Coffee Piano: A browser-based piano studio with visual harmony tools for musicians
By
Jaime
Sat on the counter overnight. Well past its best.
Summary
Coffee Piano is a browser-based music tool that combines a real piano and Rhodes sound engine with visual harmony features. It offers orbital scale and chord maps, smart progression generation, reharmonization, guitar diagrams, MIDI support, and a sustain pedal — all without installation. The tool bridges the gap between sound engines with no music theory and theory references with no sound, targeting musicians who think in harmony.
Key quotes
· 4 pulledI built Coffee Piano because there was no tool that let you hear a chord idea, see it as a visual map, and understand the harmonic logic behind it, all in the same place.
Most tools are either a sound engine with no theory, or a theory reference with no sound. That disconnect is what Coffee Piano solves.
It brings harmony to life visually through orbital scale and chord maps, a real piano and Rhodes engine with MIDI, smart progression generation, reharmonization, and guitar diagrams, all in the browser.
Built for musicians who think in harmony, not just in notes.
