With the assumption that the teacher of students with identifiable ethnic or cultural background must be prepared to deal with each student's heritage in a meaningful way, the document provides resource materials for Connecticut classroom teachers and/or music specialists with responsibilities for teaching children of Puerto Rican heritage. The materials enable the sensitive teacher to use the opportunities for cultural and musical understanding provided by Puerto Rican holidays and festivals to enrich classroom work, and to work from the interests of Hispanic students, developing self-concepts and familiarizing those of Hispanic origins with aspects of their own heritage which may not be known to them. The document supplies: a brief history of Puerto Rico and Puerto Rican music; descriptions and drawings of popular musical instruments (guiro, maracas, caracol, drum or maguey, cuatro, tiple, bordonua, tres, guitar, bomba drums, congas, clave, pandereta, timbales, bongo drums, cencerro, and tambora); biographical sketches of 14 Puerto Rican composers; description and step diagrams of dances (La Danza, La Bomba, La Plena, and El Seis); examples of musical forms (Decima and Aguinaldos); and selected Puerto Rican music.
