Pro-Arte are D’Addario’s premium classical guitar string sets and are the worlds most popular classical guitar strings. All Pro-Arte 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-Arte basses are wound using silver-plated copper on a multi-filament nylon core for consistent and warm, yet projecting tone. In addition to three traditional nylon treble strings, each Composite set contains an optional monofilament Composite 3rd/G string, which provides greater projection and optimal balance between basses and trebles.
