The Circle Of Fifths Explained

The Circle of Fifths is a visual representation of the relationships between the 12 tones of the chromatic scale, their corresponding key signatures, and the major and minor keys. It’s a helpful tool for musicians, particularly in understanding key relationships, chord progressions, and transposing music. Here’s a breakdown of the Circle of Fifths:


  • The circle is divided into 12 sections, each representing one of the 12 pitch classes.
  • The pitch classes are arranged in ascending order of fifths (or descending order of fourths) around the circle.

Key Signatures

  • Each section of the circle corresponds to a specific key.
  • The key signatures are written in a clockwise direction, starting at the top with C major, which has no sharps or flats.
  • As you move clockwise, each new key adds one more sharp to the key signature.
  • As you move counterclockwise, each new key adds one more flat to the key signature.

Order of Keys

  • Moving clockwise, the order of keys is: C major – G major – D major – A major – E major – B major – F# major – Db major – Ab major – Eb major – Bb major – F major.

Order of Keys (Counterclockwise)

  • Moving counterclockwise, the order of keys is the reverse: C major – F major – Bb major – Eb major – Ab major – Db major – F# major – B major – E major – A major – D major – G major.

Relative Minor

  • The relative minor key of each major key is located just inside the circle, sharing the same key signature. For example, the relative minor of C major is A minor.

Chord Progressions

  • The Circle of Fifths helps musicians understand chord progressions. Chords that are adjacent on the circle are likely to sound good together in a progression.


  • Musicians use the Circle of Fifths to transpose music. If you want to transpose a piece to a different key, you can follow the circle to find a key with the desired number of sharps or flats.

Harmonic Relationships

  • The Circle of Fifths visually demonstrates the harmonic relationships between keys. For example, the dominant chord in a key is located a fifth above the tonic.

Understanding the Circle of Fifths is valuable for musicians as it provides a clear visual reference for key relationships and can aid in various aspects of music theory and practice.
