Go to the full guitar chords tutorial.
Built on A, the A7(#11) chord (A seventh sharp eleven) combines a root, a major third, a perfect fifth, a minor seventh and a sharp eleventh, which gives A, C#, E, G and D#. It is a dominant seventh with a raised eleventh (D#), a tritone above the root, which lifts the sound into the bright lydian dominant colour.
This page has one voicing: it is not a barre shape and it uses no open string. The A Lydian Dominant scale, the fourth mode of the melodic minor scale, lines up with A7(#11), because it contains all five chord tones.
Pick a tempo for the drum loop in the tool at the top of the page and repeat the chord in time.
A 7th with sharp 11th guitar chord is also written as A7(#11), A7#11 or A7+11.
