  1. Biosensors & Biofeedback in Music Chelsea Douglas

  2. History & Early Development • Biofeedback first became first became viewed as a musical tool in the late 1960s. • David Rosenboom (Brainwave Music) and Alvin Lucier were two American composers who explored the use of biosensors in music. • Now biosignals with music are used as digital signals and can be used to control aspects of the music • Dubostand Tanaka refer to this as bio-control instead of bio-feedback. • Biofeedback is often related to emotional state • Depending on the individual biofeedback can be controlled.

  3. Measures of Biofeedback • Measures of Biofeedback include: • Galvanic Skin Response • Dependent on moisture level • Heart Rate Monitoring • Body Temperature • EEG (Electroencephalography) • Sensors placed on scalp measure electrical activity/ionic current flows within the neurons of the brain

  4. Example Device • Brain Pulse Music Machine • Headset • Measures activity in the frontal (ability to recognize future consequences resulting from current actions) and parietal (sensory information) lobes • Converts this activity into sounds • Approximate cost = $699.99

  6. Composition & Performance Examples • Alvin Lucier, (American Composer) • Clocker (1991): http://www.lovely.com/titles/cd1019.html • MassimilianoPeretti (Contemporary Artist) • Amigdalae Project (2005) • Measures Biofeedback with GSR, EEG, Body Temp and Heart Rate • Audience views video art while biofeedback controls and alters the musical accompaniment.

Other Uses • Music Therapy • Reward controlled by biofeedback • Research • Companies • Market products with biofeedback to create custom music • Exercise • Relaxation • Performance anxiety • Idea that continuous exchange of feedback between music and individual enhances experience • Relaxation
