Which dance style combines elements from different dance forms and focuses on a simple forward/backward sequence?

The style that truly embodies a combination of elements from various dance forms while emphasizing a straightforward forward and backward movement is the Foxtrot. This dance originated in the early 20th century and is characterized by its smooth, flowing movements which involve a basic step pattern that can easily be learned and performed by beginners. The Foxtrot incorporates influences from ragtime music and other dance styles, allowing dancers to express themselves through variations in rhythm and style while still maintaining a foundational sequence.

Other dance styles, while distinct in their own right, do not primarily focus on the same level of blending and simplicity in sequences. Cumbia, for instance, has its roots in Colombian folk music and features a different rhythmic structure and dance style. Tango, known for its intricate footwork and dramatic poses, requires a level of intimacy and connection that does not emphasize simple forward and backward movements. Bossa Nova, on the other hand, is a Brazilian music genre and dance style which includes a more relaxed and flowing rhythm, but does not primarily focus on a straightforward dance sequence like the Foxtrot. Therefore, the essence of the Foxtrot's integration of diverse dance influences and its straightforward movement pattern makes it the correct choice in this context.
