How to String a Cello: 4 Tips for Stringing a Cello

A cello is a string instrument that serves as the tenor voice in the violin family. Cello players are called cellists, and they produce sound by moving a cello bow over any of the four cello strings that run the length of the instrument from pegbox to tailpiece. Cellists can also produce sounds by plucking the strings with their index fingers, a technique known as pizzicato. Cellos are tuned in fifths. The lowest string is a C string, followed by a G string, D string, and A string. Each of these strings can produce different pitches when a cellist presses down on the instrument's fingerboard, shortening the length of a particular string and raising its pitch. With practice, stringing a cello becomes relatively simple. 1. __Change one string at a time__. Stringed instruments like a cello, violin, and double bass are designed to have constant string tension. By changing just one string at a time, you maintain that tension and keep the instrument aligned and in tune. 2. __Remove the old string__. To remove an old string, start by dropping the tension of the string by facing the front of the instrument and turning the tuning pegs toward you. Once the string is loose enough, you can remove it from the pegbox with your hands. Loosen the fine tuners on the tailpiece, and pull the string out from the bottom. 3. __Note the grooves where the old string was slotted in__. Your cello strings fit into tiny grooves on the instrument's bridge (suspended near the middle of the instrument) and nut (where the fingerboard meets the pegbox at the top of the neck). Some cellists and cello teachers mark these grooves with a soft graphite pencil. These markings won't be visible once the cello is re-strung. 4. __Wipe down the fingerboard__. Changing strings gives you an opportunity to clean your fingerboard, so wipe it with a dry cloth before you put on a new string. 5. __Select the right string__. Cello strings are sold in packs of four. Make sure you choose the correct string by looking at the information printed on the packet. Most cello strings are denoted by the color of the metal ball at the end. (The same is true for violin strings, viola strings, bass strings, and guitar strings.) 6. __Slot the ball end of the string into your tailpiece__. The ball end represents the bottom of your string. It slots into your tailpiece and is held in place by fine tuners. 7. __Thread the string into your peg hole__. Thread a bit of the plain end of the string (the end without a metal ball) into the peg hole on the tuning peg. Modern cello strings are steel strings that can scratch your instrument's wood finish, so avoid leaving too much excess string sticking out of the peg hole. 8. __Tighten the string__. Now it is time to increase the tension of the string. Do this by turning the tuning peg away from you as you face the front of the instrument. As you wind, you'll want to let the string coil around itself to build friction and keep the instrument in tune. 9. __Keep the cello parts aligned__. Tightening strings can cause your tuning peg, bridge, or tailpiece to shift. Keep an eye on all three to ensure they stay aligned and pause tightening if you notice any piece moving out of alignment. 10. __Use a combination of tuning pegs and fine tuners to tune the instrument__. The large tuning pegs make big adjustments to the strings' pitches, while the fine tuners provide the finishing touches. Tuning a cello requires symbiosis between these two components. It takes practice to find the right balance between tuning pegs and fine tuners. 11. __Know that the strings may go out of tune__. Cellos, like all stringed instruments, tend to slip out of tune after being restrung. New strings need to stretch and settle before locking into position. Keep [tuning your cello](https://www.masterclass.com/articles/cello-tuning-guide) and refining the musical instrument until it sounds perfect. A few simple tips can make the cello tuning process easy and efficient. 1. __Use high-quality strings__. Strings from a proven manufacturer are a safe bet for keeping your instrument in tune. No-name strings will suffice for beginners but are not advised for major performances. 2. __Use rosin on your bow__. Whether you're playing on new strings or old strings, use rosin on your cello bow for optimal timbre and intonation. 3. __Tune and retune your cello__. It's normal for cello strings to slip out of tune after you have re-strung the instrument. The strings need to stretch out under tension, and this can take days or even weeks. Keep re-tuning the instrument until it holds the correct pitch, and ideally, time your restringing for several days or weeks before a performance. 4. __Only change one cello string at a time__. This will help keep your bridge and tailpiece in place. A cello left unstrung for long periods of time can fall out of alignment. Luthiers design cellos to have constant tension, so keep them strung up at all times. Become a better musician with the [MasterClass Annual Membership](https://www.masterclass.com).
