Form is the organization of all the elements of design and principles of design to present the subject matter in a way that communicates the artist's intended content. This means that several artists can create works that contain the same subject matter, but that each will potentially have a different meaning. If an artist paints a rose the rose is the subject matter, but how that artist paints it will be unique. That uniqueness is determined through the choice of elements and principles and how much of each is used. Even when subject matter does not exist, as in nonobjective works, form is still present. In nonobjective works the form becomes the content. Although form in works that have a serial aspect is perceived a little differently, the same basic structural considerations apply. In many of these works the type of form is used to identify the work - a symphony, a musical, a ballet, an epic film, etcetera.
