Prelude violin strings are solid steel strings, insensitive to variations in temperature and humidity, and have excellent bow response. Prelude strings have the warmest sound available, thanks to a strong, cost-effective steel string design. Prelude is the educator's preferred choice for student strings because of their unique blend of warm tone, economical pricing, and durability. Suitable for a 4/4 size violin with a playing length of 13 inches (328 mm), the medium tension strings are optimized for the needs of a majority of musicians.
