FAQ

What is the circle of fifths?

A circular diagram arranging notes a perfect fifth apart, used as a fundamental music theory tool to visualize each keyโ€™s signature and the relationships between nearby keys.

What is a relative minor?

A minor key that shares the same key signature as a major key. For example, C major (no sharps/flats) has A minor as its relative minor.

Why does G come after C?

The circle of fifths is built by stacking notes a perfect fifth (7 semitones) apart. A perfect fifth above C is G. Repeating this step 12 times returns to C.
