A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal (usually steel). It resonates at a specific constant pitch when set vibrating by striking it against a surface or with an object, and emits a pure musical tone once the high overtones fade out.
Over time, tuning forks were adapted for use in medical and therapeutic settings, where their precise frequencies have been harnessed for healing and therapeutic purposes. [3] Tuning forks are known for their nearly pure frequency response, emitting a clear, unwavering tone that is free from the complex overtones found in other instruments.
Tuning-fork style diagram of the Hubble sequence. The tuning fork scheme divided regular galaxies into three broad classes – ellipticals, lenticulars and spirals – based on their visual appearance (originally on photographic plates). A fourth class contains galaxies with an irregular appearance.
Tuning Fork is a 1979 Soviet two-part television feature film. The film uses drawings by Nadya Rusheva.Alexander Gradsky appears in the film as himself. The song from the film 'Baby', performed by Gradsky, became popular for playing in the yards with a guitar.
Experiment using two tuning forks oscillating at the same frequency.One of the forks is being hit with a rubberized mallet. Although the first tuning fork hasn't been hit, the other fork is visibly excited due to the oscillation caused by the periodic change in the pressure and density of the air by hitting the other fork, creating an acoustic resonance between the forks.

A tuning fork or electronic tuning device may be used as a reference pitch, though in ensemble rehearsals often a piano is used (as its pitch cannot be adjusted for each performance). Symphony orchestras and concert bands usually tune to an A 440 or a B♭ , respectively, provided by the principal oboist or clarinetist , who tune to the ...
In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them. The effect is most noticeable when the two bodies are tuned in unison or an octave apart (corresponding to the first and second harmonics , integer multiples of the inducing frequency), as there is the greatest ...
