F# Mixolydian Mode
F#–G#–A#–B–C#–D#–E · root also written Gb
F# Mixolydian is the 5th mode of the B major scale: F#–G#–A#–B–C#–D#–E. Its character: bluesy, rocking, and unresolved — major with a laid-back edge.
The flat 7th is the one note that separates Mixolydian from major. It creates a dominant 7th chord off the root and gives the scale a bluesy, unresolved quality — sounds major but wants to move. On guitar, target the flat 7th (E) in your phrases — landing on it against the root is what makes a line sound Mixolydian instead of plain major.
Because every mode of B major shares the same seven notes, any B major fretboard shape works for F# Mixolydian — what changes is the note you resolve to. Loop a F# vamp or a backing track that stays on F#, keep resolving your phrases to F#, and the Mixolydian color comes through. You'll hear this sound in rock, blues, funk and country.
F# Mixolydian is mode 5 of B Major — same seven notes, resolved to F# instead.

Songs That Use the Mixolydian Sound
The Beatles — “Norwegian Wood”
In E Mixolydian. The sitar-influenced melody uses the D natural (flat 7th) throughout, giving the song its distinctively modal, folk-rock quality.
Grateful Dead — “Fire on the Mountain”
In B Mixolydian. The repeating two-chord vamp (B to A) defines Mixolydian harmony — the flat 7th chord (A) under a B root. Jerry Garcia's solos stay in B Mixolydian throughout.
AC/DC — “Highway to Hell”
In A Mixolydian. The progression (A–D/F#–G–D/F#–A) uses the G chord (flat 7th) which is the Mixolydian signature. Angus Young mixes A major pentatonic with the flat 7th in his solos.
Lynyrd Skynyrd — “Sweet Home Alabama”
Also operates in D Mixolydian over the D–C–G progression. The C chord (flat 7th of D) is the Mixolydian marker. The interplay between major pentatonic and Mixolydian is what gives southern rock its sound.
F# Mixolydian Mode FAQ

F# Mixolydian is the 5th mode of the B major scale — the same seven notes starting from F#: F#–G#–A#–B–C#–D#–E. The interval formula is R–2–3–4–5–6–♭7.
What is the difference between F# Mixolydian and F# major?
One note: where F# major has 7, F# Mixolydian has ♭7 (E). That single half-step is the entire difference in sound — everything else about the two scales is identical.

The seven chords of the parent B major scale, reordered to start from F#: F# (I), Abm (ii), Bb° (iii°), B (IV), Dbm (v), Ebm (vi), E (♭VII). A two-chord vamp between F# and E is the classic way to establish the Mixolydian sound without drifting back to the parent key.
What major scale has the same notes as F# Mixolydian?
B major. F# Mixolydian uses exactly the notes of B major starting from its 5th degree, so every B major shape on the fretboard doubles as a F# Mixolydian shape. The same notes also spell B Ionian, Db Dorian, Eb Phrygian, E Lydian, Ab Aeolian, and Bb Locrian.
How do I practice the F# Mixolydian mode?
Modes live and die by harmonic context — run over a static F# vamp or a drone on F#, not a full progression that pulls back to the parent key. Play the B major shapes you already know, resolve every phrase to F#, and lean on the flat 7th (E). OpenFret's free Studio has a fretboard viewer and metronome for exactly this, and Guitar Quest turns scale practice into a game with real-time pitch detection.
