The beat the song is built on is one bar, played through bars 2-9, 26-31 and 50-54, and 1 more place -- 31.7% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on the kick, counted in sixteenth notes. On its own it scores 0 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 62 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 101 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 101, 118 and 135 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 kick, in 4/4 at 135 BPM, counted in sixteenth notes. It is written out above, and it covers 31.7% of the bars the kit plays.
Bars 2-9, 26-31, 50-54 and 72-85. The time is kept on the snare to start with, and it changes 12 times over the song.
0 out of 100 on its own -- straightforward. The song as a whole is 62 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
