Numerous musical excerpts complement this comprehensive identification and evaluation of nearly 100 symphonies. The book attempts to place each symphony in a musical and cultural context, to reveal how the symphonies were performed and to discover what role they played in Mozart's creative life. The book's goals include the reinterpretation of a number of documents that have been available to specialists, but only partially understood, and to gather and evaluate a great deal of information about the symphonies and their context that has, until now, been widely scattered in technical publications. Some documents new to the study of Mozart's symphonies are also presented. The musical incipits have been included to convey the works' identities and are more important for the obscure works than for the well-known ones.
