The beat the song is built on is one bar, played through bars 10-12, 14-16 and 18-20, and 26 more places -- 26.3% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash and kick, counted in sixteenth notes. On its own it scores 16 out of 100 -- straightforward -- and the thing that decides that is how many notes a second it asks for.
The whole song is 36 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 165 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 165, 193 and 220 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 and kick, in 4/4 at 220 BPM, counted in sixteenth notes. It is written out above, and it covers 26.3% of the bars the kit plays.
Bars 10-12, 14-16, 18-20 and 22-23, and 25 more places. The time is kept on the kick and crashes to start with, and it changes 8 times over the song.
16 out of 100 on its own -- straightforward. The song as a whole is 36 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
