Violin strings are essential components of the violin, a string instrument played with a bow. Typically made from materials like gut, steel, or synthetic composites, these strings produce sound when vibrated. Each string is tuned to a specific pitch: G, D, A, and E, from lowest to highest. The choice of string material affects the instrument's tone and playability. Gut strings offer a warm, rich sound but are sensitive to humidity, while steel strings provide a brighter tone and greater durability. Musicians select strings based on their playing style and desired sound quality.
