Abstract
A string for use on musical instrument is made of a core wire composed of long filaments, sheathed with a thick mantle of a precious metal such as gold, silver, platinum, palladium, copper, or the like, or of other metal (5) having excellent ductility, or of an alloy of these metals, or of a synthetic resin or ceramic. It becomes possible to change the density per unit length, thus to enable the adjustment of sound quality and the attenuation rate, and the selection of the basic vibration frequency. It also becomes possible to adjust the tensile strength of the string, thus to enable the selection of the tensile strength and the density in accordance with the type of the musical instrument which is strung and the type (number) of the string. It also becomes possible to maintain the sound quality of the wound wire for bass strings for a long term, and to take easily countermeasures against abrasion with a partial hardening treatment. Furthermore asset value is created and a colorful, attractive appearance is provided by using precious metals for the material.
