The ultimate map for every songwriter and guitar player. Learn how to transpose songs, find related chords, and understand music theory visually.
The key of C contains no sharps or flats.
On guitar, keys that are neighbors on the circle (like C and G) share 6 out of 7 notes. This is why moving between them feels so natural for songwriting.
The Circle of Fifths is more than just a theory diagram—it's a shortcut for guitarists. By organizing keys in a circle based on their relationship, it reveals perfect chord combinations for any song.
As you move clockwise, each key adds one sharp. As you move counter-clockwise, each key adds one flat. For a guitar player, this translates directly to fretboard positions and chord shapes.
Pick any key on the wheel. The keys directly to its left and right represent the IV and V chords. In C Major, those are F and G. These are the three chords used in 90% of rock and pop songs.
Need to move a song up a step? Just jump one segment clockwise on the wheel. All relationships (Major to Minor, I to IV) remain identical in their new positions.
Any group of six neighboring keys (3 outer, 3 inner) on the circle forms the diatonic family. For example, in C Major, the chords F, C, G and Dm, Am, Em represent the 1st through 6th chords of the scale. These six chords will always sound "correct" when played together on your guitar.
