Electric guitars can have string trees near the tuning pegs to mute this type of reverberation. The string length behind the bridge also must be as short as possible to prevent the resonance. String resonance is a factor in the timbre of a string instrument. Tailed bridge guitars like the Fender Jaguar differ in timbre from guitars with short bridges, because of their (extended) floating bridge. The Japanese Koto is also an example of an instrument with occurring string resonance.
Sometimes string resonance is used in the construction of the instrument, like for instance the Sympathetic strings in many Eastern instruments.
According to a 2007 Grove Music Online article on "duplex scaling", Steinway developed a system of Aliquot stringing to provide sympathetic resonance, with the intention of enriching the treble register of the piano. In the "octave duplex" piano by Hoerr of Toronto, each note had four strings, of which two, three or four could be struck by the hammer depending on the depression of any of four pedals. Steinway’s duplex scale was inspired a half century earlier by an experiment conducted by the German piano maker Wilhelm Leberecht Petzoldt, in which a small bridge was placed behind the standard larger one with the intention of maximizing the potential additional resonance of a sympathetically vibrating additional length of string.
The following table shows the created resonating overtones on the koto for various positions on a stopped string (the proportion being between the "played" portion of the string and resonant portion, the remaining length of the string).
