The beat the song is built on is one bar, played through bars 1, 3 and 5, and 26 more places -- 38.1% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, snare and kick, counted in thirty-second notes. On its own it scores 94 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 97 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
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 96 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 96, 116, 136, 155 and 175 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 ride, snare and kick, in 4/4 at 175 BPM, counted in thirty-second notes. It is written out above, and it covers 38.1% of the bars the kit plays.
Bars 1, 3, 5 and 9, and 25 more places. The time is kept on the ride to start with, and it changes 10 times over the song.
94 out of 100 on its own -- hard. The song as a whole is 97 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
