CC Major

Dominant 7th G7 naturally resolves up a 4th to C. It is the tritone between the chord's 3rd and 7th that creates this pull.

Features

Character

Dominant, with 9th and augmented 11th

Characteristic interval

Augmented 11th (#11)

Description

The augmented 11th forms a tritone with the root and avoids the close clash that a perfect 11th creates with the 3rd. The combination of major 3rd, minor 7th, and #11 matches the Lydian dominant scale.
