D'Addario H315 4/4H C Violin Strings

Helicore Violin Low C String — Stranded Steel Core for 4/4 Scale

The D'Addario Helicore Violin Single Low C String is a precision-engineered replacement string for 4/4 scale violins, built around D'Addario's groundbreaking stranded steel core technology. Unlike traditional solid-core strings, this Low C uses braided steel wires forming a cable core that blends strength with flexibility, producing a clear, warm tone with quick bow response. The tungsten/silver winding on the C string adds mass and projection without sacrificing the responsive feel that defines the Helicore line. Heavy tension construction gives this string greater volume potential and projection compared to medium tension alternatives, making it well suited to players who need to cut through in ensemble settings or carry a room in solo performance. Packaged in uniquely-designed sealed pouches, the string is protected from the elements that cause corrosion, ensuring it arrives ready to install and play.

Who It's For

The Helicore Low C String in heavy tension is the right choice for violinists who need a reliable replacement C string with strong projection and clear articulation. It works exceptionally well for advancing students, intermediate players, and professionals who play 5-string violins or fiddles, where the Low C extension must hold its own against the higher strings without sounding thin or loose. The stranded steel core construction makes this string adaptable to cross-tuning and a wide range of musical styles, from classical repertoire to traditional fiddle music and contemporary genres. Players who prefer a warmer, more complex tone with excellent bow response will appreciate the balance of clarity and depth that the stranded core design provides. The heavy tension option is particularly suited to players with a firmer bowing technique who want maximum volume and projection from their instrument, and it pairs well with the rest of the Helicore violin string line for a consistent feel across all four strings.
