Ringing Minds is a collaborative work created by David Rosenboom, Tim Mullen and Alexander Khalil, premiered on May 31st, 2014, at Mainly Mozart's "Mozart and the Mind" festival in La Jolla, California. Ringing Minds explores collective brain responses interacting in a spontaneous musical landscape aided by recent advances in sensing technology and powerful tools for analyzing electroencephalograms (EEGs) of multiple brains.
Ringing Minds—collective brain responses interacting in a spontaneous musical landscape (2014), created in collaboration with computational neuroscientist and musician, Tim Mullen, and cognitive scientist and performer-composer, Alex Khalil, offers a significant step forward in the evolution of BCMI (Brain-Computer Music Interfacing) paradigms. Using a technique called hyperscanning, the brains of several musical listeners are treated as one hyper-brain to investigate concepts about complexity and structural forms manifested concurrently in music and multiple brains, along with resonances that can be detected within and between listeners and performers. In Ringing Minds, resonant patterns detected in the hyper-brain’s activity are sonified with a field of ringing, electronic sound resonators. Two musicians, one with an electronic violin and another with a unique xylophone-like instrument made of stone, called a lithophone, respond to activity in this sound field. When, in turn, the hyper-brain responds to sounds created spontaneously by the musicians, the resonator field undulates, as if stones were being tossed into a vast sonic lake, and we hear their ever expanding ripples.
