1. Aristotle's Six Elements Formula | 亚里士多德戏剧六要素公式
Aristotle’s analytical framework defines tragedy through six interconnected elements, often expressed as: Plot + Character + Thought + Diction + Song + Spectacle = Tragedy. Plot (mythos) is the “soul” of the drama, and all other elements are subordinate to the structured arrangement of incidents.
亚里士多德的分析框架通过六个相互关联的元素定义悲剧，常表示为：情节 + 性格 + 思想 + 言语 + 歌曲 + 景观 = 悲剧。情节（mythos）是戏剧的“灵魂”，其他所有元素都从属于事件的有机编排。
- Plot (mythos) – the arrangement of events; must have a beginning, middle, and end, with peripeteia (reversal) and anagnorisis (recognition). / 情节 – 事件的安排；必须有开始、中间和结尾，包含突转（peripeteia）和发现（anagnorisis）。
- Character (ethos) – the moral qualities revealed through choice, not mere description. / 性格 – 通过选择而非单纯描述展现的道德品质。
- Thought (dianoia) – the themes, arguments, and rhetorical logic of the play. / 思想 – 戏剧的主题、论证和修辞逻辑。
- Diction (lexis) – the language, metaphor, and verbal expression. / 言语 – 语言、隐喻和口头表达。
- Song (melos) – the musical, rhythmic and choral dimensions. / 歌曲 – 音乐、节奏及合唱的维度。
- Spectacle (opsis) – the visual elements, though the least artistic and related more to the craft of production. / 景观 – 视觉元素，尽管与艺术性关系最弱，更多与制作技艺相关。
2. Stanislavski’s System: The “Magic If” Theorem | 斯坦尼斯拉夫斯基体系：“假如”定理
The core of Stanislavski’s psychological realism can be summarised as: Real Emotion = Given Circumstances + “Magic If” + Concentration of Attention. The actor asks, “What would I do if I were in this situation?” to spark truthful, organic inner life.
斯坦尼斯拉夫斯基心理现实主义的核心可概括为：真实情感 = 规定情境 + “假如” + 注意力集中。演员通过问自己“假如我身处此境，我会怎么做？”来激发真实有机的内心生活。
- Given Circumstances – the facts of the play (time, place, relationships). / 规定情境 – 剧本中的事实（时间、地点、人物关系）。
- The “Magic If” – activates imagination, transforming the fictional into a credible experience. / “假如” – 激活想象，将虚构转化为可信的体验。
- Concentration of Attention – the actor focuses on the “Circles of Attention” to shut out distractions and listen truthfully. / 注意力集中 – 演员聚焦于“注意力圈”，排除干扰，真诚倾听。
- Emotion Memory – recalling personal experiences to feed a role, used sparingly to avoid hysteria. / 情绪记忆 – 回忆个人经历以滋养角色，谨慎使用以避免失控。
3. Brecht’s Verfremdungseffekt (Alienation Effect) Equation | 布莱希特间离效果方程式
Brecht’s epic theatre breaks the illusion of reality: Alienation = Showing that you are showing (Gestus + Historicisation + Narration) – Empathetic Identification. The aim is critical detachment, not emotional immersion.
布莱希特的史诗剧打破现实幻觉：间离 = 展示你是正在展示（姿态 + 历史化 + 叙述）– 移情认同。目的在于批判性抽离，而非情感沉浸。
- Gestus – a socially significant physical attitude that reveals power relations (e.g. the downtrodden worker’s walk). / 姿态 – 揭示权力关系且具有社会意义的身体态度（例如受压工人行走的方式）。
- Historicisation – treating events as “one-off”, contingent historical moments, not inevitable fate. / 历史化 – 将事件视为“仅此一次”的、偶然的历史瞬间，而非必然命运。
- Direct Address & Narration – actors step out of character, use placards, songs, and commentary. / 直接对白与叙述 – 演员跳出角色，使用标语牌、歌曲和评论。
- Episodic Structure – scenes are self-contained, juxtaposed like a montage to provoke thought. / 片断式结构 – 场景各自独立，如蒙太奇般并置，激发思考。
4. The Given Circumstances Formula | 规定情境公式
Beyond Stanislavski, Given Circumstances function as an analytical tool for any practitioner: Character Action = Given Circumstances × Objective ÷ Obstacle. Understanding the fictional “facts” unlocks consistent, motivated behaviour.
在斯坦尼斯拉夫斯基之外，规定情境还可作为任何实践者的分析工具：角色行动 = 规定情境 × 目的 ÷ 障碍。理解虚构的“事实”能解锁连贯且动机充分的行为。
| Component / 成分 | Definition / 定义 |
| Time / 时间 | Historical era, time of day, decade. / 历史时期、一天中的时刻、十年。 |
| Place / 地点 | Indoor/outdoor, country, social environment. / 室内或室外、国家、社会环境。 |
| Relationships / 关系 | Status, emotional bonds, power dynamics. / 地位、情感纽带、权力动态。 |
| Pre-history / 前史 | Events immediately preceding the scene. / 紧接场景之前的事件。 |
5. Laban’s Movement Analysis: Effort Actions Theorem | 拉班动作分析：力效定理
Laban’s taxonomy describes all human movement through combinations of four motion factors: Effort = Weight × Space × Time × Flow. By varying each, performers create distinct movement qualities—fundamental for physical theatre and characterisation.
拉班的分类通过四个运动因子的组合来描述所有人体动作：力效 = 重力 × 空间 × 时间 × 流畅度。表演者通过改变每个因子，创造出不同的动作质感——这对物质剧场和角色塑造至关重要。
- Weight (Light ↔ Strong) – delicate touch vs. forceful punch. / 重力（轻↔重） – 轻柔的触碰与有力的击打。
- Space (Direct ↔ Indirect) – focused, channelled movement vs. expansive, sweeping gestures. / 空间（直接↔间接） – 专注、定向的运动与延伸、扫掠的姿势。
- Time (Sudden ↔ Sustained) – quick, staccato action vs. slow, continuous motion. / 时间（突发↔持续） – 快速、顿挫的动作与缓慢、连续的运动。
- Flow (Bound ↔ Free) – controlled, stoppable movement vs. fluid, ongoing flow. / 流畅度（拘束↔自由） – 可控、可停止的运动与流畅、持续不断的流动。
The eight basic Effort Actions (Press, Wring, Slash, Punch, Float, Glide, Dab, Flick) emerge from pairing three of these factors. / 八个基本力效动作（压、拧、砍、击、浮、滑、点、弹）由其中三个因子的组合产生。
6. The Well-Made Play Structure Formula | 佳构剧结构公式
Perfected by Scribe and Ibsen, the well-made play relies on a causal chain: Climax = Exposition + Rising Action (Secrets/Reversals) + Obligatory Scene + Resolution. Tense logic and withheld information keep the audience engaged.
由斯克里布和易卜生完善的佳构剧依赖因果链条：高潮 = 展示 + 上升行动（秘密/逆转） + 必需场面 + 解开。紧张的逻辑和信息的扣留使观众保持投入。
- Exposition – background delivered through dialogue or a confidant. / 展示 – 通过对话或知己角色传递背景。
- Rising Action & Secrets – a letter, missing document, or hidden identity creates suspense. / 上升行动与秘密 – 信件、丢失文件或隐藏身份制造悬念。
- Obligatory Scene (Scène à faire) – the moment of confrontation the audience anticipates. / 必需场面 – 观众所期待的正面交锋时刻。
- Reversal/Recognition – a twist that re-frames the entire situation. / 逆转/发现 – 重塑全局的转折。
- Denouement – logical unravelling where all loose ends are tied. / 解开 – 逻辑梳理，所有线索收束。
7. Artaud’s Theatre of Cruelty: Sensory Assault Theorem | 阿尔托残酷戏剧：感官冲击定理
Artaud replaces psychological narrative with a total sensory bombardment: Theatrical Effect = ∫ (Sound + Light + Gesture + Space + Breath) – Verbal Text. Language is dethroned; the mise-en-scène becomes a concrete, physical language.
阿尔托以全面感官轰炸替代心理叙事：剧场效应 = ∫ (声音 + 光线 + 手势 + 空间 + 呼吸) – 语言文字。语言被罢黜；舞台调度成为一种具体的物质语言。
- Excessive Volume & Frequency – piercing cries, amplified whispers, dissonant music. / 极端音量与频率 – 刺耳哭喊、放大低语、不和谐音乐。
- Pulsating Light & Darkness – sudden blackouts, strobes, colour washes to strike the nervous system. / 脉动光线与黑暗 – 突然黑场、频闪、色彩铺洒以冲击神经系统。
- Hieroglyphic Gesture – symbolic, non-psychological movement replacing mimetic acting. / 象形文字式手势 – 象征性的、非心理化的动作，取代模仿式表演。
- Audience Centrality – spectators placed in the centre, engulfed by action from all sides. / 观众中心化 – 观众置于中央，被四面八方的行动吞没。
8. Lighting Design: 45-Degree Key Light Rule | 灯光设计：主光45度法则
A foundational theorem for modelling three-dimensionality on stage states: pth = Key Light at 45° Horizontal + 45° Vertical from subject + Fill Light at 30° opposite. This creates natural shadows that define facial contours without flattening the figure.
舞台上塑造三维立体感的基础定理为：深度 = 主光从对象水平45° + 垂直45°位置照射 + 补光从对面30°补充。这能形成自然的阴影，勾勒面部轮廓而不使人物扁平化。
- Key Light – primary source, sets mood and direction. / 主光 – 主要光源，设定情绪和方向。
- Fill Light – softens shadows; ratio to key determines contrast (high key = bright; low key = moody). / 补光 – 柔化阴影；与主光的光比决定对比度（高调明亮；低调阴沉）。
- Backlight – separates actor from background, creating a “halo” rim. / 背光 – 将演员与背景分离，产生“光晕”轮廓。
- Gels & Temperature – cool (CTB) vs warm (CTO) colours for time of day or emotional temperature. / 色纸与色温 – 冷色（CTB）与暖色（CTO）表现时间或情感温度。
- Conflict – internal (psychological) or external (character vs. character / society). / 冲突 – 内在（心理）或外在（角色对角色/社会）。
- Stakes – what will be gained or lost; must escalate. / 赌注 – 将会得到或失去什么；必须逐步升级。
- Pacing – sentence length, pauses, physical tempo. Rapid fire = panic; drawn out = dread. / 节奏 – 句子长度、停顿、身体速度。连珠炮式 = 恐慌；拖长 = 恐惧。
- Subtext – the unspoken meaning beneath the words; when it surfaces, tension releases or spikes. / 潜台词 – 言语之下的未言之意；当它浮出水面时，张力释放或激增。
- Stimulus Sources – photograph, poem, artifact, news event, piece of music. / 刺激来源 – 照片、诗歌、文物、新闻事件、一段音乐。
- Improvisation Techniques – hot seating, freeze frame, thought tracking, moment work. / 即兴技巧 – 坐针毡、定格、思路追踪、瞬间工作。
- Audience Integration – testing fragments in front of peers early; their response reshapes the work. / 观众整合 – 早期在同伴面前测试片段；他们的反应重塑作品。
- Documentation – keep logs, sketches, sound files to map the genealogy of ideas. / 记录 – 保存日志、草图、声音文件，以追踪想法的谱系。
- Icon – resembles what it represents (e.g. a throne = power). / 像似符 – 与所代表物相似（如王座 = 权力）。
- Index – points to a cause or effect (smoke = fire; a limp = injury). / 指示符 – 指向原因或结果（烟 = 火；跛脚 = 受伤）。
- Symbol – arbitrary, culturally agreed (white dress = purity in Western context). / 象征符 – 任意、文化约定（白色礼服在西方语境中 = 纯洁）。
- Denotation & Connotation – denotation is the literal thing; connotation is the associative meaning (red light denotates a colour; connotes danger or passion). / 外延与内涵 – 外延是字面事物；内涵是联想意义（红光外延为一种颜色，内涵为危险或激情）。
9. Sound Design: The Audio Perspective Theorem | 声音设计：听觉透视定理
Sound creates spatial and psychological depth through a simple equation: Audience Immersion = Diegetic Sound × Miking Technique + Reverberation & Panning. Perspective can shift from omniscient narrator to inner monologue in an instant.
声音通过简单方程式创造空间与心理深度：观众沉浸 = 剧情内声音 × 拾音技巧 + 混响与声像定位。透视可在瞬间从全知叙述者转变为内心独白。
| Term / 术语 | Formula / 公式 |
| Diegetic / 剧情内声音 | Source is visible on stage or implied in the world (radio, footsteps). / 声源可见或在戏剧世界中暗示（收音机、脚步声）。 |
| Non-Diegetic / 剧情外声音 | Only the audience hears it (underscore, voice-over). / 只有观众听到（配乐、画外音）。 |
| Surround Panning / 环绕声像 | Locates sound in a 360° field around the auditorium. / 将声音定位于观众席周围360°场域。 |
| Reverb Time (RT60) / 混响时间 | Short reverb = intimacy; long reverb = vast, alienating space. / 短混响 = 亲密；长混响 = 广阔、疏离的空间。 |
10. Tension Curve Formula | 张力曲线公式
Tension in a scene or whole play can be modelled as a function of Conflict + Stakes + Pacing + Subtext. The curve typically resembles a rising sawtooth: a series of crises each higher than the last, separated by brief respiration.
场景或整部戏中的张力可建模为 冲突 + 赌注 + 节奏 + 潜台词 的函数。张力曲线通常呈上升锯齿状：一系列危机，每次都比前一次更高，中间由短暂的呼吸分隔。
11. Devising: The Stimulus-Response Cycle | 编创：刺激-反应循环
Devising generates material through an iterative algorithm: ₊₁ = (Stimulus + Research) → Improvisation → Selection & Refinement → Feedback → Materialₙ. Each cycle deepens the ensemble’s ownership and sharpens the political/aesthetic focus.
编创通过迭代算法生成材料：材料ₙ₊₁ = (刺激 + 研究) → 即兴 → 选择与提炼 → 反馈 → 材料ₙ。每个循环加深集体的归属感，并打磨政治/美学焦点。
12. Semiotics of Theatre: Sign = Signifier + Signified | 剧场符号学：符号 = 能指 + 所指
Every stage element is a sign. The fundamental Saussurean–Peircean theorem applied to theatre states: Theatrical Sign = Signifier (physical form) + Signified (mental concept). The relationship can be iconic, indexical, or symbolic, and signs multiply through polyphony: a single costume simultaneously communicates period, class, and psychology.
舞台上每个元素都是符号。将索绪尔–皮尔斯的根本定理应用于剧场得出：剧场符号 = 能指（物质形式） + 所指（心理概念）。这种关系可以是像似、指示或象征的，而符号通过复调性成倍增长：一件戏服同时传达时代、阶级和心理。
Directors manipulate sign systems (set, props, lighting, sound, gestural) to build a “universe of meaning” that audiences decode in real time. / 导演操控符号系统（布景、道具、灯光、声音、手势）构建一个“意义宇宙”，观众在实时中解码。
