Larsen Original Viola A String is made on a solid steel core. It is wound with precision rolled stainless steel flat wire. The C, G and D strings are made with a unique multi-filament nylon core. They use windings of precision rolled silver flat wire for the C and G strings, and aluminium for the D string. Larsen Viola A String has almost become the standard string for the ideal viola set up. It not only has the versatility and good projection, but also can last long and present the consistent performance. They offer two different tensions for these four strings, medium and strong, but A string is also available in soft. The strong tension strings offer more volume and higher resistance to the bow.
