The beat the song is built on is one bar, played through bars 6-8, 10-12 and 14-16, and 13 more places -- 49.1% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 36 out of 100 -- a fair first song -- and the thing that decides that is how many notes a second it asks for.
The whole song is 67 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 103 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 103, 120 and 137 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 137 BPM, counted in sixteenth notes. It is written out above, and it covers 49.1% of the bars the kit plays.
Bars 6-8, 10-12, 14-16 and 18-20, and 12 more places. The time is kept on the silence to start with, and it changes 13 times over the song.
36 out of 100 on its own -- a fair first song. The song as a whole is 67 out of 100: demanding, mostly on the independence between the hands and the feet.
