The beat the song is built on is a 2-bar phrase, played through bars 7-13, 39-47 and 55-61, and 4 more places -- 20.1% 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 crash, ride, snare, kick and hi-hat foot, counted in thirty-second notes. On its own it scores 34 out of 100 -- a fair first song -- and the thing that decides that is how fine the subdivision is.
The whole song is 81 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 48 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 48, 56 and 64 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 2-bar phrase on crash, ride, snare, kick and hi-hat foot, in 3/4 at 64 BPM, counted in thirty-second notes. It is written out above, and it covers 20.1% of the bars the kit plays.
Bars 7-13, 39-47, 55-61 and 87-89, and 3 more places. The time is kept on the silence to start with, and it changes 16 times over the song.
34 out of 100 on its own -- a fair first song. The song as a whole is 81 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
