The beat the song is built on is a 2-bar phrase, played through bars 1-8, 13-16 and 26-29, and 2 more places -- 70.8% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on the hi-hat, counted in thirty-second notes. On its own it scores 35 out of 100 -- a fair first song -- and the thing that decides that is how much of it falls off the beat.
The whole song is 59 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
The room opens this beat on its simplest reduction, at 79 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 79, 92 and 105 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
