What is Rondo form?

Rondo form is characterized by a recurring theme that alternates with different sections, creating a structure that provides contrast and variety. The classic structure of a Rondo is typically seen as ABACA, where "A" represents the main theme that repeats, while "B" and "C" are contrasting sections that provide musical variation.

In this form, the return of the "A" section helps to unify the composition, while the interspersed contrasting sections keep the listener engaged. This alternating pattern is what distinguishes a Rondo from other musical forms. The repetition of the main theme after contrasting material is a key feature that defines this structure. Therefore, the answer reflecting the ABACA format accurately captures the essence of Rondo form.
