Pro-Arte synthetic core violin strings have a warm, mellow tone. They are less sensitive to humidity and temperature changes, and break in quickly. Pro-Arte strings are designed at a lower tension in order to maximize bow response, tonal blend and playability. A good choice if a warmer, darker tone than steel strings is desired. Scaled to fit 4/4 size violin with a playing length of 13 inches (328mm), light tension strings allow for easier bow response. Pro-Arte light tension violin strings are available as a single strings only.
