The "Infeld Red" set enhances the "darker overtones" on most violins and represents half of the Thomastik-Infeld violin string system (see also Infeld Blue). All 8 strings of this "system" are matched and balanced for playability and tension load so that they may be interchanged to achieve the optimal tonal balance for a given violin, thus minimizing impact to both the player and the instrument. The "Red" set has an "E" that is a gold plated stainless steel, an "A" & "D" that are hydronalium wound over a composite core, and a "G" that is a silver wound over the composite core.
