The beat the song is built on is one bar, played through bars 9-10, 13 and 41-42, and 21 more places -- 24.3% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on hi-hat, snare and kick, counted in thirty-second notes. On its own it scores 82 out of 100 -- hard -- and the thing that decides that is how many notes a second it asks for.
The whole song is 98 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 124 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 124, 149, 174, 200 and 225 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 225 BPM, counted in thirty-second notes. It is written out above, and it covers 24.3% of the bars the kit plays.
Bars 9-10, 13, 41-42 and 69-71, and 20 more places. The time is kept on the hi-hat to start with, and it changes 13 times over the song.
82 out of 100 on its own -- hard. The song as a whole is 98 out of 100. Hard, and what makes it hard is how many notes a second it asks for.
