The beat the song is built on is one bar, played through bars 87-115, 200-258 and 260 -- 26.2% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on snare and kick, counted in thirty-second notes. On its own it scores 44 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 64 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 109 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 109, 127 and 145 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 snare and kick, in 3/4 at 145 BPM, counted in thirty-second notes. It is written out above, and it covers 26.2% of the bars the kit plays.
Bars 87-115, 200-258 and 260. The time is kept on the toms to start with, and it changes 18 times over the song.
44 out of 100 on its own -- a fair first song. The song as a whole is 64 out of 100, a step up from a first song, and the work is in how much of it falls off the beat.
