Rumba is a secular genre of Cuban music involving dance, percussion, and song. It originated in the northern regions of Cuba, mainly in urban Havana and Matanzas, during the late 19th century. It is based on African music and dance traditions, namely Abakuá and yuka, as well as the Spanish-based "coros de clave". According to Argeliers León, rumba is one of the major "genre complexes" of Cuban music, and the term rumba complex is now commonly used by musicologists. This complex encompasses the three traditional forms of rumba (yambú, guaguancó and columbia), as well as their contemporary derivatives and other minor styles.
