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 example is a monochord, with only one string. It came from the Smithsonian Institution Instrument Room, and was probably made by Rudolph Koenig in Paris.
