D'Addario J1012 3/4M D 3/4 Cello Strings

D'Addario Prelude Cello D String — Warm, Stable Tone for 3/4 Size Cellos

The D'Addario Prelude Cello Single D String in 3/4 scale, medium tension, is a replacement string engineered for student cellists and educators who need a reliable D line that holds pitch in changing classroom and rehearsal conditions. Built around a solid steel core and finished with a nickel winding, this single D string delivers the warm, focused tone that has made the Prelude line a long-standing favorite among string teachers. Because it is sold as a single replacement rather than a full set, it is the practical answer when one string breaks or wears out before the others on a 3/4 size cello.

Designed, engineered, and manufactured in D'Addario's New York facilities, the Prelude line uses a unique damping process that gives the string its warm character and excellent bow response. The solid steel core keeps the D string unaffected by temperature and humidity swings, so students do not have to retune every time they move between a chilly hallway and a heated practice room. A solid blue silking at the ball end marks the string as a genuine D'Addario product and makes it easy to identify the correct line when sorting through a school inventory.

Who It's For

Student cellists, school music programs, and rental fleets will find this D string the right choice when they need a dependable replacement on a 3/4 size instrument without committing to a full set. Medium tension suits the majority of cellos and players, making this string a safe default when the original equipment line needs replacing or when stepping up from a generic factory string. Educators appreciate the solid steel core's resistance to humidity and temperature swings, which keeps the string stable in classrooms, rehearsal halls, and home practice rooms. Whether used as a single replacement or to refresh an entire set, this D string gives developing players a warm, even response that supports solid bowing technique and confident intonation across the cello's middle register.
