Unification Thought’s Theory of Art asserts that all artistic activity is an activity of unification. “Art is the unity of various correlative activities and elements in creating beauty.” These correlative activities are described as:
- Unity of Creation and Appreciation
- Unity of Content and Form
- Unity of Universality and Individuality
Internally, art can induce transcendent and consciousness-changing conditions in which cultural and social barriers can be overcome thus contributing to a condition in which understanding and appreciation can more readily occur. Externally, art can harmonize diverse techniques and styles in ways that allow for greater appreciation of various cultural influences. This appreciation can also contribute conditions for harmonization and is concomitant with Unification Thought's Principle of Appreciation.
Dr. Sun Myung Moon has asserted that music of the “New Age" should be predicated on tonal/classical musical attributes while incorporating “Abel-type” aspects of other styles or ethnic influences. In so doing a greater appreciation of “the other” can occur and a more universal musical expression can be formulated.
The nineteenth century Romantic period was the great age of program music wherein composers were imbued with the concept of unifying the arts such as wanting their musical pieces to be poetic as well as poets wanting their poems to be musical. Program music was written to be associated with a poem, story, scene or idea, and such music brought out emotions, events or even sounds from a particular environment.
As composers of the Romantic period looked to literary and folk influences as inspiration for their creativity
, it spawned numerous compositions based on the literature, legends, folklore, history and mythology of their native countries. Composers such as Dvorak, Smetana, Liszt, Rimsky-Korsakoff, Grieg and Respighi based a number of their works on these particular influences. This in turn led composers to utilize folk music in their compositions on occasion. Thus the juxtaposition of folk idioms (content) and "classical" conventions (form), is realization of the Unification Principle of Content and Form.
