The drum beat in AtopaHil

The beat the song is built on is one bar, played through bars 1, 3 and 7, and 10 more places -- 23.8% 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, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 65 out of 100 -- demanding -- and the thing that decides that is the independence between the hands and the feet.

The whole song is 68 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.

A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 117 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.

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, hi-hat pulled back to quarter notes. This is the part to know by heart.
3. Every note, flat. All the notes, but the hi-hat stays closed and nothing is ghosted or accented.
4. As written. Open hi-hat, ghost notes, accents and the crash where they belong.

Tempo goes 117, 138, 159 and 180 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
