professional reliability. Individual G and C Spirocore Tungsten strings for 4/4 cello. Flexible spiral rope steel core with tungsten outer winding. These are lower-string replacements only, commonly paired with another brand's A and D for a custom hybrid setup. About Spirocore Tungsten The iconic lower-string choice for cellists who want maximum projection. Thomastik-Infeld Spirocore Tungsten G and C Set is one of the most recognisable lower-string options in professional cello playing. The flexible spiral rope steel core and tungsten outer winding produce a tone that is brilliant, focused, and powerful, yet still musical and warm enough to blend in ensemble contexts. The Spirocore G and C are frequently used as part of a hybrid setup: many players pair them with another brand's A and D to achieve a custom tonal balance, combining Spirocore's bright, projecting lower register with a warmer or more focused upper string. This product offers the G and C individually so you can add exactly what you need. The two voices What each string brings. G · Spiral Rope Steel / Tungsten Radiant lower-mid Spiral rope steel core with tungsten winding. A radiant, carrying G that stays tight under heavy bow pressure. Tension 14.0 kg. Ball end (nickel). C · Spiral Rope Steel / Tungsten Deep, resonant bass Spiral rope steel core with tungsten winding. A deep, resonant C with clean articulation and strong pizzicato sustain. Tension 13.5 kg. Ball end (brass). Playability Instant response, cuts through any texture. The Spirocore pair speaks instantly, cuts through dense ensemble textures, and tolerates assertive bow weight without losing centre. Break-in is short, and the feel remains supple and predictable, making fast passages and register shifts feel effortless. These strings are well-suited to concertos, recitals, and principal orchestral roles where projection and clarity in the lower register are essential. Their bright, focused character also makes them a popular choice for jazz and contemporary cello playing where a clear, penetrating lower-string tone is prized. Technical specifications Materials and construction. G Flexible spiral rope steel core, tungsten winding, 14.0 kg, ball end (nickel) C Flexible spiral rope steel core, tungsten winding, 13.5 kg, ball end (brass) Size 4/4 cello Origin Manufactured by Thomastik-Infeld, Vienna, Austria Frequently asked Spirocore Tungsten G and C, in short. Which string should I order? Order the G or C depending on which you need to replace. If replacing both lower strings at the same time, choose the G and C Complete set from the selector. Why are these sold as G and C only, without A and D? The Spirocore Tungsten G and C are specifically designed as lower-string options. Many players use them as part of a hybrid setup, pairing the projecting lower register of the Spirocore with a different brand's A and D that better suits the upper register of their instrument. No standard Spirocore A and D set is available here. How long do Spirocore Tungsten strings last? Lifespan depends on playing hours, perspiration, and environment. Spirocore strings are known for their durability and are often reported to outlast many other string types at a professional level. Replace when the tone becomes dull or the pitch is unreliable. How long do new Spirocore strings take to settle in? Break-in is short. Allow 24 to 48 hours of normal playing. The strings settle quickly and hold pitch reliably thereafter. Are these genuine Thomastik-Infeld strings? Yes. Symphonia stocks Thomastik-Infeld Spirocore through the official supply chain. If a string is faulty on arrival or fails prematurely under normal use, we arrange the replacement directly.
