With a passion for languages and music, Edner Xavier looks into archeology, anthropology, science, and philosophy for the origins of sound, its influence on our lives, and its impact on our societies. Starting from a thirty-five-thousand-year-old sound, he goes on to evoke the memory and work of the composer J. S. Bach particularly and considers modern classical music and its future. In this essay, he also explores the importance and value of various profane and religious musical genres in order to show how they all can restore humanism and harmonize our planet.
