Designed particularly as a reference work for opera producers, students, performers, and writers, this book provides basic production information about more than 500 operas. Anyone planning to produce an opera will find here the essential information he needs in order to judge whether a given opera is appropriate to his resources for production. Information for individual operas is given concerning the number and importance of settings; size of orchestra, chorus, and ballet; number of singers, their relative importance and individual requirements; sources for obtaining musical materials' previous performances in America; and the opera story, its period, and composer. Extensive information about 150 full-length operas and 109 short operas is provided, with supplementary information about more than 260 other operas. The operas are alphabetized by title for easy reference. In order to condense the information as much as possible, codes and abbreviations are used, with keys and indexes at the back of the book. This book will be invaluable to those working in either amateur or professional companies, in opera workshops, in school, college, or civic opera groups. Those whose interest in opera is confined to the other side of the footlights will find the book absorbing, too, just as a glimpse backstage would be.
