The Mendelssohn Companion represents a collection of advanced scholarly research in Mendelssohn studies that examines the composer's life and music. In recent decades, studies of his music manuscripts have discovered much previously overlooked work, and a reconsideration of his biography has permitted a more realistic portrayal of Mendelssohn. The first three chapters of this volume place the composer in his intellectual context and discuss his family and social circle and his professional activities. Later chapters examine the major areas of his compositional work, providing new analytical observations, contextual perspectives, and interpretations. Historical views and documents are included with each chapter and are all newly translated.The new material in this fully documented study will appeal to scholars, students, and music enthusiasts alike. An updated bibliographic list of Mendelssohn's works, which identifies the autograph manuscripts and the most important published editions will be of special interest.
