It is used as a reference for accurate pitch, and to mark time in quartz digital watches. In appearance, a tuning fork is a two-pronged metal fork that is shaped like a U and extends from a handle. Most people are familiar with the fundamental mode of this device, which is the long-lasting mode used as a standard for pitch.
