Gaug Chord on Guitar
G Augmented is G, B, D# — the 1-3-#5 pattern of a augmented chord. Here is the shape, the audio, and what usually goes wrong.
There is no open Gaug 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 (3rd fret)
Barre at fret 3 — 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 (3rd fret) — barred at fret 3.
Listening: each shape above has its own play button, and each one plays the notes that shape actually produces — not a generic triad.

Gaug on Guitar — questions people ask
What is the easiest way to play Gaug on guitar?
“E Shape Barre (3rd fret)” — which we rate advanced — is the easiest Gaug shape on guitar. Barre at fret 3 — harder to hold than an open shape, but movable: slide it and you have every other augmented chord. There is no open Gaug on guitar, so a barre is unavoidable; this is the least demanding one.
What notes are in the G Augmented chord?
G Augmented is G, B, D# — the 1-3-#5 interval pattern of a augmented chord. Every voicing on this page uses those notes and nothing else; they just appear in a different order and octave.
What can I play instead of Gaug?
The nearest stand-ins on guitar that keep the same root are G5, Gsus4, Gsus2. They keep the root and the fifth and only change what sits in the middle, so most songs still work — but check the swap against the melody, because the note you removed may be the one the tune is singing.
Can I play Gaug on other instruments?
Yes. Gaug is the same set of notes everywhere; only the fingering changes. This site has diagrams and audio for it on piano, ukulele, bass, mandolin, banjo.
