Since earlier research revealed a general scarcity of song materials, this annotated bibliography of vocal music composed for elementary children's voices by a number of distinguished 19th and 20th century composers was compiled. Correspondence with contemporary composers served as a main source of data but composers' biographies, music dictionaries and periodicals, publishers' catalogs, and lists of published music were also used. Over 500 titles of songs are arranged alphabetically, first by composer and then alphabetically under each composer by title. The original compositions vary from four measures of very easy melodies to long musical forms of considerable difficulty written for professionally trained choirs, and from functional, diatonic styles to avant garde and expressionistic styles. In order to assist users in determining appropriate compositions for their groups, analytical annotations include information on musical and textual characteristics, and each composition has been assigned a ranking of difficulty using a scale of five degrees. Information on textual source, language, content, and publication is provided. (SJM)
