Circle of Fifths
An interactive Circle of Fifths — the fundamental diagram showing the relationship between the 12 tones of the chromatic scale, their key signatures, and the major and minor scales built from them. Click a key on the circle to see its scale, relative minor, sharps or flats, and common chord progressions. Toggle between major and minor emphasis. Pairs with the Key Signature, Scale Generator, and Chord Identifier tools. Runs locally in your browser.
The circle clockwise adds a sharp (or removes a flat) at each step; counter-clockwise adds a flat. The inner ring shows the relative minor of each key. Enharmonic equivalents (e.g. C♯/D♭) are shown together. Pairs with the Key Signature and Scale Generator tools. Runs locally.
