A better name for it would be AminMaj7. It is the "harmonic" minor chord.

----------- ( E, 5th)
---1------- ( C, b3rd)
---1------- ( G#, maj7th)
---2------- ( E, 5th )
---0------- ( A, root )
---x------- ( mute or don't play, but could be played open E for another 5th)

(that's one way I would play it )

I hate doing this.......

I must say that this is not correct. The Amin(Maj 7) chord does not contain both thirds. It is a minor triad with a Major 7th interval stacked on top. ACEG# is the correct spelling and your grip is correct but this is different than the original post..... Amaj7b3, which is written incorrectly.

A chords extension never uses the number 3. I could be written as Amaj7#9, in which case the chord would be spelled; AC#EG#C.

Sorry..... I must keep things exact. :o
