A Major Sixth Sharp Eleventh Added Guitar Chord Fingering
An A6(#11) chord, also called A sixth sharp eleventh, is made of A, C#, E, F# and D#. The D# is the raised fourth of the A scale, placed an octave above the root, and it gives the chord its name.
Because the chord already contains the sharp eleventh, the A Lydian scale, with its raised fourth, is the right scale to solo with. The D# sits a half step below the fifth, E, so the top of the chord carries a tight interval. When you add the chord to a progression, smoother chord changes will help.
A 6th with sharp 11th guitar chord is also written as A6(#11), A6#11, Amaj6(#11) or A6(+11).
