Tonality: Piano/Guitar Chords

Bryce Hostetler
"Best music app tool I own, period!"
"Never downloaded an app so fast in my life"
"Excellent app for music theory. It is brilliantly supported by the developer who is continually updating it and adding more features. The app is indispensable for the reference and learning of music theory."

The ultimate chord, scale, and music theory reference tool for musicians of all skill levels. Tonality allows you to view and hear a large database of piano/guitar chords and scales. You can run Tonality as an AUv3 MIDI receiver and view piano chords that match MIDI input you route to it, or as a MIDI source and send chords to other apps.
