(Note: there is overlap with what is considered "contemporary," "postmodern," and "modern art.")
Modern Art is a term that refers to artistic works produced during the period extending roughly from the 1860s through the 1970s, and denotes the style and philosophy of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation. Modern artists experimented with new ways of seeing, and with fresh ideas about the nature of materials and functions of art.
