guitar chord
G♯13
Seven notes in theory and four or five in anyone’s hands: root, third, seventh and thirteenth carry it.
Written the other way round it is A♭13 — the same twelve keys on a piano, a different piece of notation.

What is true of it
G♯13 is G♯, B♯, D♯, F♯, A♯ and E♯ — 1, 3, 5, b7, 9 and 13 counted from G♯.
On an instrument that cannot reach all 6, the 5, 9 and 1 go first, in that order.
The easiest of the 3 fingerings below is 464564: 4 fingers, one of them barring the 4th fret, held at the 4th 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.
It leaves out the 9. 6 strings cannot carry 6 notes, and the 9 is the one this chord can lose without changing what it is.
Where its notes are on the neck
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.
