"Entries are divided by broad category (art song, arias, folk songs, oratorio, musicals, etc.) and arranged alphabetically 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."--BOOK JACKET.
