– – – – – – –

Summary

F Mixolydian aug contains 7 notes: F, G, A, B♭, C♯, D, E♭. It has 1 sharp: C♯. The step pattern is W–W–H–W+H–H–H–W.

A dominant mode with a raised 5th that adds augmented tension to a Mixolydian framework. It sounds bright and stretched where Mixolydian is normally grounded — like the dominant chord is reaching upward.

Theory

The formula is 1, 2, 3, 4, #5, 6, b7. The #5 creates tension that the b7 wants to resolve, making this an effective scale for dominant chords with augmented quality. It provides a unique color: expansive rather than bluesy.

On the guitar

Take your Mixolydian shapes and raise the 5th one fret. Jazz arrangers use it for dominant chords that need to feel expansive. The #5 works as a tension note that resolves naturally to the 6th or down to the 5th of the target chord.
