Audio visual artist and composer Kathy Hinde explores the sonic complexities and possibilities of combining glass vessels with shifting water levels in this Cryptic commission for Sonica 2014. Sound tones are produced live via a microphone that feeds back inside each glass vessel. As the water levels change, the feedback is tuned to different pitches based on the resonant frequency of the remaining space in each glass vessel. The work forms both a sound sculpture and a live instrument for performance.
A Cryptic commission for Sonica, Tipping Point is a collaboration with John Rowden at the Scientific Glass Workshop in the School of Physics at the University of Bristol with software designed by Matthew Olden.
