This tutorial is about how to replace a string on a cello. The process is rather simple, and I included a trick that I use to keep the string from slipping off the peg. Replacing one string takes just a few minutes, but replacing all the strings could take 10 or 15 minutes. You should never remove all the strings from the cello at once, and you should use care when removing worn out strings because sometimes they snap. Similarly, you should use caution when tightening new strings because overtightened strings may also snap.

The strings of cellos need to be replaced every year or when they start to wear down. Strings can last longer than a year, but if you play regularly, they do need to be changed once a year. Violins and Violas require more frequent string changes, and this replacement tutorial can also be used to remove and install strings on those instruments.

Step 1: Loosen Pegs

Loosen the pegs by turning them to reduce the tension on the strings. This allows the strings to be removed. There are four pegs on a cello, two for the higher strings and two for the lower strings. In this tutorial, I am replacing a lower string. In the picture, the lower strings are on the left and the higher strings are on the right. The lower strings are also thicker than the higher strings.

Loosen the lower pegs by turning them clockwise or loosen the higher pegs by turning them counter-clockwise. This should cause the string to relax.
<p>Do I have to loosen all the strings to replace one? or will the pressure on the bridge be fine ?</p>
<p>Good simple clear and unpretentious. Everything of importance explained, nothing missed. Put in a way for any sensible kid even ... not perhaps a toddler but any school aged kid, with perhaps minimal adult supervision - so long as they do exactly as advised here - they could not go far wrong . Good that the importance of careful and gradual slackening off (and not all the stings at a time - for one thing the bridge will topple over!) is stressed for removing old string. Good too that the proper use of the 'fine tuners' (I call them 'height adjusters' - which you should have on most modern good quality 'cellos): this is explained well here too.</p><p>Only thing missing, really, is a little appropriate concluding sentence or so ... something like: 'Now you know what to do (and what NOT to do), have pleasure and enjoy playing your instrument. Good luck!'</p><p>Hmmmm!!!</p><p>JEFF, musician and teacher.</p>
Thank you, this helped me a lot!
<p>i play the cello</p>
thank you man!!! ive broken 3 strings already on my cello!! this should really help me out
When I replace my strings, I always take a #2 pencil and rub it thoroughly in the grooves on both the nut and the bridge. It helps the string slide more smoothly and makes for a more consistent tuning experience as the adjustment is more likely to be continuous instead of small jumps if the string gets slightly stuck on the nut or bridge. Pencil graphite is also good for a sticky peg (and rosin dust for a loose peg).
Great job but just another word of advise, you should get a little pencil led on the nut and a little bit less on the bridge so that when you are turning the peg, it goes a bit easier and help prevent fraying from the constant tuning.
