The beat the song is built on is one bar, played through bars 5, 7 and 9, and 37 more places -- 30.6% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 22 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 54 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 75 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 75, 88 and 100 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, snare and kick, in 4/4 at 100 BPM, counted in thirty-second notes. It is written out above, and it covers 30.6% of the bars the kit plays.
Bars 5, 7, 9 and 11, and 36 more places. The time is kept on the silence to start with, and it changes 34 times over the song.
22 out of 100 on its own -- straightforward. The song as a whole is 54 out of 100, a step up from a first song, and the work is in the independence between the hands and the feet.
