D'Addario H413 LH Viola Strings

Helicore Viola G String: Clear Tone, Quick Bow Response

The D'Addario Helicore Viola Single G String is a replacement G string built around a multi-stranded steel core, a construction that gives the string both flexibility and a quick bow response. The smaller string diameter helps the string speak immediately under the bow, producing a clear, warm tone that sits well in chamber and orchestral settings. Silver winding on the G string adds focused articulation without dulling the upper register, so the line stays defined even when the player pushes for volume. Helicore strings are known for excellent pitch stability and longevity, and once tuned, the steel core holds pitch reliably through long rehearsals and performances. The ball-end fitting makes installation straightforward on standard viola tailpieces, and the sealed pouch packaging protects the string from corrosion between sessions.

Who It's For

This Long Scale Heavy Tension G string is the right choice for violists who need a powerful, projecting low-end line on a full-size 16"+ viola. Advancing students will appreciate the quick bow response and the way the stranded steel core helps the string speak without excessive bow weight, while intermediate and professional players benefit from the pitch stability during long ensemble work. The string pairs well with traditional classical repertoire as well as alternative styles including fiddle, electric viola, and crossover genres, making it a flexible single-string replacement for any Helicore-equipped viola. Players looking to replace a worn G string on an existing Helicore set will find the same tonal character and response as the original, keeping the set's voice consistent across the full range.
