hummonic

Hum a melody — Hummonic hears it and writes the chords underneath, voiced as real guitar fingerings you can actually play.

Jam with a band — strum your guitar and it follows: live chord detection, next-chord hints with diagrams, bass and drums that track whatever you play.

A coach, not a black box — it names your progression, tells you which famous songs share it, and suggests one concrete improvement at a time.

Finish the song — verses, choruses, melodies, and lyrics in ten languages, with version history so no idea is ever lost.
