Device that generates sounds of constant pitch when struck
Tuning fork by John Walker stamped with note (E) and frequency in hertz (659)
A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs (tines) formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out. A tuning fork's pitch depends on the length and mass of the two prongs. They are traditional sources of standard pitch for tuning musical instruments.
The tuning fork was invented in 1711 by British musician John Shore, sergeant trumpeter and lutenist to the royal court.[1]
