The beat the song is built on is one bar, played through bars 6, 8 and 10, and 7 more places -- 18% 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 crash, snare and kick, counted in thirty-second notes. On its own it scores 53 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 77 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 78 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 78, 92, 106 and 120 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, snare and kick, in 4/4 at 120 BPM, counted in thirty-second notes. It is written out above, and it covers 18% of the bars the kit plays.
Bars 6, 8, 10 and 12, and 6 more places. The time is kept on the snare to start with, and it changes 13 times over the song.
53 out of 100 on its own -- a step up. The song as a whole is 77 out of 100: demanding, mostly on the independence between the hands and the feet.
