Ab Mixolydian Mode
Ab–Bb–C–Db–Eb–F–Gb · root also written G#
Ab Mixolydian is the 5th mode of the Db major scale: Ab–Bb–C–Db–Eb–F–Gb. 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 (Gb) in your phrases — landing on it against the root is what makes a line sound Mixolydian instead of plain major.
Because every mode of Db major shares the same seven notes, any Db major fretboard shape works for Ab Mixolydian — what changes is the note you resolve to. Loop a Ab vamp or a backing track that stays on Ab, keep resolving your phrases to Ab, and the Mixolydian color comes through. You'll hear this sound in rock, blues, funk and country.
Ab Mixolydian is mode 5 of Db Major — same seven notes, resolved to Ab 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.
Ab Mixolydian Mode FAQ
What is the Ab Mixolydian mode?
Ab Mixolydian is the 5th mode of the Db major scale — the same seven notes starting from Ab: Ab–Bb–C–Db–Eb–F–Gb. The interval formula is R–2–3–4–5–6–♭7.
What is the difference between Ab Mixolydian and Ab major?

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