La Bella Has Over 400 Years of String Making Experience The tradition of string making dates back to the 1640s in Salle, Italy, where the Mari family supplied gut strings to the famous violin builders of Cremona. In 1913, brothers Olinto & Emilio Mari arrived in New York bringing their family craft to the States. Over the years, the brothers shaped the landscape of the string industry with their innovative designs.
