The D'Addario H414 Helicore Long Scale Viola c String is justifiably popular. Helicore strings offer warm, rich sound that's remarkably similar to gut or synthetic core strings. But unlike gut, Helicore strings' all-metal construction renders them impervious to fluctuations in humidity and temperature.

D'Addario Helicore strings have a multi-strand high-carbon steel core that produces flexible response and range. Exotic alloy windings overlay the core and provide extremely quick bow response and outstanding projection. The end result is a versatile viola string with very long playing life that is extremely stable under all playing conditions.
