See harmony as a map and compose on it: chords are nodes, arrows are how harmony moves. Nine diagrams, chromatic chords and tonicized regions, tracks with comping styles, bass lines and your own drum grooves, a melody on a piano roll, scenes in their own keys and a whole song, analysis of any chord list or MIDI file, lessons, exercises and ear training, AI and your own agent, composing together in a room, recording to sound, and a way out to Band Jam, AI Music Charts and a public gallery with likes and remixes.
HARMONY MAP shows harmony as a map you compose on. Chords are nodes, and arrows show how harmony moves from one chord to the next.
You build tracks into scenes, arrange the scenes into a song and play it with sampled instruments, bass and drums. Each scene can have its own key. You can add comping styles, bass lines, your own drum grooves and a melody on a piano roll. Nine diagrams show the harmony, including chromatic chords and tonicized regions.
HARMONY MAP can analyse any chord list or MIDI file. Lessons, exercises and ear training teach the classic progressions, and the Learn page marks what you have done.
Your own AI agent can help. It can suggest the chords that can follow, reharmonise a progression, explain each chord's job, or write a melody over the chords. It never changes your song: everything it writes waits as a proposal that you open or discard.
You can compose together in a room, record to sound, and take your song to Band Jam, AI Music Charts or a public gallery with likes and remixes.
