D'Addario J913 LM Viola Strings

Warm, Stable Tone for Student and Advancing Violists

The D'Addario Prelude Viola Single G String is a medium-tension replacement string engineered for long-scale violas with body lengths of 16–16.5 inches and a 380 mm playing length. Designed as part of D'Addario's educator-preferred Prelude line, this single G string offers the warmest sound available in an affordable solid steel core design. It is the right choice for student violists, school orchestra programs, and advancing players who need a reliable, pitch-stable string that responds consistently from lesson to lesson. The solid steel core with a unique damping process gives the string its warm character and excellent bow response, while the ball-end fitting makes installation straightforward on any standard viola. Packaged in sealed pouches that protect against the elements causing corrosion, the string arrives ready to install and stays stable through the humidity and temperature shifts that often challenge student instruments.
