C Mixolydian is the major scale with one note changed — the b7, Bb. That single note is what gives the mode its sound: lean on it and the colour is obvious. Leave it out and the melody alone could pass for plain major — then it is the chords underneath that keep the mode.
What is C Mixolydian?
C Mixolydian is the seven notes C D E F G A Bb — the notes of F major started from its 5th degree, C. Same seven notes as the parent, but with C as home, so the intervals and the sound are different.
C Mixolydian vs C major
6 of the seven notes are the same. The difference is one note, and that is the whole character of the mode:
- b7 is Bb in Mixolydian, where C major has 7, B.
Play C major and C Mixolydian back to back over a C chord and listen for Bb — that is the note to lean on.
Chords in C Mixolydian
Stack the mode in thirds and each degree becomes a chord. The home chord is C; the rest are the chords of F major, since the notes are the same — what changes is which one the music rests on. Vamp between C and Bb and the mode is unmistakable.
C Mixolydian on the guitar neck
Because C Mixolydian is F major from its 5th note, its natural fingering is position 5 of the seven three-notes-per-string shapes of F major — the shape whose lowest note is C. Learn that shape with C as home — start and end on it, over a drone on C or the vamp above — and you have the mode under your fingers. Play the same shape with F as home and you hear F major instead. The other six positions are the fingerings for the other six modes of the same key.
How to practice C Mixolydian on guitar
- Loop position 5 of F major at 60 BPM, starting and ending on C so your ear hears C as home rather than F.
- Hold a C chord (or record one) and play the shape over it. Land on Bb on the strong beats — that is the sound of Mixolydian.
- Hear it harmonized in 3rds on the Fretboard: press Play and every note sounds with its partner while the neck lights up.
The tool draws C Mixolydian from its own root: the orange dots are on C and the degrees count from it. The notes are its parent key's, F major; to hear Mixolydian, start and end on C.
