D'Addario H514 3/4M C 3/4 Cello Strings

D'Addario Helicore Cello Single C String — 3/4 Scale, Medium Tension

The D'Addario Helicore Cello Single C String is a stranded steel core replacement string designed for 3/4 size cellos with a 700 mm playing length. Built around a multi-stranded steel core rather than a traditional solid gut or synthetic core, this string delivers a clear, warm tone with quick bow response and a smaller string diameter that sits comfortably under the fingers. The C string is tungsten/silver wound to add mass and depth to the lowest voice of the instrument without sacrificing the responsiveness that defines the Helicore line. As a single replacement string, it lets players swap out a worn or broken C without replacing the full set, making it a practical choice for students, advancing players, and working cellists who need to keep their instrument in playing condition. Premium quality materials combined with skilled workmanship produce a string known for excellent pitch stability and longevity.

Who It's For

The Helicore C string is the right choice for cellists who need a reliable single string for a 3/4 size instrument and prefer the responsive feel of a stranded steel core over a traditional gut or solid synthetic core. It suits students working through intermediate repertoire, advancing players exploring more demanding solo and ensemble literature, and working cellists who want a quick bow response and a clear, warm tone that projects well in mixed ensembles. The medium tension is optimized for the majority of players, making it a safe choice when a player is unsure whether to go lighter or heavier. Because it is sold as a single replacement string, it is also ideal for cellists who need to replace a worn or broken C without committing to a full new set, and it pairs naturally with the other Helicore cello strings in the same scale and tension.
