Eb minor

Construction

Step pattern (W = whole step, H = half step): W-H-W-W-H-W-W.

Formula (intervals from the root): 1-2-b3-4-5-b6-b7.

Natural minor is the minor scale in its purest modal form -- no alterations to create leading tones or smooth out intervals. The b3 defines the minor quality, while the b6 and b7 together give it a darkness that Dorian and melodic minor avoid.

Origin and Relationships

Natural minor is a mode -- a scale derived by starting a parent scale from a different degree. It belongs to the diatonic modes family as the 6th mode of major.

• Parent: major starting from its 6th degree. To find the parent, go up a minor third (3 half steps) from the natural minor root.
• Compare to Dorian: natural minor has b6 where Dorian has a natural 6. That single note shifts the character from warm to dark.
• Starting from each degree produces the same seven modes as major, reordered.
• Part of the minor system with harmonic minor (raises the 7th for a leading tone -- a note one half step below tonic that pulls upward) and melodic minor (raises both 6th and 7th, smoothing the augmented second -- 3 half steps -- between b6 and 7). Natural minor keeps both lowered. Choose natural minor for modal color, harmonic minor for a strong V chord, melodic minor for smooth ascending lines.

Harmonic Context

In Roman numeral analysis (uppercase = major, lowercase = minor):

• i (minor): Tonic home base.
• ii° (fully diminished -- stacked minor thirds): Unstable supertonic, often extended to a half-diminished seventh (a diminished triad with a minor 7th added).
• bIII (major): Relative major. Bright contrast to the minor tonic.
• iv (minor): Subdominant. Deepens the minor quality.
• v (minor): Without a leading tone pulling up to tonic, the minor v cannot drive a strong resolution the way a major V7 can. This is natural minor's core harmonic limitation and why harmonic minor was developed.
• bVI (major): Common in rock and pop minor progressions.
• bVII (major): Subtonic. Powers Aeolian cadences like bVII-bVI-v-i.

Characteristic Tones

The intervals that give this scale its distinctive sound:

• b6 (minor sixth): The tone that separates Aeolian from Dorian. Compare to Dorian: Aeolian has b6 where Dorian has a natural 6 -- that one note shifts the mood from warm and jazzy to dark and melancholic.
• b7 (minor seventh): Sits a whole step below tonic -- no leading tone pull. The b7 keeps natural minor modal, which is why strong cadences in minor keys bring in the raised 7th from harmonic minor (temporarily using a note outside the scale for dominant function).
• b3 (minor third): Defines the minor quality. Establish it early in any phrase so the ear registers "minor" before other tones add their color.

Melodic Applications

Target the b6 to distinguish Aeolian from Dorian -- it is the note that makes natural minor sound sad rather than warm. The b7 avoids strong resolution, so use natural minor when you want modal color without dominant drive. For cadences that need a strong V7, bring in the raised 7th from harmonic minor; for pure Aeolian color, keep the b7 and let phrases settle gently.

Practice Seeds

b6 emphasis. Play phrases that highlight the b6, then swap it for a natural 6 (Dorian). Hear how one note transforms the mood from dark and plaintive to warm and inviting -- this is the Aeolian-Dorian divide.

Relative major. Find the relative major by starting from b3. Play the same notes with each root and hear how the identical pitch set creates completely different emotions depending on which note is home.

Weak v chord. Play i-v-i using natural minor's minor v chord. Feel the absence of resolution pull -- then play i-V-i with the raised 7th from harmonic minor and hear the difference. This is why harmonic minor exists.

Minor system comparison. Play natural minor, then harmonic minor (raise the 7th), then melodic minor (raise both 6th and 7th) from the same root. Hear what each alteration adds and why composers choose one over the others.
