What is a primary characteristic of "binary" form in dance?

The primary characteristic of binary form in dance is two contrasting sections. This form is structured around the idea of having two distinct parts that often differ in mood, movement quality, or dynamics. Each section explores different themes or choreographic ideas, providing variety and contrast within the performance. This structure allows for an engaging experience as the audience can observe the shifts in style and expression between the two sections.

The other characteristics mentioned, such as continuous movement or multiple themes, do not align with the definition of binary form, which is specifically about the existence of two separate, contrasting parts. Similarly, while a clear beginning and end can exist in binary form, it is the contrast between the two sections that is essential to its definition.
