G♯aug

G♯1B♯3D𝄪♯5

Two major thirds stacked. Symmetrical: every note can be heard as the root.

Written the other way round it is A♭aug — the same twelve keys on a piano, a different piece of notation.

What is true of it

G♯aug is G♯, B♯ and D𝄪 — 1, 3 and #5 counted from G♯.

D𝄪 is a double sharp, and it has to be: every letter from G♯ upwards is used once, so the #5 cannot be written any other way.

The easiest of the 5 fingerings below is 100x: one finger, held at the 1st fret.

2 of them use open strings, which is what makes a shape quiet to change to.

1 string stays silent.

The brass dots are G♯, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
