Dr Oliver Sacks examines the power of music through the individual experiences of patients, musicians, and everyday people. Among them: a surgeon who is struck by lightning and suddenly becomes obsessed with Chopin; people with ???amusia???, to whom a symphony sounds like the clattering of poets and pans; and a man whose memory spans only seven seconds ??? for everything but music. Dr Sacks describes how music can animate people with Parkinson???s disease who cannot otherwise move, give words to stroke patients who cannot otherwise speak, and calm and organize people who are deeply disoriented b Alzheimer???s or schizophrenia. This classic of neurology is a book that alters our conception of who we are and how we function, and shows us an essential part of what it is to be human.
