The root word of repetition is “repeat”. When you repeat a certain size, or shape or color you add strength to the overall image. Repetition is a basic concept in the world of art. If you want to make a statement, you repeat certain elements again and again. If you repeat something once or twice it becomes more interesting. If you repeat something many times it becomes a pattern and takes on a life of its own. Patterns give us order in an otherwise chaotic world. There’s something fundamentally pleasing about seeing order in such a way that we know what to expect. In most cases, repetition is a tool used to calm the viewer, making them feel comfortable and at peace while enjoying the view.
