A demonstration of Hans Jennys original acoustic tonoscope, showing how the human voice can create harmonic patterns in sand spread over a taut rubber membrane. Christian Stuten was Jenny's assistant for 14 years, and photographed most of the images in the book Cymatics: A Study of Wave Phenomena and Vibration.
These experiments were performed by Hans Jenny in the 1960s. Here he vibrates Lycopodium, (a fine powder which is actually the spores of a club moss) using audible sound. The powder rises up from the surface of the taut rubber membrane, and creates a variety of amazing phenomena. At certain frequencies, it even assumes a circulatory pattern above the surface of the membrane, both generated and contained by the force field of the sound pulsations.
John Beaulieu describes sensing pulsation through our ears, and how our listening effects everything from our mood to our posture, to our perception of ourselves as vibratory beings resonating with myriad energy fields. Followed by, The Universal Tone, a poem written and recited by Jeff Volk. From the award-winning program, Of Sound Mind and Body: Music & Vibrational Healing.
