What is a Relative Minor?

A relative minor is a minor key that shares the same key signature as a major key. This means both keys use the same notes and accidentals, but they start on different root notes. Every major key has a relative minor that begins on the sixth scale degree of the major scale.

For example, the relative minor of C major is A minor. Both keys contain the same notes (A, B, C, D, E, F, and G) and have no sharps or flats in their key signature. The difference lies in which note acts as the tonal center, which changes the overall sound and mood of the music.

Relative minors are commonly used by composers to shift the emotional character of a piece while keeping the same key signature. Moving between a major key and its relative minor allows music to transition between brighter and more somber tones without introducing new accidentals, making it a useful tool in composition and harmony.
