The beat the song is built on is one bar, played through bars 23-34, 39-50 and 71-80, and 2 more places -- 41.2% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 43 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 86 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 90 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 90, 105 and 120 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 120 BPM, counted in thirty-second notes. It is written out above, and it covers 41.2% of the bars the kit plays.
Bars 23-34, 39-50, 71-80 and 82, and 1 more place. The time is kept on the hi-hat to start with, and it changes 9 times over the song.
43 out of 100 on its own -- a fair first song. The song as a whole is 86 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
