Sequence Method (8 Sequences)
Structure
ACT ONE
Sequence 1: Status Quo & Catalyst

Aristotle's Six Components
The foundational elements of drama (per Aristotle):
- Plot: The arrangement of events or incidents
- Characters: Provide motivation, plot, and conflict
- Language: Dialogue (both dramatic and narrative)
- Themes: Thought and ideas behind the story
- Rhythm: Music/mood (the emotional pacing)
- Spectacle: The set, costumes, and special effects
The Greeks' Essential Truth: A show or scene must have a beginning, middle, and end.
- Beginning: Protagonist lives a good life but has a great character flaw
- End of Beginning: Reversal of fortune brought on by the flaw
- Middle: Protagonist fights change but recognizes error, changes from ignorance to knowledge (too late)
- End: Catastrophe brings suffering, resulting in soul cleansing (catharsis)

- Strong Midpoint
- All Is Lost moment exists
- Theme stated and proven
