Your brain-waves can be turned into music, and it’s amazing. OK, that’s a bit simplistic – here’s the bigger picture: physiological processes in the brain create potential fluctuations that detectors on the head can pick up via electroencephalography (EEG). They can then be algorithmically identified so that strings of brain activities – your thoughts – can become different musical notes! And with a controlled flow of thoughts, your own brain becomes a composer. And then this creates a feedback loop – listening to the music creates new thoughts, which creates new music… come and listen for yourself!
