Charles Darwin meets the Beatles in this attempt to blend neuroscience and evolutionary biology to explain why music is such a powerful force. In this rewarding though often repetitious study by bestselling author Levitin (This Is Your Brain on Music), a rock musician turned neuroscientist, argues that music is a core element of human identity, paving the way for language, cooperative work projects and the recording of our lives and history. Through his studies, Levitin has identified six kinds of songs that help us achieve these goals: songs of friendship, joy, comfort, knowledge, religion and love. He cites lyrics ranging from the songs of Johnny Cash to work songs, which, he says, promote feelings of togetherness. According to Levitin, evolution may have selected individuals who were able to use nonviolent means like dance and music to settle disputes. Songs also serve as memory-aids, as records of our lives and legends. Some may find Levitin's evolutionary explanations reductionist, but he lightens the science with personal anecdotes and chats with Sting and others, offering an intriguing explanation for the power of music in our lives as individuals and as a society.
Note added 8/28... A very negative critical review of this Levitin book, by John Carmody, has just appeared in Nature. Now I'm thinking maybe I shouldn't have ordered it.
