Relative Major and Minor Keys Explained

Quick answer: what are relative keys?
A relative major and minor are two keys that share the same key signature and the same seven notes, but start from different home notes. C major and A minor are relatives: neither has any sharps or flats. To find the relative minor of a major key, go down three semitones (a minor third), or up to the sixth note of the scale.
The idea in one sentence
Take the notes of the C major scale: C D E F G A B. Now start on A instead: A B C D E F G. It is the same seven notes, but because the music now centres on A, it sounds minor. A minor is the relative minor of C major, and C major is the relative major of A minor. Musicians also use the word "relative" for any pair that works this way, which the Wikipedia article on relative keys describes as keys sharing a key signature but not a tonic.
How to find the relative minor
There are two quick routes, and both give the same answer.
Method 1: count the semitones. Start on the major tonic and move down three semitones (a minor third, or "minor 3rd"). From C that lands on A. From G it lands on E. From F it lands on D.
Method 2: use the scale. The relative minor starts on the sixth note (the sixth degree) of the major scale. In G major (G A B C D E F♯), the sixth note is E, so E minor is the relative minor.
How to find the relative major
Go the other way. From the minor tonic, move up three semitones, or use the third note of the minor scale. In A minor (A B C D E F G), the third note is C, so C major is the relative major. In D minor, up three semitones from D gives F, so F major is the relative major.
Relative keys chart
Here are some common pairs. Each pair shares the same key signature. If you want to see how these signatures are built, read our guide to key signatures.
| Major key | Relative minor | Key signature |
|---|---|---|
| C major | A minor | No sharps or flats |
| G major | E minor | 1 sharp (F♯) |
| D major | B minor | 2 sharps (F♯, C♯) |
| A major | F♯ minor | 3 sharps (F♯, C♯, G♯) |
| F major | D minor | 1 flat (B♭) |
| B♭ major | G minor | 2 flats (B♭, E♭) |
| E♭ major | C minor | 3 flats (B♭, E♭, A♭) |
Relative keys vs parallel keys
People often mix these up. Relative keys share a key signature but have different tonics (C major and A minor). Parallel keys share the same tonic but have different key signatures (C major and C minor). C major has no flats, while C minor has three, so the sound changes a lot even though the starting note stays the same.
Why relative keys matter
Because the two keys use the same notes, moving between them feels smooth. Songwriters often switch from a major verse to a minor chorus, or the reverse, without changing the key signature. Composers also treat relative keys as some of the most closely related keys when they modulate (change key) in the middle of a piece. When you read sheet music, a key signature on its own does not tell you whether the piece is major or minor, so listen to where the music feels "at rest" and check the final chord. Our guide to major vs minor scales explains the sound difference, and the circle of fifths shows every relative pair on one diagram.
Try it on an instrument
Open the chord and scale explorer, play C major, then play A natural minor and compare the notes. You will see the same keys light up. In real music, minor keys often raise the seventh note (the harmonic minor), so you may meet an extra sharp or natural in a minor piece even though the key signature stays the same. For the chords that live inside each key, see triads explained.
Frequently asked questions
What are relative major and minor keys?
Relative keys are a major key and a minor key that share the same key signature, so they use exactly the same notes. They have different tonics (home notes). C major and A minor are the classic pair.
How do you find the relative minor of a major key?
Count down three semitones (a minor third) from the major tonic, or go to the sixth note of the major scale. From C major, the sixth note is A, so A minor is the relative minor.
How do you find the relative major of a minor key?
Count up three semitones (a minor third) from the minor tonic, or go to the third note of the minor scale. From A minor, the third note is C, so C major is the relative major.
What is the difference between relative and parallel keys?
Relative keys share a key signature but have different tonics, such as C major and A minor. Parallel keys share the same tonic but have different key signatures, such as C major and C minor.
