How do you put a string on a violin?

If the string you’re installing has a fine tuner, insert the ball or loop end of the string over the tuner cartridge in the tailpiece, and pull the string toward the bridge. If the string does not have a fine tuner, insert the ball or knotted end of the string through the tailpiece string hole, tug firmly to make sure the knot or ball is securely in the slot, and pull the string toward the bridge. You may need to hold the ball or knot in place with your finger while increasing the tension of the string as you turn the peg. Slightly pull out the peg the string will go in until the peg hole is just inside of the pegbox. Thread the end of the string through the peg hole (let the string slightly protrude), and evenly begin winding it. Push the peg in as you're turning the string to keep the peg from slipping. If your pegs are slipping or are too tight to securely adjust the strings, you may want to purchase peg compound (also called “peg dope”), an inexpensive commercial product. If you don’t have peg compound and need a temporary quick fix for slipping or tight pegs, you may want to try tips some violin teachers use: for sticking pegs, pull the peg partially out, and rub pencil graphite on the sticking part of the peg. For loose pegs, pull the peg partially out, and rub birthday candle wax on the peg to help it stick (some teachers recommend chalk to help pegs stick, but it's abrasive)
