What is the Circle of Fifths?

The circle arranges all 12 keys so that each step clockwise is a perfect fifth higher (7 semitones). Going counter-clockwise is a perfect fourth.

Outer ring = Major keys  |  Inner ring = Relative minor keys (same notes, different root)

Keys that are next to each other on the circle share the most notes in common — they sound great together. Keys on opposite sides share the fewest notes.

The highlighted slice shows your currently selected root. Click any slice to change the root on the fretboard.

💡 Tip: The relative minor is always 3 semitones below (or 9 above) its major. C major → A minor. Same notes, different feel.
💡 For your guitarist/pianist: if you're in C# minor (Aeolian), your pianist can think of it as E major — same scale, same notes.
