Book excerpt: Musically sound and fully annotated, this new reference work provides ready access to over 700 excerpts from 100 operas, by voice categories, and thus provides information on a wide variety of matters of interest to directors, teachers, and singers. A table of voice categories, coded excerpts (including length and reference to accessible scores), character descriptions (including estimations of degrees of difficulty of the music), summaries of the action of each excerpt, and indexes to titles, composers, and well-known arias and ensembles make this book an indispensable tool.
