The A sharp Major 7 chord (also written as A# Maj 7) contains the notes A#, Cx (C double sharp), E# and Gx (G double sharp). It is produced by taking the root, 3rd, 5th and 7th of the A# Major scale. It is essentially an A# flat Major chord, with the 7th note of the Major scale added.
A# Major 7 is most commonly played with the root note on the 2nd fret of the 6th string (second shape below).
The Major 7 chord in general is considered a kind of default chord, as it contains no altered notes of the Major scale (1, 3, 5, 7). It can also be used as a starting point, when figuring out other chords that have the same root note. For example, the A# minor 7 chord can be produced by lowering the 3rd and 7th of the A# Major 7 chord.
