Amaj7 is A, C♯, E and G♯.
Amaj7 has four notes, and the DADGAD guitar has six strings to play them on. The rest of this page shows how a hand fits one to the other.
On the staff
On a treble staff, Amaj7 is written A, C♯, E and G♯.
The staff shows the notes one after the other, then together. Written this way the chord is in close position, which means each note sits as near to the one below it as the spelling allows. A guitar almost never plays a chord in close position.
Amaj7 under a hand
Strummed from the lowest string to the highest, this grip sounds C♯, G♯, E, G♯, A and C♯, which are the degrees 3 7 5 7 1 3 rather than the 1 3 5 7 of the written chord. The lowest note is the 3 rather than the root, so this grip is in first inversion, written Amaj7/C♯. It has the same notes as the root-position grip, but with C♯ in the bass it sounds different. With C♯ in the bass and six strings sounding four notes, the 3 and 7 appear more than once.

The lowest note is the 7 rather than the root, so this grip is in third inversion, written Amaj7/G♯. It has the same notes as the root-position grip, but with G♯ in the bass it sounds different. With G♯ in the bass and six strings sounding four notes, the 5 and 7 appear more than once.
Two shapes for Amaj7 on DADGAD guitar: Amaj7/C♯ and Amaj7/G♯.
Amaj7 has no root-position shape on DADGAD guitar, because there is no way to put the root below the other notes and still reach the whole chord. A chord with a note other than the root at the bottom is called an inversion, and every way of playing Amaj7 here is one. That comes from how this instrument is tuned, not from the chord itself. When a grip sounds a note more than once, the fretting hand decides which note that is, not the harmony.
A, C♯, E and G♯ on the whole neck
This diagram marks every A, C♯, E and G♯ on the first fifteen frets of the DADGAD guitar.
Every grip above is a handful of the notes on this diagram, and none of them uses a note that is not shown here.
Where Amaj7 comes from
Amaj7 is a chord of E major, F♯ natural minor and A major.
A chord does not belong to a single key. Each major or natural minor key listed here contains every note of Amaj7, which is why the same grip turns up in songs that otherwise have little in common.
