A fascinating journey through the world's musical cultures. Every culture on Earth has music. Every culture that's ever existed has had it, but we don't exactly know why. Music is not like food, shelter, or having opposable thumbs. We don't need it to live, and yet we can't seem to live without it. Glenn Dixon travels the globe exploring how and why people make music. From a tour of Bob Marley's house to sitar lessons in India, he experiences music around the world and infuses the stories with the latest in brain research, genetics, and evolutionary psychology. Why does music give us chills down the backs of our necks? What exactly are the whales singing about and why does some music stick in our minds like chewing gum? Through his adventures, Dixon uncovers the real reasons why music has such a powerful hold on us - and the answers just might surprise you
