Relative Major and Minor

Same notes, different root

C major: C D E F G A B. A natural minor: A B C D E F G. Count the notes in both. They are identical. The only difference is which note you start from and which note your ear treats as home.

How to find the relative minor

The relative minor is always the 6th degree of the major scale. In C major, count up to the 6th note: C, D, E, F, G, A. A is the relative minor. In G major: G, A, B, C, D, E. E is the relative minor. This works in every key without exception.

You can also go the other direction. To find the relative major of a minor key, go up three semitones (a minor 3rd). A minor is 3 semitones below C, so A minor's relative major is C. E minor is 3 semitones below G, so its relative major is G.

The same pentatonic shape works in both keys

This is the most practical application for guitarists. The A minor pentatonic shape and the C major pentatonic shape use exactly the same five notes (A C D E G). The box shape on the fretboard does not change. You just decide which note is home based on the chords underneath.

Over an Am chord, A is home. Over a C major chord, C is home. The same scale position, same hand shape, completely different harmonic function. This is why players who know one pentatonic shape already know two scales without learning a new shape.

Why the same notes sound so different

The emotional character of a key comes from which note the ear treats as a resting point. In C major, C feels resolved. Every phrase gravitates toward C. The C chord is home.

In A minor, A feels resolved. The Am chord is home. The exact same notes now have a different emotional weight because the tonal center changed. The intervals between the notes are the same but the meaning shifts because the reference point shifted.

This is also why a song can feel major or minor even when the key signature is ambiguous. The chord the song starts and ends on, and which note melodies tend to land on, tells your ear where home is. For more on the difference in character between major and minor, that guide covers it fully.

Relative keys and the circle of fifths

On the circle of fifths, relative minor keys are listed inside the circle, directly adjacent to their relative major. Every position on the circle represents one major-minor pair sharing the same notes. The visual makes it easy to see all twelve pairs at once.
