Am9 (A minor ninth) takes A, C, E, G and B, so it is Am7 with a ninth added. Ten voicings are listed, seven of them using open strings and three using a barre.

The C, E, G and B above the root form a Cmaj7 chord. That relationship is worth knowing in jazz progressions with minor chords, where a minor ninth can take the place of a plain minor seventh. The A minor scale contains all five notes.

Strum Am9 in front of the microphone and the player at the top tells you which strings are ringing.

A minor 9th guitar chord is also written as Am9, Amin9 or A-9.
