Impressionism, French Impressionnisme, a major movement, first in painting and later in music, that developed chiefly in France during the late 19th and early 20th centuries. Impressionist painting comprises the work produced between about 1867 and 1886 by a group of artists who shared a set of related approaches and techniques. The most conspicuous characteristic of Impressionism in painting was an attempt to accurately and objectively record visual reality in terms of transient effects of light and colour. In music, it was to convey an idea or affect through a wash of sound rather than a strict formal structure.
