GhostNote とは？

GhostNote is a browser-based, local-first music theory and practice workspace for musicians who want to understand harmony, not just memorize it. It brings together interactive tools for playing, analyzing, and practicing music in one place: virtual piano with Web MIDI support, chord progression tools, voice-leading analysis, and a structured practice academy. Runs fully in the browser and evolves through real user feedback into a complete music learning environment.
