The circle of fifths (Sometimes called circle of fourths) is a great tool for understanding the music theory behind the 12 keys of the chromatic scale. It is useful for visualizing the music notation of the different scales, composing chord progressions/modulations and mixing in key.

Features:
- Color-coded relationship between the major, minor and diminished keys
- Key signature and triad for each key
- A sounded chord/arpeggio for each key (With mute/unmute toggle)
- Ability to lock the circle to currently selected key
- A tappable legend indicating the degree of each key in the currently selected group
- Several color schemes
- Modern UI following material design guidelines

I hope you enjoy using this circle of 5ths app as much I as I enjoyed making it! Have fun! - Josh

A beautiful chord wheel app for musicians and DJs.
