The beat the song is built on is one bar, played through bars 1, 3 and 5, and 10 more places -- 25% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 16 out of 100 -- straightforward -- and the thing that decides that is how often it moves around the kit.
The whole song is 52 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 105 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 105, 123 and 140 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, hi-hat, snare and kick, in 4/4 at 140 BPM, counted in sixteenth notes. It is written out above, and it covers 25% of the bars the kit plays.
Bars 1, 3, 5 and 7, and 9 more places. The time is kept on the hi-hat 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 52 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
