Clockwise
Add sharps
Each step moves up a perfect fifth.
Circle of fifths
Use the circle of fifths as a map of harmonic relationships.
The circle organizes keys by perfect fifths, making it easier to see key signatures, neighboring tonal centers and common chord relationships.

Layout
Move clockwise by fifths and counterclockwise by fourths.
The circle shows how closely related major keys sit next to one another.
Counterclockwise
Add flats
Each step moves up a perfect fourth / down a fifth.
Relative minor
Shared key signature
Each major key has a relative minor with the same key signature.
Keys
Use the circle to compare tonal centers.
Neighboring keys share many notes and chords.
C ↔ G
One-note difference
Closely related keys.
C ↔ F
One-note difference
Another neighboring relationship.
Distant keys
More changes
Greater pitch-collection contrast.
Harmony
Map chord roots and functional movement.
Fifth relationships are central to many progressions.
V → I
Dominant resolution
A root movement by fifth.
ii → V → I
Cycle motion
Successive functional fifth relationships.
Turnarounds
Extended cycle
Longer progressions can trace parts of the circle.
