Understanding the Eb Augmented seventh chord

Names and symbols

Eb7#5 is the chord symbol for Eb Augmented seventh; it is also written Eb+7, Eb7+, Eb7aug, Ebaug7.

7♯5, +7 and aug7 usually all mean this chord: a dominant seventh on an augmented triad. Some books use aug7 for the major seventh on the augmented triad instead, so check which seventh a chart intends.

How it is built

On Eb it is Eb · G · B · Db, stacking 1P · 3M · 5A · 7m. Raising the fifth turns the underlying triad augmented and makes the chord symmetrical in its lower three notes.

How it is used

The raised fifth is a semitone above the natural one, so it leans harder toward the tonic. It is a standard altered dominant, especially heading into a minor chord, and it fits the whole-tone scale exactly.
