Thomastik-Infeld Spirocore S15 Violin Strings - Full Set (4/4, Medium, Aluminum E)

Thomastik-Infeld Spirocore violin strings are built on a flexible multi-wire spiral rope core. The core has less inertia, so the string keeps vibrating musically for longer, and it works equally well arco or pizzicato. This S15 set comes with an aluminum-wound E string and chrome-wound A, D and G.

• Flexible multi-wire spiral rope core
• Longer period of musical vibration
• Equally effective arco or pizzicato
• Warm sound with excellent tuning stability (per the maker's chart)
