The beat the song is built on is one bar, played through bars 9, 11-13 and 15-17, and 8 more places -- 23.1% 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 thirty-second notes. On its own it scores 26 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
The whole song is 65 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 98 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 98, 114 and 130 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 130 BPM, counted in thirty-second notes. It is written out above, and it covers 23.1% of the bars the kit plays.
Bars 9, 11-13, 15-17 and 19-21, and 7 more places. The time is kept on the kick and crashes to start with, and it changes 9 times over the song.
26 out of 100 on its own -- a fair first song. The song as a whole is 65 out of 100: demanding, mostly on the independence between the hands and the feet.
