A♭aug Chord on Guitar
Ab Augmented is Ab, C, E — the 1-3-#5 pattern of a augmented chord. Here is the shape, the audio, and what usually goes wrong.
There is no open Abaug on guitar — the single shape below is a barre, which is exactly why this chord trips people up. Take it slowly and check every string.
Start here — E Shape Barre (4th fret)
Barre at fret 4 — harder to hold than an open shape, but movable: slide it and you have every other augmented chord.
What beginners get wrong
Moving in and out of it
The shape above: E Shape Barre (4th fret) — barred at fret 4.
Listening: each shape above has its own play button, and each one plays the notes that shape actually produces — not a generic triad.
