A lively and highly danceable music style with lyrics, originating in Spain. Characterized mostly by its rhythm, it is generally played with a bolero section in 2/4 time and a clave section in either 6/8 or 3/4 time, although the order of these sections is sometimes reversed. Typically, a guaracha ends with a sensual rumba section. La Negra Tomasa composed in the 1940's, is an interesting (only vocals and percussion), example of this genre. Another example is Corneta sung by Daniel Santos. The guaracha came to Puerto Rico from Cuba in the mid-19th century, and developed into the jíbaro style that most closely approaches contemporary Latin dance rhythms.
