Similarities in Music
If you look back at the origins of both bachata from the Dominican Republic, and Bomba from Puerto Rico you see that both forms of Spanish music came from the lower-class population of the country as a form of expression based on heartache and pain. They’re also similar in the fact that they both were kind of viewed as lower forms of music domestically. In both cases its known that the upper-class citizens frowned upon those in the genres and didn’t give any of them notoriety at first.
There are also some similarities in Merengue from Dominican Republic and Plena in Puerto Rico in that they both were more socially accepted in their respective countries. Also, the melodies of merengue and plena are upbeat and have fast arraignments. They also both use many similar instruments such as drums, guitars and some brass instruments such as the guiro and horns in some cases. They are both very pleasant to listen to and they make you want to literally get up and dance. What’s very evident in Spanish culture as in American culture is that Latin America takes their music very seriously and use it as an expression of self as we do here in the United States.
