A Mixolydian is the mode that makes major sound edgy. It is the major scale with one note lowered — the 7th degree drops by one semitone — and that single change gives it a bluesy gritty quality that pure major simply does not have. It is the sound of classic rock, blues rock, country rock and every guitar riff that feels major but has attitude underneath it. If the major scale is sunshine then Mixolydian is sunshine with a storm on the horizon.

What is A Mixolydian

A Mixolydian is the major scale with one note lowered — the 7th degree. A major has G# as its 7th. A Mixolydian replaces G# with G natural. The result is a scale that sounds major — it has a major third (C#) giving it brightness — but the flat 7th (G natural) adds a tension that pure major cannot provide. That tension is the blues. That tension is rock and roll.

The Notes

A — B — C# — D — E — F# — G — A

Compare to A major: A B C# D E F# G# A

One note different. G natural instead of G#. That is the entire difference between the major scale and the Mixolydian mode.

Open Position

The open position looks almost identical to A major open position — the only difference is G natural (fret 3 low E) instead of G# (fret 4 low E). One fret lower on specific strings.

A Mixolydian notes: A B C# D E F# G

Low E: 0=E  2=F#  3=G
A string: 0=A(R)  2=B  4=C#
D string: 0=D  2=E  4=F#
G string: 0=G  2=A(R)
B string: 0=B  2=C#  4=D? -- fret 4 on B = D# no = Eb
         fret 3 on B = D yes
e string: 0=E  2=F#  3=G

Open Position (R = Root note A)

e |--0--2--3--|    E   F#  G
B |--0--2--3--|    B   C#  D
G |--0--2-----|    G   A(R)
D |--0--2--4--|    D   E   F#
A |--0--2--4--|    A(R) B  C#
E |--0--2--3--|    E   F#  G

Fingers: Open=0  Middle=2  Ring=3  Pinky=4

Compare this to A major open position — the difference is fret 3 on the low E and high e strings (G natural instead of G# at fret 4) and fret 3 on the B string (D instead of nothing there in A major). Play from low E to high e and back down with alternate picking starting at 60 BPM.

5th Position

The 5th position looks almost identical to A major 5th position — the only difference is G natural sitting one fret lower than G# throughout the position.

A Mixolydian notes: A B C# D E F# G

Low E: 5=A(R)  7=B
A string: 4=C#  7=E
D string: 4=F#  5=G  7=A(R)
G string: 4=B   6=C#  7=D
B string: 5=E   7=F#
e string: 5=A(R) 7=B

5th Position (R = Root note A)

e |--5--7--|    A(R)  B
B |--5--7--|    E     F#
G |--4--6--7--|  B   C#  D
D |--4--5--7--|  F#  G   A(R)
A |--4--7--|    C#   E
E |--5--7--|    A(R)  B

Fingers: Index=4  Middle=5  Ring=6  Pinky=7

The flat 7th (G natural) appears at fret 5 on the D string within this position. That note is the entire Mixolydian character — emphasise it in your phrases and the mode announces itself immediately. Play from low E to high e and back down with alternate picking starting at 60 BPM.

Major vs Mixolydian — Side by Side

A Major:      A  B  C#  D  E  F#  G#  A

What Chords Work With A Mixolydian

The key indicator that Mixolydian is the right choice: does the chord progression include a major chord built on the flat 7th? If you are playing in A and a G major chord appears — Mixolydian. If G# appears instead — stay with pure major.

• A7 — the dominant 7th chord. A Mixolydian is the natural scale for any dominant 7th chord
• A — G — D — A — the classic rock Mixolydian vamp. The G chord confirms the flat 7th
• A — G — A — the simplest Mixolydian progression. Used in countless rock riffs
• Blues in A — A7 D7 E7. Mixolydian works beautifully over all three dominant 7th chords

Famous Songs in Mixolydian

• Hey Joe — Jimi Hendrix — the chord progression and guitar lines draw constantly from Mixolydian
• Reeling in the Years — Steely Dan — one of the most celebrated Mixolydian guitar solos ever recorded
• Sweet Home Chicago — Robert Johnson — the original blues Mixolydian. Every great blues player since has drawn from this
• Fire on the Mountain — Grateful Dead — extended Mixolydian jamming at its most fluid

• ☐ Major vs Mixolydian comparison — play A major open position then A Mixolydian open position, hear the flat 7th difference. Repeat 10 times. Target: 3 minutes
• ☐ Open position up and down — low E to high e and back, alternate picking, metronome 60 BPM, 10 clean repetitions. Target: 5 minutes
• ☐ 5th position up and down — low E to high e and back, alternate picking, metronome 60 BPM, 10 clean repetitions. Target: 5 minutes
• ☐ Flat 7th emphasis — improvise in 5th position, land on the G natural note deliberately in every phrase, feel the bluesy tension it creates over a major context. Target: 5 minutes
• ☐ Connect open to 5th position — play up through open position then continue into 5th position without stopping, come back down through both. Target: 5 minutes
• ☐ A7 chord vamp — loop an A7 chord, improvise with A Mixolydian, the dominant 7th chord is the natural home of Mixolydian. Target: 8 minutes
• ☐ A G D A progression — find a backing track using these chords, improvise with A Mixolydian, notice how the G chord confirms the flat 7th. Target: 8 minutes
• ☐ Active listening — listen to Hey Joe by Jimi Hendrix, identify the Mixolydian quality in the chord progression and guitar lines. Target: 5 minutes
