Sub-harmonic frequencies are frequencies below the fundamental frequency of an oscillator in a ratio of 1 / x. For example, if the fundamental frequency of an oscillator is 440 Hz, sub-harmonics include 220 Hz (1/2) and 110 Hz (1/4).

Subharmonics can be produced by signal amplification through loudspeakers.[1]

Violinist Mari Kimura is purported to be able to produce subharmonic notes on the violin.
