American Heritage® Dictionary of the English Language, Fourth Edition
- n. A small two-pronged metal device that when struck produces a sound of fixed pitch that is used as a reference, as in tuning musical instruments.
Century Dictionary and Cyclopedia
- n. A steel instrument with two prongs, designed to produce, when struck, a musical tone of some particular pitch. Its invention is ascribed to John Shore, in the middle of the eighteenth century. Tuning-forks are particularly useful because their tone is comparatively free from harmonics, and because their pitch is not disturbed by ordinary changes of temperature. They are therefore much employed in acoustical investigation and to furnish convenient standards of pitch. Compare
tonometer, and see pitch.
GNU Webster's 1913
