“As a child, Frances Densmore (1867– 1957) developed an appreciation of music by listening to the nearby Dakota Indians.
“Densmore began recording music officially for the Smithsonian Institution’s Bureau of American Ethnology (BAE) in 1907. She worked with the Chippewa, the Mandan, Hidatsa, the Sioux, the northern Pawnee of Oklahoma, the Papago of Arizona, Indians of Washington and British Columbia, Winnebago and Menominee of Wisconsin, Pueblo Indians of the southwest, the Seminoles of Florida, and the Kuna Indians of Panama.”
