About This Service

Chord Study is a web app specialized in music chord theory.

We're working toward an app that can be enjoyed by a wide range of people — from theory learners to composers, arrangers, and transcribers — with more features on the way.

※ This app is being developed partly as a personal music theory learning project, so there may be mistakes or bugs. If you notice anything, or have a feature request, please feel free to get in touch.

Features

• Chord Finder
