Formula
- Degrees: 1 2 b3 4 5 b6 b7.
- Steps: W H W W H W W (2 1 2 2 1 2 2 semitones).
- Parent scale: 6th mode of the major scale. A Aeolian = notes of C major from A: A B C D E F G.
- On C: C D Eb F G Ab Bb. On E: E F# G A B C D. On D: D E F G A Bb C.
It coincides with natural minor. In tonal theory the three forms of the minor (natural, harmonic, melodic) coexist in the same piece; in modern pop and rock one often stays in the natural form, i.e. in Aeolian.
Characteristic note and color
The signature of Aeolian, compared with the other minor modes, is the minor 6th (b6): it distinguishes it from Dorian (major 6th). Compared with Phrygian it has the major 2nd. Color: melancholic, serious, epic, nostalgic; the “default” minor of pop, rock, metal, trap and film music.
Diatonic chords (C Aeolian)
| Degree | Triad | Seventh |
|---|---|---|
| i | Cm | Cm7 |
| ii° | D° | Dø7 |
| bIII | Eb | Ebmaj7 |
| iv | Fm | Fm7 |
| v | Gm | Gm7 |
| bVI | Ab | Abmaj7 |
| bVII | Bb | Bb7 |
Signature chords: the major bVI and bVII and the minor v. Typical progressions:
- i – bVI – bIII – bVII (Am – F – C – G): the “epic loop” of pop-rock (a rotation of I–V–vi–IV).
- i – bVII – bVI – bVII (Am – G – F – G) and i – bVI – bVII – i: rock, metal, soundtracks.
- i – iv – v – i (Am – Dm – Em – Am): modal, no leading tone, folk flavor.
- bVI – bVII – i (F – G – Am): the “Aeolian” cadence, a minor alternative to V – i (widely used in metal and film music; the “Mario cadence” in major).
Aeolian and tonal minor
When a minor-key piece uses a major V (E in A minor, with G#) it passes to harmonic minor: this is normal practice in classical music. The pure Aeolian color, without a leading tone, is more “modal” and modern. Many songs alternate: an Aeolian verse with a minor v, a chorus with a major V to increase tension.
Use in genres
- Rock and pop-rock: “All Along the Watchtower” (Jimi Hendrix, C#m – B – A – B: i – bVII – bVI – bVII), “Zombie” (The Cranberries, Em – C – G – D: i – bVI – bIII – bVII).
- Pop: “Rolling in the Deep” (Adele), in C minor, built on Aeolian chords (Cm, Gm, Bb, Ab).
- Trap and hip hop: melodies and 808s almost always in natural minor (or harmonic), piano loops i – bVI.
- Metal: Aeolian as the base, with Phrygian and harmonic minor as added colors.
- Film: epic and melancholic themes, often with bVI – bVII – i.
Melodies and basses
- Resting notes: 1, b3, 5. Expressive notes: the b6 falling to the 5, the 2 falling to the 1.
- In the bass: stepwise descents 1 – b7 – b6 – 5 (the “lament” descent, A – G – F – E, which leads to the Andalusian cadence).
Common mistakes
- Using the Aeolian scale over a major V (E7 in A minor): the G natural against the chord's G# clashes. Over the V use harmonic minor (or Phrygian dominant).
- Inserting the major 6th (F#) in the melody out of habit: it becomes Dorian.
- Believing that “minor” always means Aeolian: always check the 6th and the 7th.
Exercise
- Loop Am – F – C – G at 90 BPM: write a topline that leans on the b6 (F) over the F chord and resolves it to E.
- Rewrite the same loop with E major in place of G in the last bar: listen to the shift from Aeolian to harmonic minor.
- Write a bVI – bVII – i cadence to end a piece without using the leading tone.
