Saturday April 25
11:00am-12:30pm
Workshop: Extended Technique
facilitated by Sara Gold
A hands-on audio workshop incorporating visual elements which tie together concepts and techniques associated with the physical and neurological perception of sound.
The re-creation of a striking, though inaccurate, 18th Century experiment originally designed to demystify the underlying cause of the Aurora Borealis will be installed at VIVO and utilized by workshop participants to clearly illustrate core concepts regarding the kinetic energy of sound. In this installation of the experiment, a beam of sunlight is passed through a prism and cast into a vapor cloud that is visibly agitated by electronically generated sound waves, emitted from speakers and subwoofers, to be controlled by participants.
Workshop participants will have a chance to interact with the resonant frequency of the building and
suspended objects, experiencing first hand the transfer of kinetic energy through solid medium.
Introductions will be made to particularly engaging peculiarities of how our brains perceive and
interpret sound, through demonstration and discussion, and aspects of electromagnetism will be
explored visually by participants with the interactive play of magnets on a cathode ray tube monitor
which serves to distort the image of the experiment in a way reflective of our own brains perceptual
structures.
