A♯aug

A♯1C𝄪3E𝄪♯5

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

Written the other way round it is B♭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♯.

C𝄪 and E𝄪 are double sharps, and they have to be: every letter from A♯ upwards is used once, so the 3 cannot be written any other way.

The easiest of the 5 fingerings below is x10332: 4 fingers, held at the 1st fret.

None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.

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.
