Impressionism was primarily a visual art movement begun by a group of artists in France who started exhibiting their work in the 1860s. The Impressionist style shows the effects of light and atmospheric conditions in artworks that spontaneously capture a moment of time. Music was the only other art form that most emulated the ideas of Impressionism. Post-Impressionism was a movement or style exclusive to visual art. Post-Impressionists used the art elements to express reality in different ways, expanding the ideas of Impressionism while rejecting the limitations. Three Post-Impressionists—Gauguin, van Gogh, and Matisse—have been credited with starting modern art.
