Getting-started
You'll need a MIDI keyboard to use Chordzy; see the hardware help page for more.
Playing
Chordzy can run right in your web browser, and you don't even need an account to get started.
Some features are only available in the app, or with an account. Accounts are free to create, and only a minimal number of features require a subscription.
Skill Levels
Each song (or exercise) is broken down into smaller pieces. You'll learn to play each hand independantly on the piano, then put them together and build speed. At higher levels, Chordzy even tests advanced technique (like dynamics).
