It was invented by Constant Martin in 1947 in Versailles. It consists of a keyboard and a separate amplifier and speaker unit. The keyboard usually covered three octaves, and had a number of switches to alter the tone of the sound produced, add vibrato, and provide other effects. The Clavioline used a vacuum tube oscillator to produce a buzzy waveform, almost a square wave, which could then be altered using high-pass and low-pass filtering, as well as the vibrato. The amplifier also deliberately provided a large amount of distortion.
Several models were produced by different companies; among the more important were the Standard, Reverb, and Concert models by Selmer in France and Gibson in the United States in the 1950s. The 6-octave model employing octave transposition was developed by Harald Bode, and under licensed by Jörgensen Electronic in Germany. In England the Jennings Organ Company's first successful product was the Univox, an early self-powered electronic keyboard inspired by the Selmer Clavioline. In Japan, Ace Tone's first prototype, Canary S-2 (1962), was based on the Clavioline.
The clavioline has been utilized on a number of recordings in popular music as well as in film. A selection follows.

"To quote Selmer's service manual, “The Amplifier is an unusual type insofar as a large amount of distortion is deliberately obtained. This distortion is used to further modify the signal and contributes in no small measure toward the construction of the authentic tone. The Amplifier is, therefore, an integral part of the instrument...”"

"Probably Jennings [Musical Industries]’ first “portable” keyboard instrument was the Univox ... Usually assumed to be the instrument used on The Tornados’ “Telstar” (although it may actually have been a Clavioline, but that’s another story), it was born in the very early 1950’s. ... / Contrary to popular belief, the Univox is NOT a Clavioline. Derek Underdown tell it in his own words: “...Tom Jennings ... found a local electronic engineer, Les. Hills, who studied the Clavioline and designed another circuit different to the existing French patent. ...In about 1951/1952 the Univox took off in a big way due to its competitive price and Tom’s country wide marketing program. ... So, No the Clavioline was not the same as the Univox, only catered for the same market.” "
