What the Asus4 chord sounds like

In a sus4 chord a perfect fourth replaces the third. The fourth is 'suspended' and usually resolves down to the third (sus4 → major), a classic move at cadences.

String 2 (B): fret 3, middle finger (D4)
String 3 (G): fret 2, index finger (A3)
String 4 (D): open (D3)
String 5 (A): open (A2)
String 6 (E): fret 5, little finger (A2)

E shape, fret 5, barre at fret 5

String 1 (e): fret 5, index finger (A4)
String 2 (B): fret 5, index finger (E4)
String 3 (G): fret 7, ring finger (D4)
String 4 (D): fret 7, ring finger (A3)
String 5 (A): fret 7, ring finger (E3)
String 6 (E): fret 5, index finger (A2)

For the barre, lay your index finger flat across all the marked strings at fret 5; your other fingers press the higher frets.

The “C, A, G, E and D shapes” are the CAGED system: you slide the shape of the open C, A, G, E or D chord up the neck and your index finger (a barre) takes over the job of the nut. That way the same chord can be played in five places, anywhere on the fretboard.

Tuning: E A D G B E (low to high). String 6 is the thickest, the low E. In the diagram, × means the string is not played, and a circle means an open string.

Playing Asus4 with a capo

A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a Asus4 chord with these open shapes:

Capo: fret 2
shape: Gsus4

Capo: fret 5
shape: Esus4

Capo: fret 7
shape: Dsus4
