The beat the song is built on is one bar, played through bars 6-10, 21-25 and 31-32, and 4 more places -- 16.5% 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 sixteenth notes. On its own it scores 60 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 69 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 81 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 81, 96, 110 and 125 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 125 BPM, counted in sixteenth notes. It is written out above, and it covers 16.5% of the bars the kit plays.
Bars 6-10, 21-25, 31-32 and 34-35, and 3 more places. The time is kept on the toms to start with, and it changes 6 times over the song.
60 out of 100 on its own -- a step up. The song as a whole is 69 out of 100: demanding, mostly on the independence between the hands and the feet.
