Scale Detail
Bb Aeolian — Bb B♭ Minor
The Bb natural minor scale (Aeolian mode) is the sixth mode of the major scale and the most commonly used minor scale. Dark, emotional, and deeply expressive, it is the foundation of minor key harmony in virtually every genre of Western music.
Formula: W – H – W – W – H – W – W
Dark, melancholic, emotionally deep, and dramatic. The definitive minor sound — the most common minor mode.
The Aeolian mode starts on the sixth degree of the major scale. Its formula W–H–W–W–H–W–W is the same as the natural minor scale. Starting on Bb, this gives Bb, C, C#, Eb, F, F#, Ab. Compared to the major scale (Ionian), Aeolian has three lowered notes: the third (♭3), the sixth (♭6), and the seventh (♭7). These lowered intervals are responsible for the minor, melancholic quality. The flat sixth distinguishes natural minor from Dorian (which has a raised sixth). The v chord in Aeolian is a minor chord (not dominant as in harmonic minor), which means phrases in natural minor often end on ♭VII – i rather than V – i. The relative relationship between major and natural minor is fundamental: C major and A natural minor share all the same notes — C major starting on A gives A natural minor.
The Aeolian mode is the natural minor scale — the second most common scale in Western music. Its half-step pattern creates a sense of melancholy, weight, and emotional honesty that has anchored countless songs across every genre.

Sonic Identity
The Aeolian mode — natural minor — is the foundation of emotional weight in Western music, anchoring everything from pop ballads to epic film scores. Its three lowered degrees (♭3, ♭6, ♭7) create a characteristic hollowness: not simple sadness but emotional complexity, weight, and honesty. The natural minor scale does not dramatize feeling — it inhabits it, with an authentic depth that resonates universally across cultures and centuries.
How Harmony Works
The im chord is the tonic, but it never achieves the finality of a major tonic — Aeolian always carries a slight sense of incompleteness. The ♭VII chord (a major chord a whole step below the tonic) provides the most natural cadential motion: ♭VII–i is the characteristic Aeolian ending heard throughout rock and pop. The v chord (minor, not the major V of harmonic minor) removes the strong leading-tone pull toward resolution, contributing to Aeolian's floating, melancholic quality. The ♭VI and ♭III major chords appear constantly in rock and pop for emotional lift within a minor key context.
