How to Change Classical Guitar Strings

Removing the Old Strings

Use your finger or a string winder to loosen the 6th string from the neck. The 6th string should be the thickest string on your guitar. Attach the winder to the tuning peg and twist it in a circle until the string becomes loose enough to pull off the neck. If you don't have a winder, you can loosen it by hand instead (like you would to tune it down) until you can slide it out of the guitar. If you're in a hurry, grab a pair of scissors and snip all six strings. Be sure to remove the small scrap parts around the bridge when you finish cutting. It's much safer to unwind the strings than to cut them so you won't have pieces of string flying off the guitar.

Untie the string at the bridge and remove it. Once the string is loose enough, you should be able to undo the knot at the bridge by pushing the string back through where the knot was made. Pull the string back out of the hole to remove it completely from the guitar. Safely dispose of the string in a trash can once you remove it from the guitar.

Remove all of the old strings from the guitar. Working your way down the rest of the guitar strings, remove them one by one until there are no old strings left on the guitar. If you prefer to change the strings one at a time, feel free to do this instead. Removing the strings all at once can make it easier when you go to wind the new strings back onto the neck.

Get a new pack of nylon strings. For classical guitars, you'll want to avoid buying steel strings. Instead, you can pick up your favorite pack of nylon strings at a local music shop or off the internet. Never string a classical guitar with steel strings. This will put way too much pressure on the neck, eventually causing it to bend and crack.

Tying the New Strings to the Bridge

Put the new 6th string through the corresponding hole in the bridge. Push it through the hole so that about 4–5 inches (10–13 cm) of string is sticking out towards the base of the guitar. Be sure that you're using the thickest string in your pack as the new 6th string. If one end of your new string has a rough texture while the other end is smooth, use the smooth end to loop through the bridge.

Loop the 6th string around once. You want it going under the other half of the string. It can be helpful to hold the string steady with your thumb and forefinger as you make the loop and eventually go to make the knot.

Tuck the string under the loop and pull to tighten it. As you do this, hold the string down against the soundboard. This is important because if you do not hold the string down, it will be sticking up. This will make it loose and it will probably come undone. Be sure that the tail of the string comes down over the white lip before you tighten it. This will help to ensure that your knot stays tight. The main difference of changing strings on a classical guitar is tying the strings. On a classical guitar, there are no pegs to remove like on a steel string guitar. You have to thread the string through the hole in the bridge, loop it around, and tie it. Make sure the string is secure and string it up on the tuning peg.

Tighten the knot by pulling the string from both sides. You want it as tight as you can get it. Double check that the tail of the string reaches down over the white lip just before you tighten the knot. Tying the knot in the right spot will help to keep your string secure at the bridge. You can check your knot again when you go to attach the string to the neck later on. If it looks loose, redo the knot before you continue.

Repeat with the 5th and 4th strings. The 6th, 5th, and 4th strings (usually E, A and D) are done in the exact same way, but the last three strings are done slightly different. It's mostly the same but you wind it around a few more times.

Attach the 3rd string using the same process, only tuck it under the loop 3 times instead of 1. Because the 3rd, 2nd, and 1st strings (usually G, B and e) are increasingly skinny, they can slip out of the knot that you tie at the bridge much more easily. To safeguard against this slipping, be sure to tuck the strings under their respective loop 2-3 times. Put the string through the bridge as with the 6th, 5th and 4th strings. For the 1st string (the e string), some people like to loop the string around the hole twice for extra protection before tying the knot.

Repeat with the 2nd and 1st strings. These last 3 strings can all be attached in the same way. Use particular care when you attach the 1st string as it is the smallest string and is more prone to slipping out of the knot you tie. Feel free to loop the 1st string through the hole twice before you tuck it under the loop and tighten. If any of the strings come loose, they can hit into the guitar and take out a small chunk of wood. Use extra care when tightening the knots around the bridge to ensure you keep your guitar safe.

Attaching the Strings to the Neck

Turn the tuning peg for the 6th string until the hole is facing up. The string will be easier to work with if you can actually see what you're doing. The new string should be able to run through the hole vertically.

Thread the new 6th string through the hole once. Push the end of the 6th string down through the corresponding hole on the neck. You can push a few inches of string through the hole to make it easier to grip. Although there is another method where the string goes through the hole twice, this method is harder and the first way works just as well.

Run the string back through the gap below the capstan. The capstan is the white plastic part that you wind the string around. You can pull the string back either above or below the capstan depending on your preference.

Pull the 6th string tight until there is about 4 inches (10 cm) of slack in the middle of the neck. You want to leave some slack so that you can tune the guitar without risk of breaking the new string. This would be a good time to double check that the knot you made in the bridge is secure.

Guide the string back through the loop above the capstan. You can do this either once or twice depending on your preference. This should keep the string secure when you wind it up.

Use your finger or a winder to rotate the tuning peg to tighten the string. Hold the loose string and tighten it up the same way you would to tune your guitar. Keep winding until the string is in tune. You can let go of the loose string after a while. Cut off any excess string with a wire cutter. If there is any string sticking out from the head of the guitar, be sure to use a wire cutter to safely remove it. Otherwise, you could accidentally hurt yourself on the string when you go to play your guitar.

Repeat this process for every string. Working in order from the 6th string to the 1st string one at a time can help make it easier to properly attach the new strings to the neck of the guitar. Be careful not to tighten the strings so much that they snap, just like when you tune your guitar normally. After you've attached all of your new strings use a tuner to help you get your guitar back in tune. Alternatively, you can attach the new E string before you remove the old A string, and tune the guitar to itself. To do this, play the E string at the 5th fret and match it to the sound of the A string.
