The singing of capeyuye (the Mascogo—Black Seminole people—equivalent of the U.S. spiritual) became a significant token of individual and communal identity in that population. The life and career of Gertrudis Vázquez are studied as emblematic of that tradition. The technical aspects of capeyuye are described and its performance is examined with the context of Mascogo society, particularly its connection with important events such as funerals, birthdays, and other festive occasions.
