I came across this story in this month’s Wire. Masaki Batoh uses an elaborate headset that converts brain waves from various lobes of the brain to generate tones. Rather than playing the instrument you improvise by going into a meditative state. The video above shows Batoh performing by showing different images to a volunteer rigged up to his brain harp. Batoh hopes that his machine and music can be be used as therapeutic tools as well as live performances.
It seems being in a calm, trancey state produces a certain sound, but what do other emotional states sound like? In the future will we pay to see a gig of someone performing the sound of mild depression accompanied by childhood fear of wasps?
