A critical-technical anthology for vocal study for Soprano and Tenor. In three parts: Part I (Preparatory Course), Part II (Course of Medium Difficulty), and Part III (Course of High Difficulty).

“This monumental work is both a technical course of vocal development and a selected anthology of vocalises from many singing teachers and composers from the seventeenth through the twentieth centuries...Taken as a whole, these three volumes provide many choices for an entire course of study for the serious classical singer who already has a secure basic technique and is willing to devote the practice time to derive the enormous benefits from this approach.”--Journal of Singing
