Rondo
A form built on a main theme that returns between contrasting episodes, typically in the pattern ABACA or ABACABA.
Also called: Rondo form
Rondo is a form in which a main theme, A, returns between contrasting episodes. ABACA is the common five-part pattern, and ABACABA adds a seventh section. The returns of the refrain give the form its stability, while the episodes provide contrast in key, texture and character. Rondos often end with a coda that restates the refrain for a final affirmation. In C major, the refrain might be an eight-bar theme in C, with episodes in G and in A minor, each followed by a return to C. Classical finales are often rondos, and the form is widely used in finale movements of sonatas and concertos.
