The beat the song is built on is one bar, played through bars 4, 10 and 12, and 13 more places -- 43.5% 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 100 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 100 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 61 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 61, 73, 85, 98 and 110 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 110 BPM, counted in thirty-second notes. It is written out above, and it covers 43.5% of the bars the kit plays.
Bars 4, 10, 12 and 16, and 12 more places. The time is kept on the silence to start with, and it changes 8 times over the song.
100 out of 100 on its own -- hard. The song as a whole is 100 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
