A♭aug

A♭1C3E♯5

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

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

What is true of it

A♭aug is A♭, C and E — 1, 3 and #5 counted from A♭.

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 A♭, 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.
