Which style of music did Cojuntos NOT specialize in?

Cojuntos, typically known for their vibrant and rhythmic contributions to music, specialize in a mix of lively dance music and Latin American folk songs, which reflect the cultural and musical traditions of Latin America. This genre is characterized by its upbeat tempos and dance-oriented rhythms, making it a staple in festive and communal gatherings. The focus on traditional African drumming does not align with the core repertoire of Cojuntos, as their music does not primarily emphasize African percussion traditions in the way that option B suggests.

Lively dance music and Latin American folk songs both showcase the lively spirit that Cojuntos aim to embody in their performances, while ballroom jazz standards, though they may share some sonic elements with lively music genres, are distinctively different and more rooted in the jazz tradition rather than the folkloric or dance-focused styles associated with Cojuntos. Thus, the correct answer represents a style that falls outside the specialized expertise and cultural heritage of Cojuntos.
