||
## Overview
|
||
Three-Act Structure(三幕式)是西方叙事中最经典的戏剧结构模型,将叙事分为 Setup(建置)、Confrontation(对抗)和 Resolution(解决)三个部分。该结构可追溯到 Aristotle 的《诗学》,在现代由 [[Robert McKee]]、Syd Field 等人系统化为编剧标准。
|
||
|
||
## Act Breakdown
|
||
|
||
### Act I — Setup(约占全剧 25%)
|
||
- 建立 Ordinary World(日常世界)
|
||
- 引入主角
|
||
- 建立 Status Quo(现状)
|
||
- Inciting Incident(触发事件)打破平衡
|
||
- Act Climax:主角必须做出选择/行动
|
||
- Act Break:不可逆的决定
|
||
|
||
### Act II — Confrontation(约占全剧 50%)
|
||
- Rising Action(上升动作)
|
||
- 阻力递增(complications, obstacles, setbacks)
|
||
- Midpoint Shift(midpoint reversal 或 midpoint revelation)
|
||
- 叙事债务逐渐积累
|
||
- 主角的 lie/belief 受到考验
|
||
- Dark Night of the Soul(最低点)
|
||
- Act Break:危机揭示
|
||
|
||
### Act III — Resolution(约占全剧 25%)
|
||
- Falling Action(下落动作)
|
||
- Climax:最高潮时刻
|
||
- Denouement:解决与新平衡
|
||
- Thematic resolution(主题性结论与 Controlling Idea 对应)
|
||
|
||
## Relationship to Other Concepts
|
||
- [[HeroesJourney]]:三幕是组织骨架,Hero's Journey 是其内容填充
|
||
- [[Kishotenketsu]]:日本四幕结构,在第三/四幕之间无危机,直接延伸——跨文化对比框架
|
||
- [[Character-Arc]]:角色弧线必须在三幕中完成:Setup (want/lie) → Confrontation (testing the lie) → Resolution (confronting truth)
