Cello Thomastik-Infeld C String

Thomastik-Infeld Spirocore Cello C String (Tungsten)
Commanding low end, clear articulation, rock-solid stability

Introduction
The Spirocore cello C string is famous for delivering a deep, resonant bass that stays focused and articulate—never woofy—so fast passages remain clean and big orchestral tuttis hit with authority. Its spiral (rope) steel core provides the hallmark Spirocore feel: lively, quick, and consistent day after day.

Detailed characteristics
Using tungsten winding (model S33) over the ultra-flexible rope core, this C string concentrates energy for maximum projection and a tight, centred fundamental with complex upper harmonics. The result is a low string that sounds bright yet weighty, maintaining clarity in any acoustic. Players also value the long life and reliable tuning these strings deliver under professional use.

Playability & feel
Starts are decisive, legato blends smoothly, and the string accepts substantial bow weight without choking—ideal for Romantic repertoire and contemporary techniques alike. Pizzicato is potent and sustaining, and left-hand shifts feel secure across the lowest positions.
