A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs 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.
The number of tines on tools varies widely – a pitchfork may have just two, a garden fork may have four, and a rake or harrow many.
