The beat the song is built on is one bar, played through bars 2-12, 14-17 and 19-32, and 4 more places -- 33.9% 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 52 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 61 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 89 BPM, and adds the notes back a rung at a time -- 4 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 89, 105, 121 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 33.9% of the bars the kit plays.
Bars 2-12, 14-17, 19-32 and 59-65, and 3 more places. The time is kept on the snare to start with, and it changes 10 times over the song.
52 out of 100 on its own -- a step up. The song as a whole is 61 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
