Modern art is a vast term that encompasses many different styles and forms of artistic expression that emerged during the late 19th and early 20th centuries. Some synonyms for modern art include contemporary art, abstract art, avant-garde art, postmodern art, and experimental art. Contemporary art refers to art created in the present day, whereas abstract art is focused on the use of color, line, and form rather than representation. Avant-garde art is innovative and experimental, while postmodern art seeks to challenge traditional artistic conventions. Experimental art, on the other hand, involves a process of trial and error, where artists experiment with new techniques and materials to create unique works of art.
