Minor scales have a darker, more melancholic sound than major scales. There are three forms of the minor scale — natural, harmonic, and melodic — each with a slightly different character and purpose.
The Natural Minor Scale
The natural minor scale (also called the Aeolian mode) follows this pattern of whole (W) and half (H) steps:
W – H – W – W – H – W – W
Starting on A, this gives you: A – B – C – D – E – F – G – A — all white keys on the piano, just like C major. In fact, A minor and C major share the same notes. They're called relative keys.
Relative Major and Minor
Every major key has a relative minor that uses the same notes but starts on the 6th degree. To find the relative minor of any major key, go down three half steps from the root (or up to the 6th degree).
- C major → A minor
- G major → E minor
- F major → D minor
The Harmonic Minor Scale
The harmonic minor is a natural minor scale with the 7th degree raised by a half step:
W – H – W – W – H – A – H (A = augmented second, 3 half steps)
A harmonic minor: A – B – C – D – E – F – G# – A
The raised 7th creates a strong pull back to the root — similar to the leading tone in a major scale. This makes the V chord (the chord built on the 5th degree) a dominant 7th, giving it powerful harmonic tension. That's why composers and songwriters use harmonic minor: it gives you access to that driving V–i resolution while staying in a minor key.
The gap between the 6th and raised 7th (F to G# in A harmonic minor) creates that distinctive augmented second — an exotic, slightly tense sound you hear in flamenco, Middle Eastern music, and film scores.
The Melodic Minor Scale
The melodic minor raises both the 6th and 7th degrees when ascending, then reverts to the natural minor when descending:
- Ascending: A – B – C – D – E – F# – G# – A
- Descending: A – G – F – E – D – C – B – A (natural minor)
The ascending form smooths out the awkward augmented second from harmonic minor, making it easier to sing or play melodically. In jazz, the ascending form is used in both directions and is often just called "jazz minor."
Which Minor Scale Should You Use?
For most songwriting purposes, the natural minor is your default — it's what you get when you play "in a minor key" without thinking about it. Use harmonic minor when you want that strong pull to the tonic, especially for chord progressions. The melodic minor shows up more in classical writing and jazz, but its ascending pattern produces some interesting chords worth exploring.
