The repertoire files of the late Dr. Barbara Doscher, in which she noted her tips, observations on each particular piece, and notes on how to best teach it, comprise a unique trove of wisdom unmatched by any other source. Laboriously transcribed and annotated by John Nix, one of Doscher's students, the notes are presented here as a companion volume to her best-selling text, The Functional Unity of the Singing Voice. Entries are divided by broad category (art song, arias, folk songs, oratorio, musicals, etc.) and are arranged by song title. Each entry includes author, poet or librettist, key(s) available, ranges (for each key), tessitura, difficulty level, voice types, comments, a summary of the text, and notes as to genre, language, and editions available. Five comprehensive indexes facilitate searching. As a guide to selecting vocal repertoire, this book's practical and sometimes colorful comments on each song or aria will assist the vocal instructor in matching the student's ability and range to the appropriate piece. This distillation of Barbara Doscher's many years of experience in the teaching studio is a necessary addition to any vocal instructor's collection, as well as a valuable resource for the individual singer.
