A Ionian — Mono Synth

The A Ionian lit key by key — roots pinned, degrees named, audio ready.

A Ionian carries 7 notes per octave (modes family), drawn here straight onto the Mono Synth's keys with every root pinned — no tablature in between, the keyboard is the map.

Bright, resolved, and stable. The foundation of Western tonal music and the most common mode in pop, classical, folk, and jazz.

Heard in: Pop, classical, country, folk, gospel — the default major tonality of Western music.

A scale is the one thing a mono synth never has to compromise: one voice is exactly what a line needs, and glide between adjacent keys is the idiom's signature.
