About
The Baug7 (B–D♯–F♯♯–A) raises the fifth, replacing the perfect fifth with an augmented fifth. The F♯♯ 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 E. The 3rd, ♭7, and ♯5 are all essential; the ♯5 is what distinguishes this from a plain B7. Common in jazz and blues as a voice-leading tool — the ♯5 often resolves up to the third of the tonic chord. Compared to B7♭5, aug7 feels more expansive and less claustrophobic.
