How did Beethoven expand the role of the coda in his Piano Sonata No. 23 in F Minor?

In Ludwig van Beethoven’s Piano Sonata No. 23 in F Minor (1804–05), commonly known as the Appassionata, he significantly expands the role of the coda beyond its traditional function as a brief concluding section.

While a coda typically serves to round off a movement, Beethoven extends it so substantially that it functions almost as a second development section. This approach is characteristic of his middle period, during which he frequently favored longer developments and codas to explore the logical implications of his thematic material. By treating the coda as a space for further structural expansion rather than just a final cadence, Beethoven elevates the section to a weightier, more integral part of the overall sonata form.12
