Music is one of humanity's oldest medicines. From the Far East to the Ottoman Empire, Europe to Africa and the pre-colonial Americas, many cultures have developed their own rich traditions for using sound and rhythm to ease suffering, promote healing, and calm the mind. Neuroscientist Daniel J. Levitin explores the curative powers of music, showing us how and why it is one of the most potent therapies today. He brings together, for the first time, the results of numerous studies on music and the brain, demonstrating how music can contribute to the treatment of a host of ailments, from neurodegenerative diseases such as Parkinson's and Alzheimer's, to cognitive injury, depression, and pain. Levitin is not your typical scientist--he is also an award-winning musician and composer, and through lively interviews with some of today's most celebrated musicians, from Sting to Kent Nagano and Mari Kodama, he shares their observations as to why music might be an effective therapy, in addition to plumbing scientific case studies, music theory, and music history. The result is a work of dazzling ideas, cutting-edge research, and jubilant celebration. I Heard There Was a Secret Chord highlights the critical role music has played in human biology, illuminating the neuroscience of music and its profound benefits for those both young and old. -- Provided by publisher.
