The four members of the violin family have changed very little In hundreds of years. Recently, a group of musi- cians and scientists have constructed a "new" string family. 16 Founding a Family of Fiddles Carleen M. Hutchins An article from Physics Today, 1967. New measmement techniques combined with recent acoustics research enable us to make vioUn-type instruments in all frequency ranges with the properties built into the vioHn itself by the masters of three centuries ago. Thus for the first time we have a whole family of instruments made according to a consistent acoustical theory.
