The Mixolydian scale is a variant of the natural major scale with a single change: the seventh degree is lowered a half step (UK: semitone). That one alteration creates the characteristic modal sound of the fifth mode of the major scale, which is very common in jazz, blues, rock and folk music.
It is also called the Mixolydian mode and in major-scale teaching it is the major scale with a lowered 7th (♭7). It is the 5th of the Greek modes. Its pattern of whole steps (W) and half steps (H) is W-W-H-W-W-H-W. Because it shares its notes with the dominant seventh chord, it has the "dominant" color that is so typical of blues and rock.
In the Spanish conservatory scheme this scale is one of four "types" of major scale (natural, Mixolydian, "mixed main" = harmonic major, and "mixed secondary" = melodic major). Outside that scheme it is simply the Mixolydian scale.
Start from the natural major scale:
Lower the seventh degree by a half step and you get the Mixolydian scale:
In the examples, the lowered note is shown in red to make it easy to spot. You do not need to mark it in exercises.
The scales are shown in two ways: with the accidentals written inside the scale, and with a key signature. Both are equivalent.
Interval pattern
The pattern of whole steps and half steps of the Mixolydian scale is W–W–H–W–W–H–W. It is identical to the natural major scale except at the seventh degree. In the major scale the step from degree 7 up to the octave is a diatonic half step (the leading tone). In the Mixolydian scale it is a whole step, so the seventh is a subtonic (a "flat seventh") and the scale has no leading tone.
| Degree | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Step from previous note | — | W | W | H | W | W | H | W |
| C Mixolydian | C | D | E | F | G | A | B♭ | C |
| C major | C | D | E | F | G | A | B | C |
Thanks to this pattern, the Mixolydian scale is the same as the fifth mode of a major scale: C Mixolydian has the same notes as F major, starting from its fifth degree.
