The Stylophone appears on a few commercial recordings, most notably David Bowie’s “Space Oddity” and “Slip Away” and the commercial rave single “Stylophonia” by Two Little Boys in 1991. Kraftwerk used the Stylophone on the track “Pocket Calculator” from their album Computer World.
The Dubreq Stylophone is a miniature stylus operated synthesizer invented in 1967 by Brian Jarvis. It consists of a metal keyboard played by touching it with a stylus – each note being connected to a cheap voltage-controlled oscillator via a different-value resistor – thus closing a circuit. Some three million Stylophones were sold, mostly as children’s toys. Rolf Harris appeared for several years as the Stylophone’s advertising spokesman in the United Kingdom.
