Our verdict on Harmony Map
Harmony Map is a browser-based composition and learning tool from AIMEAT for people who want to explore chord relationships and turn progressions into song arrangements. Its chord map displays chords as connected nodes, with selectable key, mode, chord set, and diagram. Users can compose progressions, edit beat placement, and arrange scenes into songs with multiple tracks. Guided progression lessons and ear training also make it relevant to learners, while MIDI export and chord-text copying support moving ideas into other workflows.
The harmony tools focus on relationships rather than genre presets: users can toggle secondary dominants, borrowed chords, and voice leading. For arranging, scenes can include drums and optional auto bass from chord roots. The current scene can be exported as MIDI; songs can be shared by link or saved to an AIMEAT account. This suits solo composers and learners looking for a web-based way to map harmony and develop arrangements, but it is a narrower choice for anyone seeking genre-style generation or plugin formats.
AI suggestions and track reharmonization are available through the user's own OpenRouter key. Alternatively, the app offers a copy-to-AI workflow: song data can be copied into an AI chat and returned JSON applied. That makes AI assistance an option rather than a prerequisite, though in-app use depends on arranging access to a personal key. The app is free, and the published description identifies no paid tiers. Choose Harmony Map for visual harmony exploration, lessons, and lightweight song-building in a browser; consider another tool if you need a standalone AI service without an external key or whole-song MIDI export.
