Abstract:

Program notes: This performance draws on a natural feature of a particular class of chaotic oscillators described by Julien Sprott, namely that they require a driving force in order to perform as chaotic attractors. In the unmodified equations driving forces are introduced mathematically, however, as we calculate the chaotic systems in real-time we open the door to using a performers audio signal as an input force. This class of oscillator exhibits interesting behavior in response to different frequency inputs; in particular, the systems are sensitive to changes in low frequency tones. This encourages the use of Just Intonation as a method of determining tuning systems with easily defined difference tones; the scale developed by Kraig Grady features many difference tones in an excitable range for the chaotic oscillators. About the performers: Mark Havryliv is a doctoral student developing a haptic musical instrument at the University of Wollongong. Aside from that research, he is interested in the musical possibilities of integrating real-time sonification with other disciplines like game design and creative writing. Kraig Grady, an Anaphorian now living in Australia, composes almost exclusively for acoustic instruments of his own making or modification tuned to just intonation. Often his work is combined with his Shadow Theatre productions. His work has been presented at Ballhaus Naunyn Berlin (Germany), the Chateau de la Napoule (France), the Norton Simon Museum of Art, the UCLA Armand Hammer Museum, the Pacific Asia Museum, the Los Angeles Philharmonics American Music Weekend and New Music America 1985. He was chosen by Buzz Magazine as one of the "100 coolest people in Los Angeles". Kraig Grady - Just Intonation Tuned Marimba Mark Havryliv - Saxophone
