Why it sounds like that
E augmented major 7th is built as 1–3–♯5–7, with major thirds between E and G♯, and G♯ and B♯. The raised fifth B♯ (enharmonically C) gives the chord its augmented tension, while the major seventh D♯ adds brightness. Compare E major 7th, which has a perfect fifth B.
What goes wrong with E augmented major 7th?
- Letting the open E string overpower the fretted G♯ on the 3rd string.
- Fretting the 1st string too hard, causing it to go sharp.
When to use it
E augmented major 7th works as a passing chord between E major and A♭ major, or as a substitute for E major 7th in jazz. Its open-string resonance suits folk-influenced jazz and atmospheric ballads.
Changing to and from E augmented major 7th
- Move to E major 7th by lifting the middle finger and fretting the 1st string at the 2nd fret.
Which voicing to use
The open E inversion places the root in the bass, giving a solid, grounded sound. The B♯ inversion puts the augmented fifth in the bass, creating a tense, leading tone. The D♯ inversion places the major seventh in the bass, which darkens the chord.
