More than 20 years after his classic study "Mozart in the Inner Workings of His Languages," Hanns-Josef Ortheil once again delves deeply into the mystery of Mozart's music. In his extensive book, a blend of diary, narrative, and essay, he explores the fascination of Mozart in a very personal way, inviting the reader to share in his listening experience. He decodes not only many of the well-known and lesser-known pieces by this great composer but also discusses his operas and their creation in detail. This book is aimed at anyone who wishes to learn more about Mozart's genius, to listen to his music more intensely, and to deepen their understanding of Mozart's world of life, thought, and emotion.
