Repetition in Nature
Repetition in nature is a common sight, from schools of fish to forests of trees, patterns of leaves to spores on a mushroom. The important thing to notice with natural repetition is the presence of variation.
The examples of natural repetition in the images below also exhibit variation.
Due to constant exposure, our hard wired response is to always expect repetition to be accompanied by variation. When the variation is missing, repetition becomes monotonous.
The repeating shapes, without variation, in the image below, can be taken in with one glance. The brain comprehends one and immediately knows the rest are identical.
When variation is introduced, sub conscience mental activity is required to absorb the repeating elements. This relieves monotony and adds interest even when the variation is subtle. It causes the viewer to subconsciously engage with the work.
Repetition without variation becomes pattern and moves more into the realm of what was considered decorative art. That said, many of the pop artists incorporated pattern into fine art, a trend that has continued into the contemporary art practice of today. (1)
Paul Klees painting, “Heroic Strokes of the Bow”, features a progression of repeating arcs and lines that criss-cross their way down the painting. Variation in length, thickness and angle echo the movement of a violin bow as it rises and falls through a piece of music. A series of dots, squares, circles and dashes are woven through the movement of the repeating arcs and lines suggesting a percussive accompaniment to the rhythm of the bow.
Breaking the RhythmEarly experiments in industrial psychology found that injuries to operators of repetitive machinery (punches, drill machines etc.) could be reduced by rotating operators after a certain length of time. ‘Apparently the human organism finds repetitive motion boring if experienced for too long and resists by breaking the rhythm.'(2)
The photograph below demonstrates the importance of variation in repeating elements. If all the windows were the same the image would be just a monotonous facade, but because no two windows are the same there is a satisfaction in scanning the surface and comprehending the changes
If you are using repeating elements as an area of relief in a design, variation is not necessary. If the repeating elements are to add to the interest of a design or painting, variation is important.
