The beat the song is built on is one bar, played through bars 7-9, 11-16 and 18-20, and 9 more places -- 31.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 42 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 57 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 82 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 82, 95 and 109 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 109 BPM, counted in sixteenth notes. It is written out above, and it covers 31.3% of the bars the kit plays.
Bars 7-9, 11-16, 18-20 and 22-23, and 8 more places. The time is kept on the snare to start with, and it changes 9 times over the song.
42 out of 100 on its own -- a fair first song. The song as a whole is 57 out of 100, a step up from a first song, and the work is in how often it moves around the kit.
