D'Addario H414 LH Viola Strings

Helicore Viola C String: A Tungsten-Silver Replacement for Full-Size Violas

The Helicore Viola Single C String, Long Scale, Heavy Tension is a single replacement string built around D'Addario's multi-stranded steel core — the same construction used across the entire Helicore viola line. Where many factory-fitted C strings rely on a solid steel core, this stranded core braids multiple steel wires into a flexible cable, giving the string a smaller diameter and noticeably quicker bow response. The C string is wound with tungsten-silver, which adds mass to the lowest string without making it feel stiff under the left hand, and the ball-end fitting makes it a drop-in replacement on any standard viola tailpiece. Designed, engineered and manufactured in the USA at D'Addario's New York production facility, this replacement C is intended for violas measuring 16 inches and over.

Who This String Is For

The Helicore C in heavy tension is the right choice for advancing students, intermediate players and professionals who want a darker, more resistant low C with strong projection in ensemble settings. The heavy tension option suits players who prefer a firmer feel under the bow and a fuller fundamental on the lowest string, particularly in chamber music, orchestral repertoire and traditional classical styles. The stranded steel core and tungsten-silver winding also make it adaptable to alternative styles such as folk, fiddle crossover and contemporary repertoire, where quick bow response and a clear, focused articulation matter. Because it is sold as a single replacement string with a ball end, it works as a drop-in upgrade for any standard viola that takes a long-scale C — no need to replace the full set.
