Structure is an arrangement of parts according either to complex or simple design, pattern or organization. Complex structures: fugue, sonata, serial form, indeterminate statics of concrete frame, desoxyribose nucleic acid molecule. Simple structures: continuous crescendo, pivot support beam, helium molecule, So Sho painting, Haiku, held tone, etc.
Monomorphic structure (having a single, simple form; exhibiting essentially one structural pattern) Neo-Haiku. This monomorphism tends to border on Concept-art, since it emphasizes an image or idea of generalization from particulars rather than particularization (arrangement into particular design or pattern) of generalities. In Concept-art realization of form is therefore irrelevant, since it is an art of which the material is concepts (closely bound with language), rather than particular form of film, sound, etc.
