Today we’re going to look at the ‘Circle of Fifths’. You may have come across the term before, or the ‘Circle of Fourths’, or just ‘The Circle’.
Check out the diagram below and then we’ll look at what it means and why its useful.

As you can see if we move clockwise in The Circle of Fifths we go up in fifths, e.g. C to G. If we move anti-clockwise we go up in fourths, e.g. C to F. The inner ring shows the relative minor key of each Major key. For example the relative minor to C Maj is Am. The relative minor of G Maj is Em etc.
