D7#5

— About this chord

D7#5 (1–3–♯5–♭7), an augmented dominant 7th, raises the 5th for a restless, whole-tone shimmer that pulls hard toward resolution. Common in jazz turnarounds and blues cadences, it adds harmonic color where a plain D7 would feel too settled, often used as a chromatic passing chord between two diatonic dominants. On guitar it forms a tight open-position shape with the root on the D string, and moves cleanly as a barre chord up the neck. Functionally it heightens dominant tension right before the tonic, a favorite of bebop comping and torch-song accompaniment. Also searched as Ddom7#5, D+7, or D7aug.
