Larsen Original viola A strings are a go-to option for building a strong viola string set up, offering projection and versatility with extended, consistent performance. They are available in multiple tensions—light, medium and heavy—with medium tension delivering brightness and power, while the heavy tension produces more volume and higher resistance to the bow. Original viola A strings are made with a solid steel core and wound with precision-rolled stainless steel flat wire. They come with a ball end and are designed for instruments 15” to 16-1/2".
