The Kaplan Vivo Viola C string has a synthetic core with a Tungsten-silver winding. The Synthetic core gives the string a very brilliant but powerful sound and makes it very stable with an excellent bow response.
The Vivo Viola C string differs from The Kaplan Amo in that it is more suited to darker instruments to bring out the sound.
