Design and manufactured in the United States, Pro-Arte Short viola strings are held to D’Addario’s strict quality standards. Due to their playability and tonal quality, Pro-Arte viola strings are the string of choice for serious students and amateur violist. The synthetic nylon core produces a warm, dark tone, but it’s the lower tension of the design that provides better playability and a unique tonal blend. Although the Pro-Arte strings are a medium tension, they are designed with a slightly lower tension that maximizes the bow response. The Pro-Arte Short viola strings are sized to fit short-scaled violas, violas with a body length of 13 to 14 inches with a playing length of 13 inches. Not only does the synthetic nylon core provide a warm, mellow tone, it’s also less sensitive to temperature changes and humidity, ensuring your tone is consistent in different conditions. To guarantee your Pro-Arte strings are perfect out of the box, the strings are delivered in corrosive resistant, sealed packaging.
