About
Most harmony tools are too theoretical or too simple. Coffee Piano combines a real piano studio, sampled Piano & Rhodes, MIDI, sustain pedal with a visual harmony engine. Orbit visuals show scales and chords as circular maps. A harmony map reveals voice leading and chord function. Reharmonize in one click per bar or full progression. Guitar diagrams sync to every chord. Works in the browser, no install, bilingual UI.
AI Summary
Coffee Piano is a browser-based music and piano studio that integrates visual harmony tools with a real piano experience. It features a unique visual engine for scales and chords, MIDI support, and bilingual functionality, allowing users to easily explore and manipulate harmony.
