Description
A sonometer demonstrates the relationship between the frequency of the sound produced by a plucked string, and the tension, length and mass per unit length of the string. This 8-string example came from the Smithsonian Institution Instrument Room, and was undoubtedly made by Rudolph Koenig in Paris. Koenig termed it a great sonometer according to M. Barbereau, referring to the French musician, Mathurin August Balthazar Barbereau (1799-1879).
