The Ondioline is one of the earliest monophonic (single-note) electronic synthesizers, invented by French inventor Georges Jenny in the 1940s. Designed to be an affordable, versatile instrument that could emulate various acoustic instruments, it features a unique spring-mounted, side-to-side vibrato keyboard, a knee lever for volume control, and built-in filters and sub-octave dividers. Jean-Jacques Perrey , was a French electronic music performer, composer, producer, and promoter. He is considered a pioneer of pop electronica. Perrey partnered with composer-performer Gershon Kingsley to form the electronic music duo Perrey and Kingsley, who issued some of the first commercial recordings featuring the Moog synthesizer. Perrey was also one of the first to promote, perform, and record with the Ondioline, developed by Georges Jenny. #ondioline #jeanjacquesperry #synthesizer #electronicmusic
