Chord Wheel helps you to understand how music works. Also, it helps you to get some musical ideas for your own songs.The Interactive Chord Wheel is an implementation of one of the most basic and significant music theory, Circle of fifths on Android. This app is uniquely designed to represent the relationship between a scale and a chord. In the screen of this app, the Circle is made up of several concentric rings, which provides various information. By rotating the 2 rings, inner and outer, the needed information can be got easily.The outer most ring shows information on the scale such as a tonic, a dominant, a sub-dominant, a relative minor, a relative major, and a progression of the degree. The next outer ring shows a series of notes name ordered by the progression of 5th, and the root note of a scale can be set by rotationg this ring. When rotating the outer ring, the inner ring rotates also. The next ring shows a degree of a note and a diatonic chord in that scale. By rotaing the next ring, a chord can be set. If a note name of the outer ring is touched, then a diatonic chord, of which the root note is the note, is set. Instead of the inner chord ring, a key progression ring can be displayed which is very useful when transposing a song to another key. At the center of the concentric rings, a signiture of the scale is displayed. The direction of the circleThe direction of the key progression on a circle can be set to a CW or a CCW direction by a user. Switchable Inner WheelThe inner wheel can be switched when it is needed. A chord wheel, a transpose wheel, and a interval wheel are avalable.ScaleA major scale and 3 minor scale and church modes are available. The scale tones can be distinguished by its background color. A diatonic chord of the scale can be set by touching one of its scale tones. Diatonic Scale ChordBoth triads and 7th chords are supported for each scale.Chord WheelChord wheel is uniquely designed to represent the relationship between a scale and a chord. Most diatonic chords are available. The chord tones can be distinguished by its background color or its mark.

A GREAT APP

thomas stafford

Great app but it's been abandoned by the developers.

Luis Ureña

Great little app. Very practical, no fluff. Finding it very good for writing chord progression. Particularly like that it shows chords of minor keys too.

Rael39

I use it weekly to find what chords I need for any song.

Dave Klinedinst

Excellent. Works like a dream.

Mike Caffyn

handy reference tool

Miikka Ekholm

Very good. Used it for a couple of years, but new droid 10 phone now asks for app upgrades.

David Valentine-Hagart

Pro: app can be moved to external SD memory. And, the "transpose "function" is very usefull. Con: there is no selection to have the minor key chords displayed inside the major key chords. (example: A minor inside/below C major)

Robert Paul Bergsman

This app is really good for music theory and knowing your progressions, but it needs to be updated for new Android versions. It keeps popping that it may be unstable. Last update was 2014, so it costs more than 4$ and the developers haven't done anything to the app since then, I believe.

Love this app and how it works. Just moved to iOS and miss it a lot. Similar apps try to do too much and don’t get the basics right. Would love a port to iOS
