This Ted Talk, given by Alan Harvey, explains the many ways that music affects the human body and brain. Harvey explained the history and use of music within our lives. In this lecture, Alan Harvey explained the ways in which music triggers signals in our brain. He demonstrated the impact of music on the brain through images of the brain, showing the alpha waves notated by an EEG, and by giving examples of a video with peaceful music and then again with a faster and darker melody.
