The ultimate music theory reference tool for musicians of all skill levels. Tonality allows you to view and listen to a large database of piano chords and scales and features a chord-recognition tool that can identify chords you play on your instrument.

    Great app for musicians of all skill levels! I've been playing piano for a few years and this app is helping me practice my scales and understand basic music theory. I can even add my own scale fingerings! The identify chords feature was extremely useful. Would highly recommend this app to anyone passionate about music and seeking to learn more.
