D'Addario Pro-Arte 4/4 Size Violin D Strings have a synthetic perlon core that offers the subtle, warm sound and feel of traditional gut strings. Unlike gut strings, though, Pro-Arte strings' inert core is practically unaffected by temperature and humidity.
Precision wound with exotic alloys, D'Addario Pro-Arte violin strings are crafted for long, vibrant life. They are wound and polished on state-of-the-art computer controlled winding machines, then carefully hand-finished and inspected for optimum consistency. Professionals and serious amateurs love the bright timbre and focused response of Pro-Arte violin strings.
