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.
