Go to the full guitar chords tutorial.

The Asus4 chord, an A suspended fourth, is made of A, D and E: a root, a perfect fourth and a perfect fifth. Open strings are part of it, as all four of the shapes listed here use them, from fret 2 to fret 10.

Three of the shapes also involve a barre, so you have a choice between ringing and fretted voicings. Strum with the microphone check on in the player at the top and it shows which strings come through. Asus4 resolves to A major when the D drops to C#, and the A Mixolydian scale supplies all three notes.

A suspended 4th guitar chord is also written as Asus4, Asus or A4.
