F♯aug

F♯1A♯3C𝄪♯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

F♯aug is F♯, A♯ and C𝄪 — 1, 3 and #5 counted from F♯.

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

The easiest of the 3 fingerings below is x665: 3 fingers, held at the 5th 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 F♯, 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.
