D'Addario J913 MM Viola Strings

D'Addario Prelude Viola Single G String — Warm Tone and Lasting Durability for Student Violas

The D'Addario Prelude Viola Single G String, Medium Scale, Medium Tension is a single replacement string designed for medium-scale violas in the 15"–16" body range. Built on a solid steel core with a ball-end construction, this G string delivers the warmest tone available in an affordable steel-core design — a key reason educators and school programs reach for Prelude when outfitting student instruments. The solid steel core contains a pitch-stable alloy that holds tuning reliably through daily classroom use, practice sessions, and ensemble rehearsals.

Unlike gut or synthetic-core strings that react to climate, this steel-core G string stays unaffected by temperature and humidity changes, making it a dependable choice for players who move between rehearsal rooms, performance halls, and home practice. A unique damping process used in Prelude strings gives the G string a warm, focused tone with excellent bow response, so beginners can develop a clean, articulate sound without fighting an overly bright or harsh string. Designed, engineered, and manufactured in the USA at D'Addario's New York production facility, this single string carries the same build quality as the world's best-selling steel-core orchestral line.

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

The D'Addario Prelude Viola Single G String, Medium Scale, Medium Tension is the right choice for student violists, school orchestra programs, and private studio teachers who need a reliable replacement G string for medium-scale violas. It works equally well for beginners working through their first method books, intermediate players preparing for ensemble auditions, and educators who keep a stock of single replacement strings on hand for quick repairs between lessons.

Because the G string carries much of the viola's lower register weight, choosing a steel-core design like Prelude gives developing players a stable, durable foundation that holds up under frequent bow changes and shifting positions. Medium tension offers a comfortable feel under the left hand without requiring excessive bow weight to produce a full sound. Versatile enough for classical repertoire, fiddle styles, jazz, and alternative genres, this single G string is a practical, value-priced solution whenever a worn or broken string needs replacing on a medium-scale viola.
