Helicore Viola Strings.

Helicore strings are crafted with a multi-stranded steel core, giving them great playability and a clear, warm tone. The smaller string diameter provides quick bow response while the quality of materials and workmanship craft a string with excellent pitch stability and longevity.

D'Addario Helicore strings are justifiably popular; they offer a warm, rich sound that's remarkably similar to gut or synthetic core strings. Unlike gut, however, their 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. The core is overlaid with exotic alloy windings that provide extremely quick bow response and outstanding projection. The end result is a versatile string with very long playing life that is extremely stable under all playing conditions.
