Harmonic Analysis

This progression moves through Gaug7 (Dominant) → C (Tonic).

The V+7–I progression combines the augmented triad with a dominant seventh for maximum harmonic tension before resolving to the tonic. The raised fifth adds an extra chromatic voice leading line on top of the tritone already present in the dominant seventh, creating a double pull toward resolution. This chord is a favorite of jazz and blues players looking for extra color on dominant chords.
