Impressionism definition

A theory or style of painting originating and developed in France during the 1870s, characterized by concentration on the immediate visual impression produced by a scene and by the use of unmixed primary colors and small strokes to simulate actual reflected light.

A literary style characterized by the use of details and mental associations to evoke subjective and sensory impressions rather than the re-creation of objective reality.

(music) A style of art music of the late 1800s and early 1900s, often evoking a dreamy mood and characterized by modal or whole-tone scales, rich and often dissonant harmonies in unconventional progressions, and the avoidance of traditional forms.

A theory and school of painting exemplified chiefly by Monet, Pissarro, and Sisley, but also by Manet, Renoir, etc., whose chief aim is to capture a momentary glimpse of a subject, esp. to reproduce the changing effects of light by applying paint to canvas in short strokes of pure color.
