The beat the song is built on is one bar, played through bars 7, 10 and 12, and 21 more places -- 15.8% 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 snare, floor tom and kick, counted in sixteenth notes. On its own it scores 53 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 66 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 88 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 88, 104, 119 and 135 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 snare, floor tom and kick, in 4/4 at 135 BPM, counted in sixteenth notes. It is written out above, and it covers 15.8% of the bars the kit plays.
Bars 7, 10, 12 and 15-17, and 20 more places. The time is kept on the silence to start with, and it changes 7 times over the song.
53 out of 100 on its own -- a step up. The song as a whole is 66 out of 100: demanding, mostly on the independence between the hands and the feet.
