The beat the song is built on is one bar, played through bars 10-12, 26-28 and 30-32, and 3 more places -- 25.7% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, ride, snare and kick, counted in sixteenth notes. On its own it scores 13 out of 100 -- straightforward -- and the thing that decides that is how often it moves around the kit.
The whole song is 41 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 59 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 59, 68 and 78 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, ride, snare and kick, in 4/4 at 78 BPM, counted in sixteenth notes. It is written out above, and it covers 25.7% of the bars the kit plays.
Bars 10-12, 26-28, 30-32 and 34-36, and 2 more places. The time is kept on the silence to start with, and it changes 11 times over the song.
13 out of 100 on its own -- straightforward. The song as a whole is 41 out of 100 -- a fair first song -- with the independence between the hands and the feet the part that decides it.
