What is true of it

Amaj9 is A, C♯, E, G♯ and B — 1, 3, 5, 7 and 9 counted from A.

On an instrument that cannot reach all 5, the 5 and 1 go first, in that order.

The easiest of the 5 fingerings below is 546400: 4 fingers, 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.

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.
