Earpeggio is an ear training app that improves musical hearing. Master the identification of intervals, chords, scales and rhythms solely by hearing them. The app has a guided mode that takes you through a number of increasingly difficult challenges.

To create this app, we have used Appleā€™s Core Audio libraries to generate and play the notes and chord progressions. One of the design challenges was to present a large number of options without using a list. This way users can develop muscle memory and focus on the challenge instead.
