Reviewing the first volume of Opera Scenes for Class and Stage, Walter Ducloux wrote in the Opera Journal: If you can come up, within five seconds, with an operatic excerpt involving two sopranos, four mezzo-sopranos, two tenors, and a bass, you don't need this book. Otherwise hurry and buy it. I keep it on my night table.
In More Opera Scenes, the Wallaces have reviewed 100 additional operas and have chosen over 700 scenes. The popular Table of Voice Categories providing more than 300 combinations is also featured in this volume.
