Harmony Quest

Harmony Quest transforms ear training into an interactive musical journey.

Listen, compare, and recognize intervals, chord qualities, and harmonic progressions while developing your perception at your own pace.

Choose from different experiences:

• Journey: progress through guided challenges and track your musical mastery.

• Intervals: build chords note by note and understand the function of each sound.

• Chord Quality: recognize chords in harmonic and melodic forms.

• Progressions: follow the movement of degrees over a musical backing track.

The app works without login. Your progress and preferences remain only on the device. A one-time, optional purchase through Google Play unlocks Premium content and can be restored on other devices with the same account.

Harmony Quest is suitable for students, musicians, and curious individuals who want to understand harmony in a practical, visual, and auditory way.
