To play a Esus2 chord, take your index finger and place it over the second fret of the E and A strings. Position them so when you press down both strings sound clear with no bad or muted sound, once you have that put the ring finger on the fourth fret of the G string. Finally, the pinky is used on the fourth fret of the C string. You will need to move the ring finger back a little to make space for the pinky, adjust until they are not interfering with each other. The stretch is not easy and even puts more pressure on your index finger. It isn’t horribly difficult, but the awkward feel of the hand will take some getting used to.
