Did romantic composers maintain the form of the earlier periods?

Romantic composers often retained some forms from earlier periods, such as sonatas, symphonies, and concertos, but they frequently expanded and transformed these structures to express deeper emotions and personal themes. They introduced greater freedom in form, allowing for more improvisation and innovation, which led to the development of new genres like the art song and tone poem. While the foundation of classical forms remained, the Romantic era emphasized individual expression and emotional depth, marking a departure from strict adherence to traditional structures.
