Rhythm: Rhythm can be described as timed movement through space; an easy, connected path along which the eye follows a regular arrangement of motifs. The presence of rhythm creates predictability and order in a composition. Rhythm depends largely upon the elements of pattern and movement to achieve its effects.
Pattern: Pattern uses the art elements in planned or random repetitions to enhance surfaces of paintings or sculptures. Patterns often occur in nature, and artists use similar repeated motifs to create pattern in their work. Pattern increases visual excitement by enriching surface interest.
