These nouns mean aesthetic arrangement marked by proper distribution of elements. Proportion is the agreeable relation of parts within a whole: a house with rooms of gracious proportion. Harmony is the pleasing interaction or appropriate combination of elements: the harmony of your facial features. Symmetry and balance both imply an arrangement of parts on either side of a dividing line, but symmetry frequently emphasizes mirror-image correspondence of parts, while balance often suggests dissimilar parts that offset each other harmoniously: flowers planted in perfect symmetry around the pool. “In all perfectly beautiful objects, there is found the opposition of one part to another, and a reciprocal balance” (John Ruskin).
