Harmonaut is a chord instrument you play by feel. Press a key and it voices a rich chord for the moment — no theory, no wrong notes. Two faders let you shape the mood as you play: more tension or less, brighter or darker, even major to minor. Chase a moody electronic progression, a warm lo-fi loop, a cinematic swell, or a simple pop hook — it all comes from your intent, not from naming chords. HOW IT PLAYS • Tension that actually resolves — chords that lean, pull home, and land, so your progression goes somewhere instead of just floating • Every one of the twelve keys is in play — reach past the obvious chords for richer, more surprising color, and it still sounds right • Build a whole progression, not just four chords — every chord you play lands in your trail, ready to reorder or duplicate to try new versions in seconds • Pick up right where you left off — your ideas are saved for you IT SOUNDS GOOD FOR A REASON Harmonaut connects your chords with smooth voice leading, so a progression flows instead of clunking — that finished feeling you hear in the songs you love. And it names every chord the way musicians actually write it — Ebmaj7 — so you can hand your progression to a session player, a bandmate, or a producer and they'll read it and play it back exactly, first time — no re-explaining. You're speaking their language without having to learn it. And because it's built on how harmony really works — not a random generator — every chord it hands you genuinely works. However much theory you know, it just sounds right. No box to buy, nothing to charge, no menus to dig through — it's already in your pocket. Whether it's your first progression or a sound you can hear but can't name, Harmonaut meets you where you are.
