Chord Graph vs Harmonaut

Chord Graph — see where your harmony can go Chord Graph turns music theory into something you can see and hear. Pick a key, mode, and starting chord, and the app builds a harmony graph around it: chords as nodes, real relationships as edges—diatonic motion, dominants, modal color, jazz substitutions, and more. Whether you write songs, teach, arrange, or practice at the keyboard, Chord Graph helps you move from “what chord am I on?” to “what could happen next—and why?” VISUALIZE HARMONY • Interactive graph centered on your focus chord • Tap neighbors to explore outgoing moves • Highlight suggested progression paths on the canvas • Inspector explains the selected chord or connection in plain language DISCOVER PROGRESSIONS • Ranked 4- and 8-bar progression ideas from your starting chord • Pop and Jazz style profiles that weight different harmonic moves • Next chord suggestions when you want one step at a time • Optional target ending chord to steer where a progression lands ANALYZE & EXPERIMENT • Suggest tools: paste chords from a lead sheet or sketch (e.g. two chords) and get completions or emotional alternatives • Progression analyzer for the path you’re exploring • Diatonic defaults: triads, sus chords, or 7ths—your choice HEAR IT • Built-in audio preview: play focus chords and full progressions • Tempo and loop for sketching ideas quickly • Stereo spread and reverb for a more musical audition BUILT FOR THEORY THAT STAYS HONEST ChordGraph is powered by a dedicated theory engine (keys, modes including major, minor, and common modes, triads through extensions, alterations, slash chords). Suggestions are scored and explained—not random chord wheels. WHO IT’S FOR • Songwriters looking for fresh cadences and bridges • Students learning functional harmony and jazz moves • Teachers demonstrating voice-leading and chord function • Keyboard and guitar players who think in chord symbols REQUIREMENTS Chord Graph is designed for Mac with a spacious layout: sidebar controls, harmony graph, and inspector working together. A future iPad version may follow; this listing reflects the Mac app. Start from any chord. Follow the graph. Hear the path. Understand the why.

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.
