Circle of Fifths

Josh Liebe

About this app

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

Ratings and reviews

This app is amazing! No ads, no paywall, and works perfectly fine. It's just like Hal Leonard's Chord Wheel, except it's free and interactive. It would be nice to be able to customize the chords (voicings and inversions) and add extensions and such. It would also be great to have some sort of chord progression generator/builder. Finally, the color schemes are nice, but I would be interested in being able to add personalized cholor schemes. Besides that though, this app is perfect.

It's simple and right to the point. One thing that is missing: The outer part of the circle changes the key. However, if I want to stay in the key of C major and hear the sound of G dominant 7, I can't do it. As soon as I hit on the G, it switches to G major, thus playing the GM7 chord. Is there a way to make it sound the the dominant 7th? Maybe add a "lock feature" to lock it in the key, for instance, "C". It will have an option to lock so it plays all of the root chords of every mode?

I love this app and recommend it to my students. There's so much information here! For the longest time, I didn't even notice the grey part of the circle that shows all the diatonic notes of each scale!
