The beat the song is built on is one bar, played through bars 25-31, 57-58 and 93-97, and 6 more places -- 15.7% 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, hi-hat, 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 how fine the subdivision is.
The whole song is 73 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 125 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 125, 145 and 166 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, hi-hat, snare and kick, in 4/4 at 166 BPM, counted in thirty-second notes. It is written out above, and it covers 15.7% of the bars the kit plays.
Bars 25-31, 57-58, 93-97 and 103, and 5 more places. The time is kept on the silence to start with, and it changes 12 times over the song.
33 out of 100 on its own -- a fair first song. The song as a whole is 73 out of 100: demanding, mostly on the independence between the hands and the feet.
