what was an important influence in the development of the neoclassical style
Neoclassical architecture Many early 19th-century neoclassical architects were influenced by the drawings and projects of Étienne-Louis Boullée and Claude Nicolas Ledoux. The many graphite drawings of Boullée and his students depict spare geometrical architecture that emulates the eternality of the universe. There are links between Boullée's ideas and Edmund Burke's conception of the sublime. Ledoux addressed the concept of architectural character, maintaining that a building should immediately communicate its function to the viewer: taken literally such ideas give rise to "architecture parlante".
Romantic music One of the first significant applications of the term to music was in 1789, in the Mémoires by the Frenchman André Grétry, but it was E.T.A. Hoffmann who really established the principles of musical romanticism, in a lengthy review of Ludwig van Beethoven's Fifth Symphony published in 1810, and in an 1813 article on Beethoven's instrumental music. In the first of these essays Hoffmann traced the beginnings of musical Romanticism to the later works of Haydn and Mozart. It was Hoffmann's fusion of ideas already associated with the term "Romantic", used in opposition to the restraint and formality of Classical models, that elevated music, and especially instrumental music, to a position of pre-eminence in Romanticism as the art most suited to the expression of emotions. It was also through the writings of Hoffmann and other German authors that German music was brought to the centre of musical Romanticism (Samson 2001).
