In the visual arts, composition is the placement or arrangement of visual elements or 'ingredients' in a work of art, as distinct from the subject. It can also be thought of as the organization of the elements of art according to the principles of art.
The composition of a picture is different from its subject, what is depicted, whether a moment from a story, a person or a place. Many subjects, for example Saint George and the Dragon, are often portrayed in art, but using a great range of compositions even though the two figures are typically the only ones shown.
The term composition means 'putting together' and can apply to any work of art, from music to writing to photography, that is arranged using conscious thought. In the visual arts, composition is often used interchangeably with various terms such as design, form, visual ordering, or formal structure, depending on the context. In graphic design for press and desktop publishing, composition is commonly referred to as page layout.
