Explain the development of genre realism and Neoclassicism as stylistic alternatives to the Rococo

What will be an ideal response?

The Rococo style, in its elegance and luxuriousness, did not appeal to everyone. Diderot, for example, denounced Rococo boudoir imagery and demanded an art that made "virtue attractive and vice odious." Both genre painting and Neoclassical works provided an alternative stylistic framework for artists.
Genre artists focused instead on scenes of everyday life and behavior among the middle and lower classes. Genre painting reflected the growing interest in middle-class tastes and values, as well as the popular fascination with the "modern moral subjects" that dominated the contemporary novel, the journal, and the theater. Painters, such as Jean-Baptiste Greuze, exalted the natural virtues of ordinary people and brought to life moralizing subjects.
Neoclassicism looked to the ancient Greco-Roman world for inspiration. In those ancient principles of symmetry, balance, and restraint, artists found a way to manifest the Enlightenment ideals of reason, clarity, and order. Neoclassicism equated beauty with goodness, virtue, and truth. In painting, sculpture, and music, artists embraced this style as a reaction to the illusionistic theatricality of the Baroque style and the fantasy of the Rococo style.
