Visualize harmony
Explore neighbors on an interactive graph, highlight suggested paths, and read clear explanations in the inspector.
Music theory you can see & hear
See where your harmony can go
Stuck after one chord? Chord Graph maps harmonic paths from your focus chord, explains every step in plain language, and lets you hear progressions before you commit.
What it is
Theory turned into a living graph
Pick a key, mode, and starting chord. Chord Graph builds a harmony graph around it—chords as nodes, real relationships as edges: diatonic motion, dominants, modal color, jazz substitutions, and more. Move from “what chord am I on?” to “what could happen next—and why?”
- Interactive canvas
- Ranked progressions
- Built-in playback
- Honest theory engine
