On the other hand, there are also music genres Dominican widespread across the country, whose origin is uncertain, being considered of Spanish and African origin, depending of musicologists and historians. Such is the case of the merengue music. So, Luis Alberti, one of the musicians considered as fathers of merengue, thinks that the roots of this music genre are purely Spanish. F. Lizardo, Dominican folklorist, by contrast, thinks that this origin is in the Bara tribe of Madagascar, who came to the island in the eighteenth century and brought a dance called "merengue" that has spread throughout the Caribbean. A very similar pace, adds Lizardo, arrived today with the Yoruba of Dahomey. In the African polyrhythm was also the merengue. Also often linked to the origin of merengue a dance called URPA or UPA, a native of Havana and arrived in the Dominican Republic between 1838 and 1849. The dance sailed through the Caribbean coming to Puerto Rico where he was well received. One of the movements of this dance is called "merengue" which apparently is the way selected to call the dance, and came to the Dominican Republic where he evolved into the genre of merengue. However, the Cuban UPA is also a dance whose origin appears to be in West Africa. In fact, in early ls, despite its rise among the masses, the upper class did not accept the merengue for long, because apparently, their connection with African music. Another cause that weighed on the repudiation and attacks the merengue were literary texts that accompany it, usually risqué.
