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 after waiting a moment to allow some high overtones to die out. The pitch that a particular tuning fork generates depends on the length of the two prongs. Its main use is as a standard of pitch to tune other musical instruments.

Famous quotes containing the word fork:
“Every country we conquer feeds us. And these are just a few of the good things we’ll have when this war is over.... Slaves working for us everywhere while we sit back with a fork in our hands and a whip on our knees.”
—Curtis Siodmak (1902–1988)
