1. Aristotle’s Six Elements of Drama | 亚里士多德戏剧六要素
Plot (mythos): The arrangement of incidents; the ‘soul’ of tragedy. A unified action with a beginning, middle and end.
情节：事件的安排，是悲剧的“灵魂”。一个统一行动，有开头、中间和结尾。
Character (ethos): The moral qualities and motivations of the agents. Character supports plot; it is revealed through choices.
角色：行动者的道德品质与动机。角色为情节服务，通过选择揭示。
Thought (dianoia): The themes, arguments and ideas of the play – what the characters say and prove.
思想：剧作的主题、论点和观念——角色所说与所证明的。
Diction (lexis): The expression of meaning through words; the quality of speech, including metaphor and rhythm.
措辞：通过词语表达意义；言语的质量，包括隐喻和节奏。
Music (melos): All auditory elements – rhythm, melody, chorus singing. Enhances emotional response.
音乐：所有听觉元素——节奏、旋律、合唱。增强情感反应。
Spectacle (opsis): The visual aspects – set, costume, lighting, blocking. The least artistic but emotionally impactful.
景象：视觉方面——布景、服装、灯光、舞台调度。艺术性最低但情感冲击性强。
2. Stanislavski’s System: Core Equations | 斯坦尼斯拉夫斯基体系核心原理
Super-objective + Through-line of Action: The character’s overarching goal drives every scene. Every unit of action has a micro-objective that feeds the spine.
超任务 + 贯串动作：角色的总体目标驱动每一场戏。每个行动单元都有一个微小目标，共同构成主线。
Given Circumstances: The facts of the world – time, place, relationships, social background. The actor asks: ‘What would I do if I were in these circumstances?’
特定情境：舞台世界的事实——时间、地点、人际关系、社会背景。演员自问：“如果我身处此境，我会怎么做？”
Emotion Memory: Recalling personal past experiences to trigger genuine feelings analogous to the character’s. Used sparingly to avoid hysteria.
情绪记忆：回忆个人过往经历，以触发与角色相似的真诚情感。谨慎使用以免情绪失控。
Magic If: The imaginative leap – ‘What if this situation were real?’ Transforms the fictional into truthful action.
魔法假如：想象力的跳跃——“假如这情境是真实的？”将虚构转化为真实的行动。
Circles of Attention: A technique to focus energy – from the self, to the immediate partner, to the whole stage. Eliminates audience-induced tension.
注意力圈：集中能量的技巧——从自我，到对手，到整个舞台。消除观众造成的紧张。
3. Brecht’s Epic Theatre & The ‘A-Effect’ | 布莱希特史诗剧与“间离效果”
Verfremdungseffekt (Alienation Effect): The formula V = R + S – Recognition disrupted by Strangeness. The familiar is made unfamiliar to provoke critical thought, not empathy.
间离效果：公式 V = R + S——认知被陌生化打断。熟悉的事物变得陌生，以激发批判性思考，而非共情。
Gestus: A physical stance, gesture or tableau that encapsulates a social relationship or attitude. It shows, not becomes – revealing the social gesture of a moment.
姿态：一种能概括社会关系或态度的身体姿势、手势或定格画面。展示而非变成——揭示某一时刻的社会性姿态。
Historicisation: Events are presented as products of a specific historical moment, not human nature. Reminds the audience that things can change.
历史化：事件被呈现为特定历史时刻的产物，而非人性使然。提醒观众：世事可变。
Epic Structure: Episodic scenes, often separated by songs, narration or captions. Breaks illusionistic flow, encouraging analytical distance.
史诗结构：分场的、片段化的场景，常被歌曲、叙述或字幕打断。瓦解幻觉流，鼓励分析距离。
4. Grotowski’s Poor Theatre: Actor-Spectator Formula | 格洛托夫斯基贫困戏剧：演员-观众公式
Via Negativa: The actor strips away rather than adds – eliminating blocks, masks and cliches to reveal pure impulse. Technique is a process of subtraction.
否定法：演员剥除而非添加——消除障碍、面具和程式化表演，展现纯净的冲动。技艺是一种减法过程。
Actor–Spectator Relationship: Theatre is what happens between the actor and the spectator. Everything else – lights, costume, set – can be discarded (poor theatre).
演员-观众关系：戏剧发生在演员与观众之间。其余一切——灯光、服装、布景——皆可舍弃（贫困戏剧）。
Holy Actor: The performer undergoes a total act of self-penetration, offering their deepest psyche – a secular holiness that transforms the audience.
圣洁演员：表演者经历彻底的自我穿透，奉上最深层的心灵——一种世俗的神圣性，以转化观众。
5. Peter Brook’s Empty Space & Immediate Theatre | 彼得·布鲁克的空的空间与即时戏剧
The Empty Space Formula: ‘I can take any empty space and call it a bare stage. A man walks across this empty space whilst someone else is watching him, and this is all that is needed for an act of theatre to be engaged.’
空的空间公式：“我可以选取任何一个空的空间，称之为光秃的舞台。一个人走过这个空的空间，而另一个人在观看——这就是构成戏剧行为所需要的全部。”
Deadly Theatre: Repetitious, predictable, museum-like production that lacks connection to the present. Avoid it by questioning every convention.
致命的戏剧：重复、可预见、像博物馆一样的制作，与现时脱节。通过质疑一切惯例来避免它。
Immediate Theatre: Live performance that creates a unique, irreplaceable connection each night – an event in the here and now.
即时戏剧：每晚都创造独特、不可复制的联结的现场表演——一个此时此地的事件。
6. The Three-Act Structure Theorem | 三幕结构定理
Act I: Setup – Introduces the world, protagonist and their desire. The inciting incident at the end destroys equilibrium and launches the dramatic question.
第一幕：建置——介绍世界、主角及其欲望。幕尾的激励事件打破平衡，引发戏剧问题。
Act II: Confrontation – The longest act. Rising obstacles, complications and a midpoint reversal. Ends with a crisis or ‘dark night of the soul’ leading to climax.
第二幕：对抗——最长的一幕。上升的障碍、复杂化和中点逆转。以危机或“灵魂黑夜”结束，引向高潮。
Act III: Resolution – Climax answers the dramatic question; denouement shows the new equilibrium. Catharsis for tragedy, celebration for comedy.
第三幕：解决——高潮回答戏剧问题；结局展示新的平衡。悲剧走向净化，喜剧走向庆祝。
7. Freytag’s Pyramid: Dramatic Tension Formula | 弗莱塔格金字塔：戏剧张力公式
Exposition → Rising Action → Climax → Falling Action → Denouement. Tension (T) builds with each reversal and recognition, peaking at the climax.
展示 → 上升行动 → 高潮 → 下降行动 → 结局。张力（T）随每一次突转和发现而增加，在高潮达到顶点。
Catastrophe: In tragedy, the final resolution brings suffering and emotional cleansing (catharsis). In modern plays, the pyramid may be inverted or fragmented.
灾变：在悲剧中，最终解答带来苦难和情感净化。在现代剧作中，金字塔可能被颠倒或打碎。
8. Stage Composition: Spatial Dynamics ‘Formula’ | 舞台构图：空间力学“公式”
The Nine-Zone Grid: Divide the stage into upstage/downstage and left/centre/right. Downstage centre (DC) carries most power; upstage left (UL) least focus. Use diagonals and triangles for dynamic tension.
九宫格：将舞台分为台前/台后及左/中/右。正中前区力量最强；后院左区焦点最弱。用对角线和三角形创造动态张力。
Levels & Proximity: Height = status or psychological intensity. Close proximity = intimacy or confrontation; distance = isolation or alienation. Apply proxemics mathematically.
高度与距离：高度 = 地位或心理强度。近距离 = 亲密或冲突；远距离 = 孤立或疏离。像数学般精确运用空间关系学。
Strong stage positions: The character facing front, body open, centre stage, elevated – holds the highest focus value. The stage picture should read like a painting.
强势舞台位置：面向正前、身体打开、位于舞台中心、高处——拥有最高焦点值。舞台画面应如绘画般可读。
9. Character Arc Equation | 角色弧线方程
Character Change (ΔC) = Obstacle × Pressure + Revelation – Fear. The protagonist’s transformation follows the action; a static character serves as a foil.
角色变化（ΔC） = 障碍 × 压力 + 揭示 − 恐惧。主角的转变随行动展开；静态角色作陪衬。
Subtext: The unspoken thoughts beneath the lines. Depth score = (Text + Action + Pause) / Spoken words. What is not said often carries the truest meaning.
潜台词：台词之下的未说之言。深度值 =（文本 + 动作 + 停顿）÷ 说出的话。未说出的往往承载最真实的含义。
Status Transactions: Every line shifts relative status (High/Low). A play is a series of status battles mapped on a graph of power.
地位交易：每句台词都会改变相对地位（高/低）。一部戏就是一场描绘在权力图表上的地位争夺战。
10. Lighting Design Formulae | 灯光设计公式
McCandless’ Rule: Each acting area illuminated by two fixtures at 45° above and 90° apart. Warm from one side, cool from the other – sculpts natural dimensionality.
麦坎德利斯法则：每个演区由两个灯位照明，灯位上方45°，水平间隔90°。一侧暖光，一侧冷光——塑造自然的立体感。
Key : Fill Ratio: Key light provides primary illumination; fill light reduces shadows. Typical ratio 2:1 for drama, 1:1 for comedy. Low key = high tension.
主光 : 辅光比：主光提供主要照明；辅光减弱阴影。剧情片典型比例2:1，喜剧1:1。低调光 = 高紧张。
Colour Psychology: Red = danger/passion, blue = cold/tranquillity, green = envy/sickness. Use complementary colours (e.g. cyan + amber) for shadow magic.
色彩心理学：红 = 危险/激情，蓝 = 冰冷/宁静，绿 = 嫉妒/病态。使用补色（如青 + 琥珀）创造阴影魔术。
11. Sound Design: Acoustic Equations | 音效设计：声学方程
Diegetic vs Non-diegetic: Sound originating from the world of the play (footsteps, radio) vs. score added for the audience only. The boundary can be blurred for effect.
剧情内与剧情外：源于剧中世界的声音（脚步声、收音机）与仅为观众添加的配乐。可有目的地模糊边界。
Volume Arc: Build volume (dB) to increase tension; sudden silence (negative dB spike) shock. Use sound bridges to link scenes smoothly.
音量弧线：建立音量（分贝）以增强紧张；突然的静默（负分贝峰值）制造震惊。使用声音桥接平滑连接场景。
Reverb Time (RT60): The time for sound to decay by 60 dB. Long reverb = vast, eerie space (church); short = intimate, dry (small room). Apply to set atmosphere.
混响时间（RT60）：声音衰减60分贝所需的时间。长混响 = 宏大、诡秘空间（教堂）；短混响 = 亲密、干燥（小房间）。用于营造氛围。
12. Devising Formula: From Stimulus to Performance | 创作公式：从刺激到表演
Fricative DNA: Start with stimulus (image, poem, object). Use Frantic Assembly’s building blocks: physical lifts, chair duets, round-by-through methodology.
Frantic DNA：从刺激物开始（图像、诗歌、物体）。使用Frantic Assembly的构建块：肢体托举、椅子双人舞、环绕-经过-穿越方法。
D.I.C.E Formula: Discover → Improvise → Craft → Edit. Generate material freely, then shape with precise dramaturgy.
D.I.C.E 公式：发现 → 即兴 → 创作 → 编辑。自由生成素材，然后用精确的戏剧构作加以塑形。
Actor’s Notebook Log: Record ‘What worked? Why? What is the next question?’ after each exploration. Every devising session should generate a new proposition.
演员笔记日志：每次探索后记录“什么有效？为什么？下一个问题是什么？”每次创作课都应产生一个新的提议。
