Relative Minor and Parallel Minor: Two Different Relationships

Relative minor and parallel minor are two different ways a major key relates to a minor key. Beginners often confuse them. The distinction matters because each relationship produces different harmonic effects in songs.

Relative Minor

The relative minor of a major key shares the same notes and the same key signature. It's just a different starting point.

The relative minor of C major is A minor. Both contain the same seven notes (A, B, C, D, E, F, G). The difference is which note feels like home. C major treats C as the tonic; A minor treats A as the tonic.

To find the relative minor of any major key, count down 3 half steps (or up 6th scale degree) from the major root. C minus 3 half steps is A. G minus 3 half steps is E. F minus 3 half steps is D.

Parallel Minor

The parallel minor of a major key shares the same root note but uses different scale notes. C major and C minor are parallel; they have the same root (C) but different scales.

C major: C, D, E, F, G, A, B. C minor: C, D, Eb, F, G, Ab, Bb. The 3rd, 6th, and 7th are flatted in the minor.

The parallel minor sounds darker than the relative minor because the chord qualities are different. Songs that switch from major to parallel minor (like the bridge of "Yesterday") create a dramatic mood shift.

Borrowed Chords

Songs in major keys often borrow chords from the parallel minor for color. The most common borrowed chord: bVII (the dominant 7th chord built on the b7 of the major scale, taken from the parallel minor's diatonic chords).

In G major, the bVII is F major. F isn't diatonic in G major, but it's borrowed from G minor (where it's the bVII). Songs like "Sweet Home Alabama" lean on this borrowed bVII.

Songs That Use Both

• "Yesterday" by The Beatles uses borrowed chords from F minor in the bridge.
• "Creep" by Radiohead uses Cm borrowed from G minor as a key chord.
• "Sweet Home Alabama" uses the bVII (C in the key of D) borrowed from D minor.

FAQ: Relative and Parallel Minor Questions

What's the relative minor of G major?

E minor. Both contain the same seven notes (G, A, B, C, D, E, F#). The relative minor is always the 6th scale degree of the major key.

What's the parallel minor of G major?

G minor. Same root note, different scale (G, A, Bb, C, D, Eb, F).

How do I find the relative minor of any major key?

Count down 3 half steps from the major's root. Or take the 6th scale degree.

What does it mean to "borrow a chord" from the parallel minor?

It means using a chord that's diatonic in the parallel minor but not in the original major key. The bVII (like F in the key of G) is the most common borrowed chord.

Why use borrowed chords?

For color. Borrowed chords create harmonic variety without leaving the key. They're a way to add minor-flavored mood to major-key songs.
