Rondo form is associated with which label among these options?

• A. Binary
• B. Abacaba
• C. Ternary
• D. Sonata form

Answer: (B)

Rondo form is defined by a main theme that keeps returning between contrasting episodes, creating a sense of unity through repetition. The term Abacaba is used to describe this kind of structure because it highlights the repeated returns of the principal theme around intervening sections. In practice, rondo patterns often feature the recurring theme appearing after each new episode, forming a recognizable refrain. Other forms describe different structures: Binary is a two-part layout, Ternary is a three-part layout, and Sonata form is a larger scheme with exposition, development, and recapitulation, not centered on a repeating refrain.
