Consists of Brazilian sheet music from the period, ca. 1915-1945, many pieces bearing the stamp "Almirante" indicating the collection was originally amassed by Henrique F.D. Almirante (b. 1908), Brazilian singer, composer, scholar and collector active professionally in the 1930s-1950s. Publications from Casa Napoleao predominate. Consists largely of popular piano music or voice and piano editions, but also includes several works for violin and a few manuscript items. Includes dance music of the 1920s and 1930s, as well as works connected with Carnival festivities.
Also contains popular Argentine sheet music from the same time period, as well as popular Cuban sheet music from the 1960s.
Brazilian and Argentine collection acquired by Everett Helm sometime in the 1950s. Provenance of Cuban sheet music is unknown. Purchased by the University of Illinois Library from Tulane University's Inter-American Center for Musical Research in the late 1960s by librarian William M. McClellan, under the advice of ethnomusicologist Gerard Behague for Behague to use the collection for his research into the history of Brazilian Music. Only a portion of the Helm collection was acquired by the library to meet Behague's research needs.
