The Classical Rondo form is based on the presentation of a principal theme (A), with contrasting material (B, or C, or D) in a different key called an episode occurring between statements of the principal theme in the original key. First Rondo has three parts, A-B-A, and is basically ternary. Second Rondo has five parts, usually A-B-A-C-A. Third Rondo has seven parts, usually A-B-A-C-A-B-A. Each of the episodes, or digressions, is typically in a different key and introduces a contrasting thematic idea.
Composers often employed modulatory transitions between sections of the Rondo form, as well as a brief coda or codetta at the end. Like the Minuet and Trio, the Rondo was commonly used in multimovement instrumental works from the Classical period.
