The Stylophone is a miniature analog synthesizer played with a stylus. Invented in 1967 by Brian Jarvis, it entered production in 1968 and was manufactured by Dubreq in London. Around three million units were sold during its original production run. Although primarily marketed as a toy, it was also used by musicians such as John Lennon, Kraftwerk and David Bowie. The Stylophone was relaunched in 2007 by the toy company Re: in partnership with Dubreq, and several new models have since been released.
