The Wobble Organ was a monophonic electronic instrument created by Bell Laboratories electrical engineer Larned A. Meacham in 1951. The device was intended as an inexpensive, portable recreational instruments where a family could get together to create an electronic “Barbershop quartet”. The Wobble Organ was not intended as a commercial instrument but designed for the popular self-build market of the time.
The instrument was designed to be playable by performers who “have little or no experience with the manipulation of conventional musical instruments”(1). Meacham’s solution to this was to avoid using a conventional keyboard and instead control the Wobble Organ with a pivoted joystick, or ‘wobble arm’ sliding against a curved form marked with pitch intervals ( a similar control method to Jörg Mager’s Sphärophon of 1926) . By raising and lowering the joystick the player could alter the pitch of a single neon/thyratron sawtooth oscillator over two and half octaves – the note could be turned on and off with a hand-held button.
