Since its original launch back in 1995, our Original A has become almost the default choice for violists. Offering excellent projection with a broad spectrum of sound colors combined with a long lasting and consistent performance. With the development of our new Virtuoso Viola strings the focus has been upon creating a new offering for viola D, G and C, built upon the firm foundations of our tried and trusted A. The new Virtuoso for viola, available as individual strings or as sets in Medium and Soloist variants, achieves that complementary balance. The Medium set delivers a rich sound texture whilst the Soloist is more focused and brings greater volume to the instrument.
