In music, the relative minor of a particular major key (or the relative major of a minor key) is the key which has the same key signature but a different tonic, as opposed to parallel minor/major. For example, G major and E minor both have a single sharp in their key signature; so we say that E minor is the relative minor of G major. The relative minor of a major key always has a tonic a minor third lower.

A complete list of relative minor/major pairs is:

  • C major - A minor
  • C sharp/D flat major - A sharp/B flat minor
  • D major - B minor
  • E flat major - C minor
  • E major - C sharp minor
  • F major - D minor
  • F sharp/G flat major - D sharp/E flat minor
  • G major - E minor
  • A flat major - F minor
  • A major - F sharp minor
  • B flat major - G minor
  • B/C flat major - G sharp/A flat minor

Together with moves to the dominant (fifth scale degree) or sub-dominant (fourth scale degree), modulation to the relative minor or major are the most common in tonal music.
