Place the guitar on your lap, with the neck facing your left side. Thread a string through the hole in the bridge, leaving a long tail. Pass the tail under and around the string.
Thread the string through the loop and underneath the string. A knot will form that secures the string to the bridge.
Thread the string through the hole in the barrel, which is attached to the tuning peg. Pull the string up through the opening near the barrel.
Take the string's loose end and pass it underneath the string's main part. It should cross underneath and form a knot.
Turn the tuning peg until the knot forms and is tight. Do the same procedure with the other strings.
