Final answer:
Xavier Cugat brought Latin music to the mainstream.
Step-by-step explanation:
The element that Xavier Cugat brought to the mainstream is Latin music. Rock and roll was a genre that emerged in the 1950s, combining elements of gospel, blues, country, jazz, and R&B. While rock and roll had a significant impact on American culture, Latin music was not the element that Xavier Cugat brought to the mainstream.
Latin music refers to a wide range of musical styles that originate from Latin America, including genres such as salsa, merengue, and bossa nova. Xavier Cugat, a musician and bandleader, popularized Latin music in the United States during the mid-20th century, incorporating it into his performances and recordings. His energetic and rhythmic interpretations of Latin music helped to introduce it to a wider audience and played a significant role in bringing Latin music to the mainstream.
