Why would an artist choose to use harmony in a piece of artwork?

An artist would choose to use harmony in a piece of artwork primarily **to give a feeling within the piece that all elements are working together in a similar manner**. Harmony helps to create a sense of unity and coherence among the different components of the artwork, allowing viewers to perceive the piece as a cohesive whole rather than a collection of disparate parts. This can enhance the overall emotional impact of the artwork and contribute to its aesthetic pleasure.
