Rooted in generations of D’Addario string making expertise, Pro-Arte’ Nylon is our archetypal classical set. The bass strings are made with a multifilament nylon core and wound with silver-plated copper, for an exceptionally warm and consistent response. Coupled with clear nylon treble strings, which deliver sweet, mellow highs, Pro-Arte’ Nylon gives you the sound and feel that has come to define classical guitar. Normal Tension is our best-selling tension, preferred for the balance of rich tone, comfortable feel, and dynamic projection. 
Pro-Arté, the world's most popular classical strings are D'Addario's premium classical guitar string sets. All Pro-Arté treble strings are sorted by a sophisticated computer-controlled laser machine which performs diameter and tension measurements, ensuring true-sounding, precise trebles in every set. Pro-Arté basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone.
