Designed with quick bow response and ease of use in mind, D?Addario?s Prelude violin strings are the educator?s preferred choice for student strings. Due to their unique blend of warm tone, affordability and durability, they are ideal for the brand-new violinist picking up a bow for the first time, and the more experienced student in the high school string orchestra. Available in both full and fractional sizes, the Prelude line has an option for any age student. The strings have clear markings to teach students how to string their instrument and are easy to put on and tune. D?Addario leverages centuries of string-making experience and advanced computer-controlled winding technology to bring you the most durable, consistent and long-lasting strings. With its solid steel construction and uniquely-designed sealed pouches, Prelude strings have an unparalleled protection from the elements that cause corrosion. Unaffected by temperature and humidity changes, the strings wear well and can stand up to a student player?s usage. All D'Addario strings are designed, engineered and manufactured in the USA to the most stringent quality controls in the industry. Scaled to fit a 4/4 size violin with a playing length of 13 inches (328mm), these medium tension strings are optimized to the needs of a majority of players. Since 1905, D?Addario has been providing artists and players with the tools they need to perform their magic.
