Extremely popular with a wide variety of players, D’Addario’s Helicore violin strings are preferred for their durability and excellent tone. The Helicore Medium violin strings feature a multi-stranded, steel core and a narrower diameter providing easy bowing response, a richer, fuller and warmer tone than solid steel core strings. They provide excellent projection and maintain exceptional tuning stability. Helicore Medium gauge strings provide outstanding balance of brilliance and warmth, and are available with multiple high quality winding options to accommodate playing style, preference and instrument sound. You can choose from sets with an unwound, tin-plated steel E or an aluminum wound on steel core E. Single strings from both sets are available, including both types of E strings, A strings of either aluminum or titanium wound on a stranded steel core, and a low, single C string. You will also find a medium tension, five string set with a plain E string. Manufactured in the United States, Helicore strings are held to D’Addario’s high quality standards.
