According to the formalist theories, what characterizes the work of art is its form and not its representative character. What characterizes the fine arts and perhaps music is the presence of the significant form. The concept of significant form is simple and cannot be defined.
What makes the uniqueness of a painting is the unexpected harmony between the pure colors, the shapes and dimensions of its forms, which must constitute a significant way. Characteristic of the significant form is that it produces an aesthetic emotion in art-sensitive people.
