For Frido Mann, music has played a significant role throughout his life. As the son of a violist and the grandson of an author who turned music into world literature, Frido Mann has been exploring the musical cosmos since his childhood. The focus is not solely on the purely artistic fascination, but primarily on the question of the ethical dimension that music conveys. Frido Mann's book is a personal journey through music history that does not claim to be exhaustive. He describes listening experiences and encounters that are embedded both culturally and autobiographically, offering his readers a self-portrait that invites them to rediscover and re-listen.
