Le Dubreq Stylophone est un instrument de musique électronique miniature, créé en 1967 par Brian Jarvis.
Il se compose d'un clavier métallique de 20 notes sur lequel on joue à l'aide d'un stylo relié à un fil électrique, ce qui ferme le circuit et produit la note. Le son produit est pauvre selon certains musiciens et l'appareil pourrait se dire rapproché du gadget que de l'instrument de musique. Néanmoins, les artistes utilisant le stylophone ajoutent le plus souvent des effets sonores (grâce à des pédales multi-effets) pour enrichir le son et en faire un véritable synthétiseur.
Durant sa vie éphémère, le stylophone fut un énorme succès commercial, avec trois millions d'exemplaires vendus, surtout en tant que jouet. On lui connaît quelques rares utilisations musicales, par des artistes comme Pulp, Kraftwerk, Erasure, le groupe The Velvet Underground et David Bowie (dans la chanson Space Oddity).
On peut noter sa réutilisation grâce à des artistes tels que Little Boots, Spirit of the matter, Dionysos (tournée acoustique 2009) ainsi que Charlie Winston lors de son concert au Point gamma 2009 de l'École polytechnique.
The Stylophone is a miniature analog stylus-operated keyboard. Invented in 1967 by Brian Jarvis,[1] it entered production in 1968, manufactured by Dubreq. It consists of a metal keyboard played by touching it with a stylus—each note being connected to a voltage-controlled oscillator via a different-value resistor—thus closing a circuit. The only other controls were a power switch and a vibrato control on the front panel beside the keyboard, and a tuning control on the rear. Some three million Stylophones were sold, mostly as children's toys.
The Stylophone was available in three variants: standard, bass, and treble, the standard one being by far the most common. There was also a larger version called the 350S with more notes on the keyboard, various voices, a novel 'wah-wah' effect that was controlled by moving one's hand over a photo-sensor, and two styluses.
In the mid-1970s a new model appeared which featured pseudo-wood on the speaker panel and a volume control. This was shortly before the Stylophone ceased production altogether in 1975.
The entertainer Rolf Harris appeared for several years as the Stylophone's advertising spokesman in the United Kingdom, and appeared on many "play-along" records sold by the manufacturer.[2]
