Two basic considerations we need to be acquainted with are form: the physical and visible characteristics inherent in works of art, and content: the meaning we derive from them. Formal distinctions include a work’s size, medium (painting, drawing, sculpture or other kind of work) and descriptions of compositional elements such as the lines, shapes and colors involved. Issues of content include any visual clues that provide an understanding of what the art tells us. Sometimes an artwork’s content is vague or hidden and needs more information than is present in the work itself. Ultimately these two terms are roped together in the climb to understand what art has to offer us.
