This is a single length gut core string with a copper wire winding and a thin silk layer wound onto the core between the gut and wire. The surface of the round wire polished for a smooth surface, helping the tone to be quick and bright. The end of the string that goes into the tailpiece is knotted and there is a loop of gut on the end. This knot will hold the string in most historical tailpieces, but may slip through a modern tailpiece.
