Optical Sounders, An introduction into Graphical, Ornamental Sound

 

 In this art they, the darknesses and brightnesses, constitute the woof of the play. They carry a chief burden of the transmitted feeling.

The Fine Art of Light-Color Playing

 

Inspired by the discoveries pursued in Film recording technologies, in the late ‘20s, Graphical Sound emerged as a new form of sound synthesis in which captured hand-drawn shapes on paper or film were converted into voltages and played out loud.

To understand better the background of associating images with sounds in a synesthetic approach, we will have a look, starting with the 17th century, at some of the earliest ideas and attempts in history that regard systems of sound visualisation and visual music. Amongst others, the Jesuit colour organs, Harmonographs, Cladni’s Klangfiguren and Mary Hallock Greenewalt’s methods.

We will explore the emergence of the Sound-on-Film Technique and the movements that followed in Soviet Russia and Germany and delve into a compendium of interesting machines and inventions that were to establish one of the first sound synthesis techniques. 

The theoretical introduction will be followed by a hands-on exercise in which we will draw and convert our hand-drawn shapes into sound using analogue circuitry. We will explore the juxtaposition of the historical and theoretical explorations into graphical sound with contemporary electronic techniques. The attendees will gain a better understanding of Opto-acoustical techniques to use them for their own musical experiments.
