This site introduces unknown Emanuel Bach (C. P. E. Bach).
The following text is a response from ChatGPT to the question: "Are there examples where ritornello form was used in sonatas or symphonies?"
Ritornello Form is primarily a structure used in Baroque concertos, but elements of this form were incorporated into sonatas and symphonies from the mid-18th century onwards. However, rather than being used in its original form, its structure and concept of repetition were creatively adapted.
Examples of Ritornello Form Usage
Carl Philipp Emanuel BachEmanuel Bach applied the ritornello form from concertos to his keyboard sonatas and symphonies. In his symphonies (e.g., Symphony Wq. 183, No. 1), sections where the main theme is repeated in a ritornello-like manner can be observed. Particularly in the first movement, the orchestral presentation of the main theme, which is later restated in different keys, demonstrates the influence of ritornello form.
Johann Christian BachJohann Christian Bach also incorporated elements of ritornello form in his keyboard sonatas and symphonies. His symphonies and piano concertos feature orchestral presentations of themes and dialogic repetitions across different sections, reflecting the ritornello structure.
The Fusion of Ritornello Form and Classical Style
Joseph HaydnHaydnʼs symphonies exhibit ritornello-like repetition and dialogue, particularly in finale movements where themes reappear while episodic development occurs, reminiscent of ritornello form.
Example:
Mozartʼs symphonies and piano concertos also display elements of ritornello form. His piano concertos, in particular, blend the sonata formʼs double exposition with ritornello structure, where themes are repeated between the orchestra and the soloist.

The Influence of Ritornello Form
Ritornello form significantly influenced the development of Classical sonata and rondo forms. In sonatas and symphonies, the use of key changes and thematic repetition clearly reflects elements inherited from ritornello form. Additionally, the free development of material in ritornello episodes shares similarities with the manipulative techniques used in the development sections of sonata form.
Conclusion
Although ritornello form itself was rarely used directly in sonatas and symphonies, its structural concepts of thematic repetition and development were adopted by late 18th-century composers. Composers such as Emanuel Bach, Johann Christian Bach, Haydn, and Mozart uniquely evolved the principles of ritornello form and applied them to diverse Classical music forms.
