted in thirty-second notes. It is written out above, and it covers 39.4% of the bars the kit plays.
Bars 1-3, 5-7, 17-19 and 21, and 16 more places. The time is kept on the hi-hat to start with, and it changes 1 time over the song.
68 out of 100 on its own -- demanding. The song as a whole is 82 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
