Short answer

Dominant seventh sharp five chords sound restless and a little exotic. Raising the fifth of a dominant seventh trades its usual bluesy pull for a sharper, whole-tone edge, a colour jazz and gospel players reach for right before a cadence.

How to use the D♭7♯5 chord

The D♭7♯5 chord is built from a root, a major third, an augmented fifth and a minor seventh. Start at the root D♭ and stack the intervals to get the whole chord: D♭, F, A and C♭. The same formula gives you the chord in any other key.

Dominant seventh sharp five chords turn up in jazz and gospel as an altered V7 resolving to the tonic, especially where the melody climbs through the raised fifth. They are a common sound in turnarounds right before landing back on I.

How D♭7♯5 differs from similar chords

D♭7♯5 is D♭7 with the fifth raised by a half step, and that raised fifth is the only difference. Seen from the other side, it is D♭+ with a minor seventh added. All four of its notes belong to the whole-tone scale, which gives it a floating, restless pull.

Where D♭7♯5 is used
