The beat the song is built on is one bar, played through bars 45, 47 and 49, and 18 more places -- 16.2% 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 33 out of 100 -- a fair first song -- 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 162 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 162, 189 and 216 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 216 BPM, counted in thirty-second notes. It is written out above, and it covers 16.2% of the bars the kit plays.
Bars 45, 47, 49 and 53-55, and 17 more places. The time is kept on the silence to start with, and it changes 26 times over the song.
33 out of 100 on its own -- a fair first song. The song as a whole is 66 out of 100: demanding, mostly on the independence between the hands and the feet.
