Questions
- What is the circle of fifths used for?
- It shows how keys relate. Neighbors on the circle share all but one note, which makes it useful for finding chords that fit a key and planning key changes.
- What are diatonic chords?
- The chords built from the notes of a key. In C major they are C, Dm, Em, F, G, Am and B°.
Better on a bench
On a bench, the key you pick on the circle sets the key for the fretboard and chord charts too.
