The Minor Scale — natural, harmonic & melodic

"The minor scale" is really three closely related scales that differ only in their 6th and 7th degrees. The natural minor (1 2 b3 4 5 b6 b7) is the default — in A: A, B, C, D, E, F, G. The harmonic and melodic variants each raise a degree to solve a specific musical problem.

Natural minor — the home base

Same notes as the relative major starting on its 6th degree (A minor = C major's notes), which is why every minor key shares a key signature with a major one. If a song is "in A minor", this is the default note pool. The minor pentatonic is this scale minus the 2 and b6.

Harmonic minor — the raised 7th

Natural minor's problem: its v chord is minor, so V–i resolutions sound soft. Raise the 7th (G → G# in A minor) and the V chord becomes major — E7 pulling hard to Am. That raised 7th also creates the scale's signature exotic gap between b6 and 7, the flamenco-and-neoclassical sound:

A harmonic minor — the G# creates the E7→Am pull — root notes in green.

Melodic minor — the smoothed ascent

Harmonic minor's b6→7 leap is awkward to sing, so melodic minor raises the 6th as well on the way up (classically, it reverts to natural minor coming down). For improvisers it's a scale in its own right — jazz players run it over minor-major and altered-dominant sounds:

In practice, songs in minor keys borrow the harmonic minor's major V (E instead of Em in A minor) exactly when they want that stronger pull home.
