This wonderful book has served me well in teaching high school students about the wonders of opera and how to appreciate this complex art form. DiGaetani's book contains succinct, self-contained chapters on the history of opera, the operatic voice, famous singers through the centuries, opera conducting, and opera as theatre. His brief yet pungent summaries of the principal operas in the modern repertoire are especially good. Additionally, the glossary of terms in the back of the book has been carefully selected not to overwhelm the neophyte while still providing complete, accurate definitions. Having taught opera appreciation for several years using only this book, I know how 'User Friendly' it is. I keep coming back to it year after year because it is so expertly crafted. Anyone who wants an introduction that is both comprehensive and accessible will find this book to be indispensable. Without question, a "Best Buy" for the price and length!
