Considers the characteristic features of Garífuna music, which are intrinsically related to the history of slavery, warfare, miscegenation, and resistance of this people of African and Caribbean ancestry, living today mainly on the Atlantic Coast of Central America and in the U.S. Based on his analysis of the Wanaragua or Yancunú rhythm, performed in Livingston, Guatemala, by dancers wearing shell rattles (illacu) tied to their ankles, and a musical ensemble consisting of two drums (garaón) and gourd rattles (sisira), the author examines the metric ambiguity of its basic “time line” or 'clave' of 3:3:2 as well as the rhythmic flexibility and unpredictability with which the dancers and musicians relate to it, as a musical expression of the social and cultural conditions created by that history, especially by the processes of miscegenation.
