Thomastik-Infeld offers the Spirocore, Belcanto, Belcanto Gold and Dominant, Versum , Spirit! and the newest offering: Rondo strings. The Spirocore strings offer less inertia and are more responsive, especially in the lower two, C and G strings. While the Spirocore cello strings are traditional (and the old staple), the newer Belcanto (and Gold) strings are made with new technology and alloys that offer something new, but retain the ‘old’ sound that cellists like. The Dominant brand cello strings are very responsive strings and are made with a perlon core. This gives the old “gut” feel and sound, without the headache of using gut strings.
Belcanto strings are designed for professional cellists seeking a clear, focused, and bell-like tone. With steel cores and chrome winding, they deliver quick response, evenness across strings, and minimal play-in time.
