About this app
Improve your recognition of jazz progressions with a variety of exercises and features: - Study from hundreds of hand-curated chord progressions from easy to difficult, covering topics such as diatonic movements, diminished passing chords, modulations, and more. - Practice randomly generated chords or 2-5 movements to test difficult intervals and modulations. - Try progressions inspired by real jazz tunes, with options to tune the difficulty to your level. - Make your best attempt at the "daily song" and compare results with your friends! - Stats to track your streaks and how well you performed at each exercise. Aim for fewer mistakes, fewer listens, and faster completion.
