What is true of it

Am7♭5 is A, C, E♭ and G — 1, b3, b5 and b7 counted from A.

These are also the notes of Cm6/A. Which name is right depends on what is underneath and what came before — the notes alone do not decide.

The easiest of the 5 fingerings below is x0101x: 2 fingers, held at the 1st fret.

2 of them use open strings, which is what makes a shape quiet to change to.

2 strings stay silent.

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.
