D'Addario J914 MM Viola Strings

D'Addario Prelude Viola C String — A Reliable Replacement for Medium-Scale Violas

The D'Addario Prelude Viola Single C String, Medium Scale, Medium Tension is a standalone replacement string engineered for violists who already use the Prelude series and need to swap out a single C string without buying a full set. Built on a solid steel core with a nickel-wound wrap and a ball-end fitting, this string delivers the warm tone and stable pitch that have made Prelude the educator's preferred choice for student strings. The medium-scale specification targets violas with a body length of 381–406 mm (15"–16"), making it the right fit for the most common student and intermediate viola sizes. Unlike synthetic-core strings that can feel stiff under the bow, the solid steel core provides excellent bow response and remains unaffected by temperature and humidity changes during practice, lessons, and performances. Packaged in a sealed pouch that protects against corrosion, the string arrives ready to install and settles into playing pitch quickly after fitting.

Who It's For — Students, Educators, and Replacement String Buyers

The D'Addario Prelude Viola Single C String is the right choice for students, intermediate players, and educators who need a single replacement C string for a medium-scale viola without purchasing an entire set. It suits players working through classical repertoire, fiddle tunes, jazz arrangements, and alternative styles who want a warm, dependable tone at an accessible price point. School music programs, rental fleets, and private studios benefit from the string's resistance to humidity and temperature changes, which keeps instruments stable between lessons and performances. Players who already use Prelude strings on the A, D, and G positions will find this single C string matches the series' tonal character and bow response for a consistent voice across the instrument. The ball-end fitting and medium tension also make it a practical choice for younger players who change strings frequently and need a quick, secure installation. Because the C string is the lowest and thickest on the viola, replacing it individually is often more economical than replacing the full set when only one string has worn out or broken.
