String tension refers to the amount of force exerted on a string, such as those found on musical instruments like guitars or violins. This tension affects the pitch and tone produced when the string is played. Higher tension typically results in a higher pitch, while lower tension leads to a lower pitch. In addition to affecting sound, string tension also influences the playability of an instrument. Musicians often adjust string tension to achieve their desired sound and feel. Factors such as string material, thickness, and instrument design can all impact the overall tension and performance of the strings.
