AXIS
Six positions. Neighbours are semitones at one stop and fifths at the opposite. The notes stay; what “next to” means changes.
Harmony is a cycle of twelve, not a line. Axis Gemina puts that cycle in space so you can play its symmetries.
Harmony is usually written as a line: a keyboard, a staff, a piano roll. The twelve notes are a cycle. Intervals, chords and scales are symmetries of that cycle. Axis Gemina puts the cycle in space so you can play those symmetries directly — an interval is a distance, a chord is a shape, a scale is a path, transposition is a rotation.
What you actually touch. Nothing else.

The scale paints which seats belong. LOCK: out-of-scale notes do not sound. The map does not redraw.
A route on the same figure — play, rate, cycle. Not a piano roll beside the instrument.
The rim deals the chords of the key. Attack is BLOCK or ARP.
How the twelve are seated. The photo is Sacred — Flower.
An external keyboard lights the same seats you play with your hands.
