harmonic oscillator

n.
A physical system in which some value oscillates above and below a mean value at one or more characteristic frequencies. Such systems often arise when a contrary force results from displacement from a force-neutral position and gets stronger in proportion to the amount of displacement, as in the force exerted by a spring that is stretched or compressed or by a vibrating string on a musical instrument.
