What is a Eaug chord?
An augmented chord stacks the root, major 3rd and raised 5th (#5). Like the diminished chord, both interval gaps are equal — but in this case, two major 3rds. The result is symmetrical and rootless-feeling: any of the three notes could plausibly be the root. Augmented chords feel suspended, dreamy, lifting — never fully resolved.
Notes in the chord: E – G# – C
Intervals: Root, 3, #5 (measured from the root)

When to use a augmented chord
Eaug works as a chromatic lift out of E on the way to A. Use augmented chords as a chromatic step inside a I → I+ → IV motion (e.g. C → Caug → F) — the raised 5th becomes the major 3rd of F, creating smooth voice leading. They appear constantly in jazz, blues turnarounds (the V+ before a I), and any genre wanting that suspended, lifting quality (think Beatles 'Oh Darling' intro, or 60s Bond themes).
Common substitutions for Eaug
- •Augmented 7 (7#5) — adds a flat 7 for a dominant-augmented sound that resolves like V7
- •Whole-tone-derived voicings — augmented + 9 is rooted in the whole-tone scale
