Repetition is the use of duplication or a repeat of the same pattern, object, color, or design. When using repetition, the artist has to keep harmony, balance, and proportion in mind that’s where variation or variety comes in. Variety is one of the artist devices that make up the principle of design. Its commonly used when the repetition is used; because to much repetition can cancel out the principle of harmony and with to much variety the point, whether it be focal or point of view, the artist attempts to make in the art work can either be to much and/or not clear. So that’s why variety and repetition are used together, they kind of have a cohesive relationship. What one principle lacks the other one makes up for it and vise versa.
