A Mixolydian Scale: Notes, Chords, and How to Play It

A Mixolydian is the bread and butter of blues-rock guitar. Built on the 5th degree of D major, it shares those same notes but treats A as home. The open A string on guitar provides a natural drone, and the dominant 7th tonic (A7) is one of the most played chords in blues history. If you have ever bent a note over an A7 shuffle, you have been playing in A Mixolydian.

What Makes Mixolydian Different from Major?

The Mixolydian mode is almost identical to the major scale. The only difference is the flatted seventh degree — the note one whole step below the root instead of a half step. In A Mixolydian, this means G natural rather than G♯.

This ♭7 removes the leading tone — that half-step pull from the 7th degree up to the root that gives the major scale its strong sense of resolution. Without it, Mixolydian sounds more open, relaxed, and bluesy. The tonic chord is naturally a dominant 7th (A7) rather than a major 7th, which is exactly why Mixolydian is the go-to scale for playing over dominant 7th chords in jazz and blues.

Notes of the A Mixolydian Scale

The A Mixolydian scale contains seven notes:

A – B – C♯ – D – E – F♯ – G

These are the same notes as D major, but starting and resolving on A. The scale follows the Mixolydian interval pattern — W – W – H – W – W – H – W.

The half steps fall between C♯–D (degrees 3–4) and F♯–G (degrees 6–7). Compare this to A major, where the half steps fall between C♯–D and G♯–A. The only change is that final interval: G replaces G♯.

Parent Major Scale

A Mixolydian is the 5th mode of D major. This means it uses exactly the same notes as D major but with A as the tonal centre.

To find the parent major scale for any Mixolydian mode, go down a perfect 5th (or up a perfect 4th) from the root.

Comparison with A Major

Since Mixolydian differs from major by just one note, a direct comparison is the clearest way to understand the mode:

That single change — G♯ to G — transforms the sound. The major scale pulls strongly towards resolution; the Mixolydian mode sits comfortably without that tension.

A Mixolydian on Piano

A Mixolydian has two sharps: C♯ and F♯. This is the same key signature as D major, so if you are comfortable with D major on piano, you already know where to put your fingers — just start on A.

Right hand fingering (ascending): 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 (thumb crosses under after C♯, then fingers walk up to A)

Left hand fingering (ascending): 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 (after the thumb plays E, the third finger crosses over to F♯)

Hold an A7 chord with the left hand while running the scale with the right to reinforce the Mixolydian sound and train your ear to hear A as home.

A Mixolydian on Guitar

A Mixolydian is one of the most comfortable keys on guitar. The open A string provides a natural root, and the scale sits nicely in open position.

Open position (low to high):

This covers one octave from A on the 5th string to A on the 3rd string. The open G string is a scale tone (the ♭7), making it easy to accent the defining Mixolydian interval.

Diatonic Chords in A Mixolydian

Stacking thirds on each scale degree produces these seven triads:

The ♭VII chord (G major in A Mixolydian) is the characteristic chord of the mode. The movement from A to G — a whole-step drop — is the quintessential Mixolydian sound heard in classic rock and blues.

Seventh Chords

Adding a fourth note to each triad creates seventh chords:

The tonic chord is a dominant 7th (A7) — perhaps the most important chord in all of blues music. A7 is the sound of the 12-bar blues, and A Mixolydian is the scale that fits it perfectly.

Common Chord Progressions in A Mixolydian

Mixolydian progressions tend to be simpler and more riff-driven than major key progressions.

The I – ♭VII movement (A – G) is immediately recognisable — it powers riffs and turnarounds across rock, country, and blues.

Songs That Use A Mixolydian

A Mixolydian appears across many genres:

• “Sunshine of Your Love” — Cream
• “Tush” — ZZ Top
• “Franklin’s Tower” — Grateful Dead
• “Tube Snake Boogie” — ZZ Top
• “Rock and Roll” — Led Zeppelin (A7 riff)
• “Pride and Joy” — Stevie Ray Vaughan

Listen for the ♭7 note (G natural) in the melody or the ♭VII chord (G major) in the harmony — these are the tell-tale signs of Mixolydian rather than plain major.

Related Scales and Modes

A Mixolydian belongs to the D major family. All seven modes share the same notes:

Practice Tips

Emphasise the ♭7. Play A major ascending, then play A Mixolydian. The only difference is G vs G♯ — train your ear to hear that subtle but powerful shift.

Vamp on I – ♭VII. Alternate between A and G chords while improvising with the scale. This locks in the Mixolydian sound.

Play a 12-bar blues. A7 – D7 – A7 – A7 – D7 – D7 – A7 – A7 – E7 – D7 – A7 – E7. Use A Mixolydian over the A7 sections — it fits perfectly.

Use the open A string. On guitar, let the open A ring as a drone while playing scale patterns on the higher strings. This anchors the Mixolydian tonality.

Compare with A major. Play a phrase in A major, then repeat it with G natural instead of G♯. Hear how the character shifts from bright resolution to bluesy ease.
