Thomastik-Infeld Vienna engineered, paired and perfected the ultra-flexible spiral core and the pioneering tungsten winding in 1957 - making SPIROCORE the revolutionary original and enduring reference standard.
These strings support professional musicians, performing in orchestras or chamber music.
Unlike common steel strings SPIROCOREs flexible core enables stable intonation and unerring focus. They shine with their powerful round sound, saturated depth, excellent brilliance and perfect fifths. With their high-performance capacity, impressive projection and quick response you will find them indispensable. Their outstanding durability is unparalleled and world-famous.
