Scale Detail
F# Mixolydian — F# F♯ Mixolydian
The F# Mixolydian scale is the fifth mode of the major scale — like the major scale but with a flat seventh. This single change removes the leading tone and creates a grooving, bluesy quality used in blues, rock, country, jazz, and gospel.
Formula: W – W – H – W – W – H – W
Bright but with a bluesy edge — the scale that sounds major but lacks the leading tone tension.
The Mixolydian mode starts on the fifth degree of the major scale. Its formula W–W–H–W–W–H–W is identical to the major scale except for a flat seventh. Starting on F#, this gives F#, Ab, Bb, B, C#, Eb, E. The flat seventh is the critical difference from the major scale — it creates a minor seventh interval above the root, making the tonic chord a dominant seventh. In contrast to the major scale's leading tone (one semitone below the root), Mixolydian's flat seventh sits a whole step below the root, removing the strong pull toward the tonic. This gives it a more relaxed, "laid-back" quality. Mixolydian is the scale of dominant seventh harmony — the V chord in a major key is naturally Mixolydian. Blues music extensively uses Mixolydian (often combined with the blues scale). The ♭VII chord (e.g., Bb in C Mixolydian) is a signature sound.
Mixolydian is a major scale with a lowered 7th degree — the sound of blues-infused rock, gospel, and earthy pop. By softening the leading tone, it feels more relaxed and earthy than pure major, yet retains a confident, grounded brightness.

Sonic Identity
Mixolydian is the "earthy major" — a major scale with a lowered 7th degree that removes the leading tone and gives the music a grounded, unresolved quality. The sound is bright and confident like Ionian but tinged with a bluesy, modal restlessness: it never fully commits to coming home. This perpetual forward motion is why Mixolydian became the DNA of rock, country, folk, and blues — familiar and optimistic, but with an undercurrent of perpetual motion.
How Harmony Works
The I chord in Mixolydian carries a dominant flavor — since the ♭7th appears naturally in the scale, the I chord can be voiced as a dominant seventh (I7) without leaving the scale. This dominant-tonic quality is the defining characteristic of Mixolydian harmony. The ♭VII chord is the mode's signature move: a major chord a whole step below the tonic that resolves easily back to I without the finality of a traditional V–I cadence. The absence of a leading tone softens V–I resolution, creating the open, rolling quality central to rock, blues, and Celtic music.
