Thomastik-Infeld Thomastik Spirocore Medium Gauge Single Violin String 4-4-E -S9-

S9 E-String HI-tech, top grade, spiral steel core strings Spiro core strings are a further technical development of our Sail series and have a flexible spiral steel core. This core has greater elasticity than that of conventional strings, which means less inertia and a higher propensity to musical vibration. The sound is full and homogenous, balanced and voluminous. The string has been calibrated to satisfy the express wish of many artists for an equally effective Arco and pizzicato. Spirocore's hi-tech core makes for effortless fingering, responsive bowing, stable tuning and a very long string life. With Spiro core the steel string's technical possibilities have been developed to their maximum.
