Coffee Piano

Explore chord progressions and reharmonization in a browser piano studio.

Meet Coffee Piano

Coffee Piano is a browser studio for exploring harmony through sound and visual explanations. Users choose a key, mood, and difficulty level to generate chord progressions, then play them with sampled piano or Rhodes sounds. An on-screen keyboard and MIDI input support hands-on experimentation, including sustain-pedal use.

The Harmony Lab shows chord functions, alternative voicings, scale relationships, and guitar diagrams. Reharmonization controls let users change one bar or enrich a whole progression, with backing grooves available for improvisation. Players can record ideas, export progression MIDI, copy chords, and save projects locally, making the studio useful for learning, teaching, and composing.
