The beat the song is built on is one bar, played through bars 5-11, 13-19 and 21-27, and 2 more places -- 18.5% 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 58 out of 100 -- a step up -- and the thing that decides that is how much of it falls off the beat.
The whole song is 83 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 99 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 99, 117, 134 and 152 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 152 BPM, counted in thirty-second notes. It is written out above, and it covers 18.5% of the bars the kit plays.
Bars 5-11, 13-19, 21-27 and 93-99, and 1 more place. The time is kept on the kick and crashes to start with, and it changes 5 times over the song.
58 out of 100 on its own -- a step up. The song as a whole is 83 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
