Circle of Fifths
The quickest way to see how keys are related and which chords go together.
The circle of fifths arranges the 12 keys so that each step clockwise moves up a fifth and adds one sharp (or removes one flat). Neighbouring keys share most of their chords, which is why they sound good together.
How to use the circle of fifths
- Pick a key. The numbers show how many sharps or flats it has.
- The keys on either side are the closest relatives: they share six of seven notes.
- Each outer major key has a relative minor in the inner ring that uses the same notes.
