guitar chord
A♭m
The major triad with its third lowered by a half step.
Written the other way round it is G♯m — the same twelve keys on a piano, a different piece of notation.

What is true of it
A♭m is A♭, C♭ and E♭ — 1, b3 and 5 counted from A♭.
On an instrument that cannot reach all 3, the 5 goes first, in that order.
The easiest of the 5 fingerings below is 466444: 3 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.
3 of the 5 need a barre.
Where its notes are on the neck
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.
