THREE AND FOUR-ACT STRUCTURES SIDE-BY-SIDE

The Dramatica three-act structure and four-act structure are two different ways to look at the same material; two different contexts by which we can understand the quad form.

Example 4A-3: Three-Act Structure

1	2	3
(1–2)	(2–3)	(3–4)

Example 4A-4: Four-Act Structure

…and…

Example 4B-3: Three-Act Structure

1	2	3
(1–2)	(2–3)	(3–4)

Example 4B-4: Four-Act Structure

If we look at the examples in both forms next to one another, there are some observations that can be made:

• Four-act structure appears clearly defined, almost compartmentalized.
• Three-act structure appears fluid, almost lacking definition.

If we abstract a little bit, we can take this one step further:

• Four-act structure seems more appropriate to a "linear" viewpoint, a place where seeing the arrangement of the acts as separate "steps" is clearest.
• Three-act structure seems more appropriate to an "holistic" viewpoint, a place where seeing the ebb and flow of the acts is clearest.

As a generalization, Dramatica takes this another step further:

• Four-act structure provides a context within which determining the arrangement of the quad components is clear and direct, but obscures the experiential "meaning" of the arrangement.
• Three-act structure provides a context within which the meaning of the arrangement comes out of the flow of the quad components from one to another, but obscures the ability to predict the arrangement of the components.

In theory, you can develop a story using only the three-act structure or the four-act structure. Practically speaking, however, it is often more beneficial to use both. Using both structural forms lets a writer take advantage of each form's strengths while minimizing their weaknesses.
