"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.

CHORDS:
- Chord dictionary with over 1,000 chords for piano and guitar
- Listen to a piano chord by tapping on it, or arpeggiate by swiping left or right
- Search for chords by root, quality, extension, or any combination of these
- Reverse search for chords containing certain notes (on piano or fretboard)
- Sort chords by key, number of pitches, key span, and more
- View different inversions and omittable notes
- View a table of related scales (especially useful for jazz musicians learning to improvise)
- Chord identification - record a chord through your device's microphone and Tonality will transcribe and identify it. Options include overtone rejection and tuning forgiveness.

GUITAR CHORD CHARTS:
- View guitar chord charts for all chords (even custom ones)
- Fully interactive – swipe across the strings to play each voicing
- Supports multiple guitar tunings and other instruments such as ukulele, mandolin, banjo, and bass
- Generation by traits such as fret range and number of fingers used
- Left-handed option

SCALES:
- Scale dictionary with over 500 scales
- Commonly used piano scales and fingerings
- Search for scales by root and name

- View scale degrees and note names
- View ascending and descending versions
- View scales on a piano and in the staff
