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. The 1/4 scale strings are gauged specifically for 1/4 size violin with a playing length of 10 1/2 inches (265mm).
