Circle of Fifths

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

I love the simplicity of this app as someone who has been teaching myself to play guitar with no music theory knowledge I was looking for a way to see what chords and notes work well together thank you so much for this amazing app it does exactly what I need and keeps it simple enough for me to understand.. one suggestion.. having an option to see guitar tab in the centre as well as the treble clef and bass clef notation would be an awesome addition if it is possible, either way I love this app

Edit: Fantastic! All suggestions added to the app. I feel so spoiled. Zillion thanks!👍🎵🎶 Was: had 3 suggestions : - provide an alternate color theme with more contrast to identify M/m/dim chords - make the I, ll, lll, lV... buttons a little bigger and clikable (when lock mode is on) to hear the associated chord - provide an option to toggle chord or arpeggios when the chord is played (bonus: choice of couple arpeggios pattern) But its already perfect and useful as it is. Keep up 🤘!

Clean, easy on the eyes, functional, beautiful, free, I love it. It does what it says on the tin. If you're interested in adding to it, some small features like listing scales (like modes) or chord progressions would be really cool.
