About
The D♭aug7 (D♭–F–A–C♭) raises the fifth, replacing the perfect fifth with an augmented fifth. The A adds a floating, upward-pulling quality to the dominant sound — unlike the inward pull of the ♭5, the ♯5 creates outward tension that resolves naturally when the chord moves to a tonic; here the natural target is G♭. The 3rd, ♭7, and ♯5 are all essential; the ♯5 is what distinguishes this from a plain D♭7. Common in jazz and blues as a voice-leading tool — the ♯5 often resolves up to the third of the tonic chord. Compared to D♭7♭5, aug7 feels more expansive and less claustrophobic.
