The beat the song is built on is one bar, played through bars 40-46, 48 and 50-54, and 24 more places -- 38.7% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash and kick, counted in thirty-second notes. On its own it scores 7 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 73 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 109 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 109, 127 and 145 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 crash and kick, in 4/4 at 145 BPM, counted in thirty-second notes. It is written out above, and it covers 38.7% of the bars the kit plays.
Bars 40-46, 48, 50-54 and 56, and 23 more places. The time is kept on the hi-hat to start with, and it changes 6 times over the song.
7 out of 100 on its own -- straightforward. The song as a whole is 73 out of 100: demanding, mostly on the independence between the hands and the feet.
