Harmonic Function

The E augmented chord commonly functions as the mediant (iii) in C major or dominant (V) in A major. Its harmonic role varies by key — in major keys it provides stable harmonic grounding.

The augmented triad consists of two stacked major thirds, creating a symmetrical, ambiguous chord. Its raised fifth gives it a tense, unresolved quality that pulls toward resolution. The E Augmented Triad specifically contains 3 notes: E, G♯, C (formula: 1-3-♯5). On guitar, E-rooted chords use both the low and high open E strings, creating a powerful full-register voicing that spans all six strings. Hard rock, metal, and punk lean heavily on E-rooted chords and power chords because the low E string provides maximum sonic impact for distorted tones.
