Tonic vs Functional Harmony

Tonic is the world's first AR chord dictionary. Chords are amazing. But for musicians who aren't jazz aficionados, finding a chord from a lead sheet is often frustrating and time consuming. And for the many talented musicians who don't read sheet music, chord dictionaries with music notation don't make things any easier. Tonic is the solution. Using AR, Tonic lets you easily view over 130 chords on your own piano. It tells you exactly where to place your fingers to play almost any chord. Great for students, professionals, or anyone interested in music. Features: - Over 130 chords with music notation - Flat/sharp display modes - Works with 88, 76, 61, 49, and 25 key pianos - 3 octaves to choose from - An adorable app icon
