When playing G major, we first place the index finger on the second fret of the C string. Next the middle finger is placed at the second fret of the A string, and finally the ring finger goes on the third fret of the E string To keep the fingers from touching the wrong strings, keep the top joints as perpendicular as possible. The index may need a slight bend to accommodate the others. Play each string individually at first to make sure none are being muted.
