Minor Scales on Piano

Minor scales come in three forms — natural, harmonic, and melodic — each with a different sound and a different role in Western harmony. The natural minor is the foundation; the harmonic and melodic forms add chromatic adjustments to solve specific musical problems.

Natural Minor Scale →
Formula: W–H–W–W–H–W–W
Degrees: 1–2–♭3–4–5–♭6–♭7
Sound: Dark, melancholic, expressive
The foundational minor scale — also known as the Aeolian mode. Used for melody and as the source for diatonic minor harmony.
Harmonic Minor Scale →
Formula: W–H–W–W–H–W+H–H
Degrees: 1–2–♭3–4–5–♭6–7
Sound: Exotic, dramatic, Spanish
Natural minor with a raised 7th — creates a leading tone for stronger V→i cadences. The 7th degree creates a distinctive augmented 2nd interval.
Melodic Minor Scale →
Formula: W–H–W–W–W–W–H (ascending)
Degrees: 1–2–♭3–4–5–6–7
Sound: Smooth, jazzy, sophisticated
Raised 6th and 7th ascending for smooth upward motion — the foundation of jazz minor harmony. Classically descends as natural minor.

Why three forms? The natural minor scale lacks a leading tone — its 7th degree is a whole step below the tonic, which weakens the V→i cadence. Composers solved this by raising the 7th (harmonic minor), but that created an awkward augmented 2nd between the 6th and 7th. Raising the 6th too (melodic minor ascending) smoothed out the line. Each form serves a specific musical purpose.

Looking for the modal counterpart? The natural minor scale IS the Aeolian mode — same notes, different framing as the 6th mode of the major scale.
