tuning fork

A tuning fork is a metal instrument with two prongs that vibrate when struck, producing a specific, pure musical tone. Its purpose is to help musicians tune their instruments accurately by matching other sounds to its consistent pitch. The vibrations generate a steady sound wave at a particular frequency, which remains stable over time, making it a reliable reference for tuning. Tuning forks are commonly used in music, physics, and medical settings to test hearing or measure vibrations.
