Thomastik Infeld Spirocore cello strings stand alone among Thomastik-Infeld's string options for their quick response and focused sound, making them a popular string selection among cellists of all levels.

An especially popular choice for the lower strings within mixed sets, Spirocore cello strings are known for their clarity and focus. The brightness of sound produced by the Spirocore G and C strings make them a perfectly viable option for clearing up an otherwise muddled lower register.

Spirocore strings are made of multi-wire, spiraled steel core, similar to a rope core. Spirocore cello strings offer a brightness and strong projection, with a more pliable touch under the fingers, while remaining extremely responsive and crisp.
