The drum beat in Natural Born Killer AI

The beat the song is built on is a 2-bar phrase, played through bars 34-40, 70-76 and 78-84 -- 21.9% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

It is played on crash, snare and kick, counted in sixteenth notes. On its own it scores 54 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.

The whole song is 51 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.

The room opens this beat on its simplest reduction, at 104 BPM, and adds the notes back a rung at a time -- 4 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.

1. Skeleton. Only the notes that land on a beat. The point is to feel where this bar stands.
2. Kick and snare, whole. The feet and the snare exactly as written, and nothing else. This is the part to know by heart.
3. As written. Open hi-hat, ghost notes, accents and the crash where they belong.

Tempo goes 104, 123, 141 and 160 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
