E♭ Augmented Triads on Guitar: Every Inversion on Every String Set
A E♭ augmented triad is E♭, G and B (1 3 5). Its three arrangements are each shown on four groups of three strings below, twelve shapes in all; because the notes are evenly spaced, the same shape repeats every four frets.

The notes of E♭+
E♭ augmented is two major thirds stacked, so the outer notes are an augmented fifth (eight frets) apart. Root position puts E♭ at the bottom (E♭, G and B); first inversion puts G at the bottom (G, B and E♭); second inversion puts B at the bottom (B, E♭ and G).
It's the same pitch as D+; this page uses E♭ because it's spelled with fewer sharps or flats.
E♭+ on every string set
On the low E, A and D strings: root position at frets 9–11, first inversion at frets 1–3 and second inversion at frets 5–7.
On the A, D and G strings: root position at frets 4–6, first inversion at frets 8–10 and second inversion at frets 0–2.
On the D, G and B strings: root position at frets 0–1, first inversion at frets 4–5 and second inversion at frets 8–9.
On the G, B and high e strings: root position at frets 7–8, first inversion at frets 0–11 and second inversion at frets 3–4.
Where the inversions sit in the CAGED shapes
The practice pad above shows E♭+'s triads inside each CAGED shape. Use the R, 2, 3 and V switches to see each arrangement:
- Root position: C shape (fret 4), A shape (fret 7), G shape (fret 9) and E shape (fret 12).
- First inversion: C shape (fret 4), G shape (fret 8) and E shape (fret 11).
- Second inversion: C shape (fret 3), A shape (fret 8) and E shape (fret 12).
Where E♭+ appears
E♭+ belongs to 1 key: III+ in C harmonic minor.
It doesn't occur in any major or natural minor key; only the harmonic minor's raised seventh creates it.
None of them is one of the open-string guitar keys (C, G, D, A, E and their relative minors), so E♭+ is more often met in piano-led songs, horn arrangements and with a capo.
Open strings and capo options for E♭+
Two open strings are part of E♭+: the G string (the third) and the B string (the fifth). None of them is the root, so they colour a voicing rather than anchor it.
The E♭+ symmetry
Augmented triads are built from equal major thirds, so they divide the octave into three: E♭+, G+ and B+ contain the same three pitches. That means there are only four different augmented triads, and every shape here moves up four frets to give the next one.
Closely related chords
E♭+ is a major triad with its fifth raised, so it's often a passing chord between E♭ and the chord a fourth up.
