As a musical instrument used for producing specific pitches or frequencies when struck, a tuning fork is chrome-plated; designed to vibrate at a particular frequency associated with a musical note. The blued steel material provides the tuning fork with strength, durability, and a distinct bluish tint. Utilize tuning forks for demonstrations involving stobes, mirrors, water, ping pong balls, oscilloscopes, and lasers.

Tuning forks have multiple uses, including as a reference for tuning musical instruments, in physics and acoustics experiments, for medical diagnostics, and in vibrational therapy. They are precise tools with consistent and known frequencies that are useful for sound and sensory studies, as well as for promoting relaxation and addressing health goals.
