The concept of “rules of art” is old, respected and is a requirement for such art as the Haiku, the Sonnet, the Fugue and just for fun, the Limerick and the “one liner“ joke. Every one of these artistic forms of expression is governed by a strict adherence to form and rules. Yet in spite of “restrictive rules of art,” artists continue to solve the problem of creative expression. The problem of creating within a framework places more responsibility on the creator, giving him (or her) the responsibility of constructing their art within a set of rules.
I do not advocate a slavish adherence to “rules of art.” One should learn what they are, how and when they can be used effectively and how they can help you create a coherent image. Learn the rules first. Demonstrate that you can abide by them.
Then, if the situation requires it, go out and smash them with impunity if it helps you deliver your message to the audience.
