D'Addario J1014 4/4M C 4/4 Cello Strings

A Warm, Stable C String for Full-Size Student Cellos

The D'Addario Prelude Cello Single C String is a 4/4 scale replacement string designed for full-size cellists who need a warm, dependable low string without buying a whole new set. Built around a solid steel core with a nickel winding and finished with D'Addario's unique damping process, this C string delivers the warmest tone available in the Prelude line, with a focused, rich sound that suits both practice and performance. Because the steel core is unaffected by temperature and humidity changes, the string holds its pitch reliably across rehearsals, recitals, and changing seasons.

Medium tension keeps the C string comfortable under the bow for developing players, while still allowing enough resistance for projection in a small ensemble or solo setting. The ball-end design with solid blue silking makes installation straightforward on any standard cello tailpiece, and the 700 mm playing length matches the standard 4/4 cello scale precisely.

Who This String Is For

The D'Addario Prelude Cello Single C String is the right choice for student and intermediate cellists who need to replace a single worn or broken C string on a 4/4 instrument without committing to a full set. It is well suited to classical repertoire, fiddle styles, and lighter contemporary pieces where a warm, stable low end matters more than maximum brilliance. Because the solid steel core resists humidity and temperature swings, it works equally well in school orchestra programs, home practice rooms, and stage environments.

Beginners will appreciate the medium tension's comfortable bow response and forgiving feel, while advancing students benefit from the pitch stability and consistent tone across long practice sessions. Designed, engineered, and manufactured in D'Addario's New York facilities, this single C string carries the same educator-preferred build quality as the full Prelude cello set.
