Mozart's collaborations with the librettist Lorenzo Da Ponte led to the composition of three of the great masterpieces of opera. This book, designed to guide the reader to a deeper understanding and appreciation of these enigmatic works, charts the musical, cultural, and social context in which they were written--the tastes and expectations of the contemporary opera audience, Mozart's intentions and aspirations in a period of rapid intellectual and political change, Da Ponte's views of opera, and the practical logistics of opera production at the time. Together, these strands provide illuminating insights into Mozart's creative process and the functions of eighteenth-century opera.
