The Aeolian Mode
Aeolian is the mode you already know by another name: the natural minor scale. It's the default darker minor sound, and Ionian's opposite number across the brightness spectrum.
What is the Aeolian mode?
The Aeolian mode is built on the 6th degree of a major scale — which means it is the natural minor scale. Just like Ionian and major, Aeolian and natural minor are two names for the same seven-note pattern; it gets its own name because it takes its place in the family of seven modes.
Scale degrees: 1, 2, ♭3, 4, 5, ♭6, ♭7. This is the same "plain minor" pattern you may already know — here it's presented in its modal context, right between its brighter sibling Dorian and its darker sibling Phrygian.
Where you'll hear it
Aeolian is the default sound of minor-key music, the same way Ionian is the default sound of major-key music. Whenever a song is described simply as being "in a minor key" without any raised leading tone or jazzy 6th, it's almost certainly drawing straight from Aeolian — it's the plainest, most common minor mode across rock, pop, and classical writing.
Common questions
What is the Aeolian mode?
Identical to the natural minor scale: W-H-W-W-H-W-W. It's built on the 6th degree of a major scale and is the reference point for "plain" minor among the seven modes.
Is Aeolian the same as the natural minor scale?
Yes — Aeolian and natural minor are exactly the same seven-note pattern. "Aeolian" is the modal name used when discussing it alongside its six sibling modes.
Why does Aeolian sound darker than Dorian?
Aeolian lowers the 6th degree where Dorian keeps it natural. That one lowered note is the entire difference, and it makes Aeolian feel darker and more resigned than Dorian's brighter minor color.
Where is Aeolian used in real music?
Extremely widely — most pop, rock, and classical melodies described as being in a minor key are drawing on the Aeolian mode, making it the default sound of minor-key music.
