The Mixolydian Mode
Mixolydian is the major scale with its 7th degree relaxed — trading the leading tone's tug toward home for a looser, bluesier, dominant-chord feel.
What is the Mixolydian mode?
The Mixolydian mode is built on the 5th degree of a major scale. It's a major mode — its 3rd and 6th degrees stay natural, just like Ionian — but Mixolydian lowers the 7th degree by a half step, replacing the sharp, pulling leading tone with a relaxed flat 7th.
Scale degrees: 1, 2, 3, 4, 5, 6, ♭7. That single flat 7th is the only difference from Ionian, and it changes the mood from "resolved" to "groovy and unresolved."
The characteristic note
Mixolydian's identity is its flat 7th (♭7). In the major scale, the 7th degree is a leading tone that sits just a half step below the tonic and pulls hard toward it. Flatten that note and the pull disappears — the scale can groove and vamp on its tonic chord indefinitely without feeling like it needs to resolve anywhere.
Where you'll hear it
Mixolydian's flat 7th is baked directly into the dominant 7th chord (1–3–5–♭7), which is why the mode shows up constantly in blues and blues-derived rock. It's especially at home in blues-rock and jam-band music, where extended vamps on a single dominant-flavored chord let the flat 7th's relaxed color shine without needing constant harmonic motion.
Common questions
What is the Mixolydian mode formula?
W-W-H-W-W-H-W. Scale degrees are 1, 2, 3, 4, 5, 6, ♭7 — the major scale with a lowered 7th degree.
Why does Mixolydian sound bluesy?
Its flat 7th removes the leading tone's pull back to the tonic, giving Mixolydian a relaxed, unresolved, dominant-chord quality that blends naturally with blues phrasing.
What chord is built from Mixolydian?
A dominant 7th chord (1, 3, 5, ♭7) is built directly from Mixolydian's first, third, fifth, and seventh degrees.
Where is Mixolydian used in music?
It's common throughout blues-rock and jam-band music, where its flat 7th supports riffs and grooves that stay relaxed rather than driving hard back to the tonic.
