What musical form combines elements of sonata and rondo form, typically structured as ABACABA?

The musical form that combines elements of both sonata and rondo forms is known as sonata-rondo form. This structure is characterized by its distinctive pattern of sections, typically arranged as ABACABA.

In this form, the A sections represent the recurring theme, similar to the refrain of a rondo, while the B and C sections provide contrasting material that introduces new themes and harmonies, drawing from the development style found in sonata form. The framework allows for thematic development and variation, providing a richer, more complex narrative within the music than what is usually found in pure rondo or sonata forms.

In contrast, the other options do not capture the specific combination of elements that define sonata-rondo form. A fugue, for example, is centered around the intricate interplay of themes and counterpoint but does not follow the ABACABA structure. A suite consists of a collection of dance movements, and a symphonic poem is typically a free-form piece designed to evoke a specific story or image, neither of which aligns with the structured interplay of sonata and rondo that characterizes sonata-rondo form.
