Gut strings are musical strings made from the intestines of animals, typically sheep or cattle. They have been used for centuries in instruments like violins, cellos, and double basses. Gut strings are known for their warm, rich tone and are favored by many classical musicians for their unique sound quality. These strings are more sensitive to humidity and temperature changes compared to synthetic strings, which can affect their tuning stability. While gut strings require more maintenance, they offer a distinct character that many players appreciate. Today, they are often used in historical performance practices and by those seeking an authentic sound in their music.
