Circle of Fifths Explained

The circle of fifths is a map of keys. Move clockwise and each key gains one sharp. Move counterclockwise and each key gains one flat.

How to read it

The outside letters are major keys. The smaller inside labels are relative minor keys. C major and A minor share the same notes, so they sit together.

Neighboring keys are closely related. In C major, the nearest keys are G major and F major. That is why progressions such as C, F, and G feel stable.

Why players use it

  • Transpose a song to a different key.
