How do you want to start your idea?

Start from a musical idea and build it into a song in the Composer. ChordMini audio analysis is an early local beta and isn't available in this build yet.

The Composer is where the song gets built. ChordMini → editable analysis → Composer is the path we're enabling step by step.

Chord map workspace

Explore the demo preview, or load an MP3 locally to request local analysis when the FlowHarmony service is available on this device.

Load an MP3 locally, then choose Analyze source. Local analysis requires the FlowHarmony service on this device. Nothing is sent to production, and Composer remains unchanged.

Choose an MP3 to begin local analysis.
