The E♯ aug Chord Explained
E-sharp augmented is an Augmented chord built from the notes E♯, G♯♯, and B♯♯. Its root is E♯, and its interval number formula is 1–3–♯5, which gives you the interval names root, major third, and augmented fifth. Because the fifth is raised, this chord has a bright but unstable quality that makes it stand out from a regular major chord. It may also be written as E♯ aug, E♯+, or E-sharp augmented triad. If you look at the widget above, you can see and hear how these three notes combine, and you can learn more about chord intervals to understand why the sound feels so tense.

How To Use E♯ aug In Music
Unlike a stable major chord, E-sharp augmented sounds vivid, suspenseful, and slightly dreamlike because its raised fifth pulls the ear forward. That makes it useful as a color chord, a passing chord, or a way to increase tension before a resolution. For example, in a progression you might hear I–III+–vi, or E♯ aug used as a bright transitional sonority between more familiar chords. In another setting, a composer might place it before a dominant harmony, such as I–III+–V–I, where the surrounding chords can make it feel either more dramatic or more elegant. When the chords around it are calm, the augmented sound feels surprising; when the harmony is already tense, it blends in as a natural intensifier. If you want to compare that effect with a related sound, see this guide to augmented chords.
E♯ aug Chord Inversions
Another helpful way to explore this chord is through inversions, which simply means putting a note other than the root in the bass. In root position, E♯ is the lowest note; in first inversion, G♯♯ is the lowest note; and in second inversion, B♯♯ is the lowest note. These inversions keep the same three chord tones but can change the weight and motion of the chord. A root-position E-sharp augmented often sounds the clearest and boldest, while inversions can feel smoother, lighter, or more directional when connecting to nearby chords. Musicians use inversions to improve voice leading, make bass lines more melodic, and control how much tension the chord creates at a given moment.
