FreeMIDIChords
Free music theory tools for every platform

FreeMIDIChords is a free, open-source suite of music theory tools including chord detection, interval detection, circle of fifths, scales, and a metronome. It is available as a web app, mobile app (iOS and Android), desktop app (Mac, Windows, and Linux), and a dedicated controller for the Roland FP-30X. No account or download is required to use the web version, and the project is designed to remain free and ad-free.
Users open the web app or install the native app on their platform of choice to access chord detection, generation, scales, and other music theory tools, with optional MIDI keyboard input.
