The Larsen Magnacore Arioso cello string set offers wide-ranging freedom of expression without compromising on power. The strings in the set are designed to work well with both older Italian instruments and cellos by modern makers. Magnacore Arioso cello strings come in 4/4 size, medium tension and with a ball end, delivering full projection combined with a breadth of tonal colors. The A and D have a solid steel core wound with steel, and the C and G have a multi-strand steel core wound with tungsten.
