The term form can mean several different things in art; form is one of the seven Elements of Art and connotes a three-dimensional object in space; a formal analysis of a work of art describes how the elements and principles of art work together
When used in tandem with the word art as in art form, it can also mean a medium of artistic expression recognized as fine art or an unconventional medium done so well, adroitly, or creatively as to elevate it to the level of a fine art.
AN ELEMENT OF ART
Form is one of the seven Elements of Art, which are the visual tools that an artist uses to compose a work of art. In addition to form, they include: line, shape, value, color, texture, and space. As an Element of Art, form connotes something that is three-dimensional and encloses volume, having length, width, and height, versus shape, which is two-dimensional, or flat. A form is a shape in three dimensions, and, like shapes, can be geometric or organic.
