What is the purpose of the Arts? Can music, literature and visual art change our lives physically and socially, as well as personally? Adam Rutherford explores the power of the arts and how it might be defined and explained.

Engaging with the arts is one of our most powerful tools for unlocking health and happiness argues Daisy Fancourt. She is is Professor of Psychobiology and Epidemiology at University College London and Director of the World Health Organisation Collaborating Centre on Arts and Health. In her new book, Art Cure, she shows how songs support the development of children's brains; how dance can build neural pathways; how theatre and exhibitions can decrease pain, stress and depression and how the arts can improve the functioning of every major organ system in the body. Drawing on the latest research research in a range of scientific fields, she traces a connection between the arts and human flourishing.

Earliest Stories: Stories, Novellas, Humoresques, 1880-1882 is a collection of the Russian writer Anton Chekhov's work while he was still a student of medicine. In his juvenilia we see flashes of insight alongside comedy, compassion and a developing narrative voice. Rosamund Bartlett, translator, biographer and cultural historian writes about how stories have long been dismissed, but written as his family faced financial crisis, reveal much about the threads that connect together in his life and work.

BBC Radio 3 presenter Tom Service explores how music transports and defines us in his new book. In A History of the World in 50 Pieces, he examines how classical music reflects our changing politics, society and technological advances - and how composers, musicians and listeners have shaped history. From Bach to Beethoven via the Happy birthday song, he explores the power of music to connect and and challenge us.
