Wind the string around the post in a downward spiral, keeping tension with your other hand
Winding a guitar string means wrapping it around the tuning post (also called a tuning peg) so it stays tight and holds its pitch. The string goes from the bridge at the body of the guitar, up the neck, and through a hole in the tuning post. You then turn the post to wrap the string around itself in a spiral. Done right, the string winds neatly, stays in tune longer, and breaks less often. Done wrong, it slips, goes flat quickly, or snaps during tuning.
The process takes about 30 seconds per string once you know the motion. You do not need special tools—just your hands, the tuning key that came with your guitar, and a new string. The goal is three to four neat wraps around the post before the string reaches the top, with each wrap sitting below the one before it.
Key Takeaways
- Insert the string through the tuning post hole, leaving about two inches of slack, then bend it at a right angle to create the first wrap.
- Turn the tuning key so the string spirals downward around the post, with each wrap sitting lower than the last and not overlapping.
- Keep light tension on the string with your other hand while winding so it does not slip or bunch up on the post.
- Stop winding when you have three to four neat wraps, then tune the string up to pitch using the tuning key.
Insert the string and create the first wrap
Start with a fresh string and thread it through the hole in the tuning post. Pull it through until about two inches of string hangs past the post on the side facing the headstock. This slack is what you will wrap around the post.
Hold the string straight up with one hand, then use your other hand to bend it at a right angle, so it points toward the center of the headstock. This bend becomes the first wrap. The string should now form an L-shape, with the long part going down toward the bridge and the short part wrapped once around the post.
Turn the tuning key and spiral the string downward
Insert the tuning key into the post and turn it so the post rotates away from you (on most guitars, this is counterclockwise when looking at the headstock from the front). As the post turns, the string wraps around it. The key is to keep the string under light tension with your free hand so each new wrap sits neatly below the one before it, not on top of it or bunched to one side.
Watch the wraps as they form. Each one should be parallel to the others and sit lower on the post than the previous wrap. If a wrap starts to overlap or climb upward, stop, unwind back to that point, and adjust the tension in your free hand. The wraps should look like a neat spiral staircase, not a tangled mess.
Keep the right number of wraps and avoid overlapping
Most strings need three to four wraps around the post before the string reaches the top of the post and becomes taut. Too few wraps and the string will slip under tension. Too many and the string takes longer to tune and may not wind neatly. On thicker strings (the lower three on a standard guitar), three wraps is usually enough. On thinner strings (the upper three), four wraps gives better grip.
The wraps should never overlap or climb back up the post. If you see this happening, you are either turning the key too fast, not holding enough tension on the string, or the string is not bent at the right angle to start. Slow down, hold the string more firmly, and make sure the first wrap is at a sharp right angle to the post.
Tune the string up to pitch after winding
Once you have the right number of wraps, continue turning the tuning key until the string becomes tight and reaches the correct pitch. Use a tuner (a clip-on tuner or a phone app) to check the pitch as you go. Turn slowly near the target pitch so you do not overshoot and snap the string.
New strings stretch as they are tuned, so the pitch will drop slightly after you finish. Retune it a few times over the next hour. This is normal and does not mean you wound it wrong. After a day or two, the string will hold its pitch much better.
Trim excess string and check the wind
Once the string is in tune, you can trim the excess string hanging past the post. Leave about a quarter-inch so it does not unwind, then use wire cutters or string cutters to snip it. Do not cut it flush to the post—a tiny bit of slack prevents the string from backing out over time.
Look at the finished wind from the side of the headstock. The wraps should form a neat spiral with no overlaps, bunching, or gaps between wraps. If the wind looks messy, unwind it, and try again. A clean wind is not just for looks—it holds tune better and lasts longer.
What to do if the string slips or breaks while winding
If the string slips during winding, the wraps will loosen and the string will drop in pitch. Unwind back to where the slip happened, tighten your grip on the string with your free hand, and wind again more slowly. Slipping usually means you were not holding enough tension or the first wrap was not at a sharp enough angle.
If the string breaks while you are winding, you will hear a snap and feel the tension release. This happens if you turn the key too fast or wind too many wraps. Stop when ready and remove the broken piece. Thread a new string through the post and start over. Breaking during winding is rare if you turn slowly and do not force the string.
Frequently Asked Questions
How tight should I hold the string while winding?
Hold it firmly enough that it does not slip, but not so tight that you strain your hand. Think of the tension you would use to hold a pencil while writing. The string should move with the post as it turns, not slide around it. If you feel it slipping, increase the tension slightly.
Which direction do I turn the tuning key?
On most guitars, turning counterclockwise (when looking at the headstock from the front) winds the string and raises the pitch. Turning clockwise loosens it and lowers the pitch. Check your guitar's tuning direction before you start, since some designs differ. If you turn the wrong way, the string will go slack instead of tight.
Can I wind the string clockwise instead of counterclockwise?
You can, but it is not standard. Winding counterclockwise (the usual direction) keeps the wraps neat and parallel. Winding clockwise can cause the wraps to climb upward and overlap. Stick with the direction your tuning key naturally turns when you want to raise the pitch.
How many wraps should a bass string have?
Bass strings (the thickest ones) usually need only two to three wraps because they are thicker and grip the post better. Thinner strings need three to four wraps for a find hold. If you are unsure, start with three wraps and adjust based on how the string holds tune over the first day.
What if the string keeps going flat after I wind it?
New strings stretch, so some pitch drop is normal in the first few hours. Retune it several times. If it keeps dropping after a day, the wind may be too loose. Unwind it, add one more wrap, and retune. A tighter wind holds pitch better, but do not add so many wraps that they overlap or bunch.
