F mixolydian b6

The mixolydian b6 scale, the fifth mode of the melodic minor scale, is a dominant scale whose top half turns minor: natural 3rd, flat 6th, flat 7th. The b6 gives the plain mixolydian sound a bittersweet, almost cinematic shading. It is the natural choice over a V7 resolving to a minor chord, spelling the coming darkness in advance.

it consists of these notes and degrees:

tip
  • Use F mixolydian b6 (Db) over a V7 resolving to a minor chord: the flat 6th (Db) previews the minor destination inside the dominant bar.
  • It is the fifth mode of melodic minor; over a static dominant vamp, alternate it with plain mixolydian and let the 6th tell the story.
  • Lean on b6 (Db) falling to V, the scale's built-in sigh, especially over the chord's own 5th in the bass.
  • Try it over the IV7 chord in a minor blues in the key a 4th below F; the borrowed darkness fits perfectly.

How to play F mixolydian b6 on guitar

Lowest root sits at fret 1 on the low E, giving the E-shape barre a home right at the nut. Open A and open G are the key's only open strings, sitting on the third and the second, which means neither can hold a pedal. Capo fret 1 and E fingerings apply. Bbm and Cm take iv and v, and Dbaug supplies the bVI+.
