With an innovational design that reflects six generations of expert craftsmanship, Pirastro’s Tonica viola strings provide players a soft, but fully rounded sound. The synthetic nylon core creates a wide tonal palette that players can easily manipulate. Although the nylon core strings produce a deeply rich sound, comparable to gut strings, Tonica strings provide easier bowing response and playability than gut core strings. Tonica viola strings are also easily tuned and maintain their pitch. Along with the Tonica strings’ synthetic nylon core, the A and D string is wound in aluminum, and the G and C strings are wound in silver. The winding enhances the viola strings’ resonance and increases its projection. The C string is also available in a tungsten and silver winding variation for an even more powerful projection. Unlike gut core strings, Tonica strings are impervious to the effects of drastic climate changes and humidity.
