Mixolydian Mode
Mixolydian is a major mode with a flat seventh. C Mixolydian changes B to B flat while keeping E as the major third. The same note creates a C7 tonic sonority and the B-flat major flat-VII chord.

How do you build Mixolydian?
Use the formula:
1-2-3-4-5-6-flat 7
C Mixolydian is:
C-D-E-F-G-A-B flat-C
You can derive it by lowering degree 7 of C major or by using F-major notes with C as tonic.
Which note identifies Mixolydian?
B flat forms a minor seventh above C.
It changes Cmaj7 into C7 and removes the B-C leading-tone semitone found in C major.
Play B flat-C and B-C over a C drone. The comparison isolates the changed relationship.
Which chords occur in Mixolydian?
Stack thirds from C Mixolydian:
- I: C major
- ii: Dm
- iii diminished: E diminished
- IV: F major
- v: Gm
- vi: Am
- flat VII: B-flat major
The flat-VII chord contains B flat and frequently moves to F or C in modal progressions.
How do you make C sound like the tonic?
Use C in the bass, return to C major or C7 and end phrases on C.
A C-B flat-F-C loop can support C Mixolydian when C holds the strongest position.
The same notes belong to F major. Avoid making C7 resolve strongly to F if you want C to remain the modal tonic.
Is C7 always a dominant chord?
No. The symbol C7 describes C-E-G-B flat.
In F major, C7 normally functions as V7 and resolves to F. In C Mixolydian or blues, C7 can act as a tonic sonority.
Chord structure and harmonic function are separate. The following progression determines the role.
How is it different from Ionian?
C Ionian uses B natural, G major and B diminished. C Mixolydian uses B flat, Gm and B-flat major.
All other scale notes match.
Compare C-G7-C in Ionian with C-B flat-F-C in Mixolydian. Each progression establishes C through different relationships.
How does it relate to blues?
Both Mixolydian and blues practice use flat 7 over a major tonic.
Blues often also combines minor and major third inflections and dominant-seventh chords on I, IV and V. A Mixolydian scale alone does not describe that complete language.
Use the scale as one pitch resource and learn blues phrasing and harmony separately.
Where is Mixolydian used?
Mixolydian appears in rock, folk, funk, country, jazz and blues-related music.
It works over nonresolving dominant-seventh chords and major-key loops centered on flat VII.
Confirm the tonic and chord function before applying the mode across a progression.
How should you practice it?
Hold C and alternate B with B flat.
Play C-G-C, then C-Gm-C. Add B-flat major and identify the flat-VII chord.
Improvise over C7-B flat while ending phrases on C, E or G.
