Abstract
A silent stringed musical instrument includes a wooden body, a neck projecting from one end of the wooden body, peg screws attached to the neck, a tail piece attached to the body, strings stretched between the peg screws and the tail piece, a bridge attached to the body in such a manner as to be held in contact with the strings and an electric system for producing an electric signal from the vibrations of each string; when a player bows the silent stringed musical instrument for playing a tune, the electric system converts the vibrations of each string to the electric signal so as to produce electric sound; however, the body hardly vibrates, because viscoelastic layers are inserted between wooden plates.
