In these 12 essays, the author explores the concept of opera as a dramatic event and an essential moment in the history of theatre. Examining the meaning of opera and the devices that produce and transmit this meaning, he looks at the complex verbal, musical and scenic mechanisms in parts of 'La Sonnambula', 'Ernani', 'Aida', 'Le Nozze di Figaro', 'Macbeth' and 'Il Trovatore'. He argues that approaches to the study of opera must address performance, interpretation, composition, reception, and cultural ramifications.
