I Heard There Was a Secret Chord: Music as Medicine by Daniel J. Levitin 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. In his latest work, neuroscientist and New York Times best-selling author Daniel J. Levitin (This Is Your Brain on Music) explores the curative powers of music, showing us how and why it is one of the most potent therapies today.
