Composition is how the artist directs your eye. All formal elements are part of an image's composition. The artist carefully balances these elements to reach their desired goal, whether that goal is to inspire, provoke thought, energize or simply to create beauty.
An image's composition will accent a room in different ways. The lines of an image, for example, subconsciously sets a tone within a room. Horizontal lines often evoke serenity and peace. Images such as a sunset, a beach scene, a person reclining or laying down all have strong horizontal lines. Vertical lines evoke vitality, energy and progress. Think of a towering tree, a high-rise building, or a horse and rider.
Ask yourself what’s the purpose of the room? Is this a room where I am cooking, relaxing, watching television, entertaining, studying, etc? Do you want to create some vitality, serenity, or even self-contemplation? When you know the answers to these typical questions, finding artwork to match becomes meaningful.
