If you don't already know the names Amy Marcy Cheney Beach, Dudley Buck, or William W. Gilchrist, this website will certainly pique one's interest. Associated with 19th and 20th century American choral music, information on these persons (and others) can be found on the American Choral Music site. This online collection is a joint collaboration between the American Choral Directors Association and the Library of Congress. In a nutshell, the site contains choral music from the public domain that users can download, along with information on the composers and material on each work's historical context and stylistic features. Currently, the site contains 28 full-length works which include Dudley Buck's "Festival Hymn" (written for the 1872 Peace Jubilee in Boston) and Amy Beach's "Festival Jubilate", which was composed for the 1893 World's Columbian Exposition in Chicago. Of course, that's not all as users can also make use of Horatio W. Parker's "Bow Down Thine Ear" and George W. Chadwick's "Elfin Song".
