The World in Six Songs: How the Musical Brain Created Human Nature

Dr. Levitin identifies six fundamental song functions or types-friendship, joy, comfort, religion, knowledge, and love-then shows how each in its own way has enabled the social bonding necessary for human culture and society to evolve. He shows, in effect, how these "six songs" work in our brains to preserve the emotional history of our lives and species.

Dr. Levitin combines cutting-edge scientific research from his music cognition lab at McGill University and work in an array of related fields; his own sometimes hilarious experiences in the music business; and illuminating interviews with musicians such as Sting and David Byrne, as well as conductors, anthropologists, and evolutionary biologists. The World in Six Songs is, ultimately, a revolution in our understanding of how human nature evolved-right up to the iPod.
