what is rhythm
Rhythm, in art, is a visual beat. A pattern has rhythm, but not all rhythm is patterned. For example, the colors of a piece can convey rhythm, by making your eyes travel from one component to another. Lines can produce rhythm by implying movement. Forms, too, can cause rhythm by the ways in which they’re placed one next to the other.
What is repetition
Repetition refers to one object or shape repeated; pattern is a combination of elements or shapes repeated in a recurring and regular arrangement.
What is movement
Is the path the viewer’s eye takes through the artwork, often to a focal area. It can be directed along lines, edges, shapes and color. Movement is closely tied to rhythm.
What is balance
Balance is the concept of visual equilibrium, and relates to our physical sense of balance. It is a reconciliation of opposing forces in a composition that results in visual stability. Most successful compositions achieve balance in one of two ways: symmetrically or asymmetrically. Balance in a three dimensional object is easy to understand; if balance isn’t achieved, the object tips over. To understand balance in a two dimensional composition, we must use our imaginations to carry this three dimensional analogy forward to the flat surface.
What is proportion
Proportion refers to the relative size and scale of the various elements in a design. The issue is the relationship between objects, or parts, of a whole. This means that it is necessary to discuss proportion in terms of the context or standard used to determine proportions.
- What is variety
Variety is a principle of design that refers to a way of combining visual elements to achieve intricate and complex relationships. It is a technique used by artists who wish to increase the visual interest of their work. Artwork that makes use of many different hues, values, lines, textures, and shapes reflects variety. Keeping the same size while changing the color can also show variety.

What is harmony
Harmony in art and design is the visually satisfying effect of combining similar, related elements. For instance: adjacent colors on the color wheel, similar shapes etc.
What is unity
unity occurs when all of the elements of a piece combine to make a balanced, harmonious, complete whole. Unity is another of those hard-to-describe art terms but, when it’s present, your eye and brain are pleased to see it.
