Answer:
Rap and Rock 'n' roll
Explanation:
Rap: The expression RAP comes from the expression Rhythm And Poetry. This style is so named because it mixes an intense rhythm with poetic rhymes, integrating the cultural scene known as Hip Hop. Born in Jamaica, he has grown into a marketable product among Americans.
Rap developed among the poor in the US, particularly among African Americans and Hispanics, who longed for a sound that reflected their daily life and culture in the early 1970s. In Jamaica in the mid-1960s , the rap gained momentum with the emergence of sound equipment that was arranged outdoors in the ghettos of this country, giving life to the festivals produced on Jamaican streets.
Subsequently, the dances began to have as large scenarios local hitherto used as deposits. These more refined parties not only featured a DJ, but also the intervention of an MC or Master of Ceremonies, also called 'toaster', which incited people with rhyming slogans, usually translating issues of socio-political order, especially controversial topics.
Rock 'n' roll: Rock 'n' roll was born from a mix of various musical styles: rhythm and blues, gospel music, folk music, blues, country and jazz. Before the style became famous, the expression was already found in movies, commercials and music. A good example is the song <em>Rock and Roll Blues</em>, recorded by Erline Harris in 1949.
However, the popularization of the style occurred in the 1950s.
Influenced by a number of predominantly country genres, white musicians such as Carl Perkins, Elvis Presley, Bill Haley and His Comets, and Jerry Lee Lewis began a rock 'n' roll that was christened Rockabilly. Most of Rockabilly's musicians were white, but there were others like Chuck Berry, Little Richards, and Bo Diddley, blacks who came from rhythm and blues. These, while sounding like whites, were not considered to be Rockabilly.
A major label for rock 'n' roll was Sam Philips' Sun Records. In their studios, some of the earliest Rockabilly hits were recorded as Bill Haley and His Comets' Rock Around the Clock and Elvis Presley's "That's All Right (Mama)".
One of the social factors that rock 'n' roll had a lot of influence on was the racial issue. At that time, the US court was taking various measures against racial segregation, but racism was already rooted in American culture. In this scenario, rock 'n' roll was a paradox, because the rhythm was the product of the mixture of black and white rhythms.
