This volume is a collection based on the Royal Musical Association's Mozart Conference of 1991, the principal scholarly event in the English-speaking world in commemoration of the bicentenary. It includes essays placing Mozart in the context, in Salzburg and Vienna, in which he worked, explaining aspects of his life and work hitherto obscure; essays interpreting his instrumental music; and a substantial series of studies on different aspects of his operas, from Lucio Silla to La clemenza di Tito, with particular stress on the creative processes in the Da Ponte operas.
