tuning fork

Translation
tuning fork
a steel instrument consisting of a stem with two prongs, producing a musical tone of definite, constant pitch when struck, and serving as a standard for tuning musical instruments, making acoustical experiments, and the like.
[1765-75]

▪ mechanical device
      narrow, two-pronged steel bar that when tuned to a specific musical pitch retains its tuning almost indefinitely. It was apparently invented by George Frideric Handel's trumpeter John Shore shortly before Shore's death in 1752.

      Because it produces a nearly pure tone (without overtones), it is useful in experimental study of the physics of sound. It has also been used in musical instruments—e.g., the dulcitone, or typophone, a set of graduated tuning forks struck by felt hammers by means of a keyboard mechanism.
