Harmony has a shape

Circle of Fifths

Choose a key to see what is close, what creates tension, and how those relationships become music.

Major keys are outside. Their relative minors are inside.

The big idea

Nearby keys share more notes.

The keys beside C major share six of its seven notes. That makes movement between them feel natural.

← Counterclockwise

F is the IV chord

Clockwise →

F creates movement→G creates tension→C feels like home

Build harmony

Seven notes become seven chords.

Stack every other scale note to build the chord on each degree. The major, minor, and diminished qualities happen naturally.

I, IV, and V are the main pillars of a major key. vi is its relative minor and a common emotional alternative to home.

C major

This is home: the most stable chord in the key and the place other chords resolve toward.

Common motionC → F

Why this order? Each clockwise move drops a fifth, a strong root motion heard throughout classical, jazz, pop, and folk harmony. The diminished vii° is included here because this wheel shows chords within one key—not key centers.
