Final answer:
Enlightenment art, including music and sculpture, favored Neoclassical styles with an emphasis on harmony, proportion, and morality, contrasting with the earlier Rococo period. Literature from influential thinkers challenged traditional authority and advocated for reason and individualism, and classical music saw the refinement of symphonies and quartets.
Step-by-step explanation:
Enlightenment Art and Literature
Enlightenment art and literature were deeply interwoven with the intellectual currents of the 18th century, featuring a remarkable shift towards reason, empiricism, and a critique of traditional structures such as the monarchy. In the realm of the visual arts, this period saw a departure from the ornateness of Rococo towards Neoclassical art which embraced antiquity's ideals of harmony and proportion. Works of art from this period sought to instill moral values, thus rejecting the perceived immorality of earlier styles. The sculpture looked back to classical antiquity, favoring more direct and refined forms over the elaborate Baroque styles.
In terms of literature, Enlightenment thinkers like Voltaire, Rousseau, Montesquieu, and Diderot used their essays, plays, and philosophical writings to challenge established norms and to promote principles of individualism and rationality. Meanwhile, in music, this intellectual awakening gave rise to classical music, with composers such as Mozart and Haydn refining genres like the symphony and quartet, emphasizing form and balanced structure in their compositions. The overarching ethos of Enlightenment art and literature was to serve as both a reflection and a catalyst for progress, exemplifying the spirit of questioning and advancement that characterized the era.
