Repetition

Repetition is the use of line, color, or a motif, in more than one place in a composition.

Pattern is created through a repetitious use of the same element to create an overall design.

Rhythm is the repeated use of similar elements such as color, line, or shape. Rhythm is also the smooth transition from one part to another.

Motif - Any figure or design, when used either as the central element in a work or is repeated to create an architectural or decorative pattern. Also, a recurrent thematic element in any work.
Composition - The plan, placement or arrangement of the elements of art in a work, usually according to the principles of design. Composition can refer to the area of a sheet in which the design appears in a drawing or print.
Repetitious - This term refers to a way of combining elements of art so that the same elements are used over and over again. Thus, a certain color or shape might be used several times in the same picture.
Elements - The basic components (line, value, form, space, color, space, shape, and texture) used by the artist when producing works of art.
Shape - An element of art, it is an enclosed space defined and determined by other art elements such as line, value, color, and texture. In painting and drawing, shapes may take on the appearance of solid three-dimensional objects even though they are limited to two dimensions - length and width. This two dimensional character of shape distinguishes it from form, which has depth as well as length and width.
