对唱歌词最容易写废的方式只有一种：A 和 B 说着差不多的话，只是换了几个词。双视角对唱真正想做的，是让两个声音在同一个场景里看到不同的东西，最后在 Bridge 里正面相撞。AI 默认会写成「我也想你 / 我也想你」这种糊在一起的东西，除非你强行拉开两个声音的距离。下面 10 个可直接复制的双视角 Prompt 模板，把两个角色的意象集、禁用重叠、Bridge 相撞结构都锁死。
双视角对唱真正在用的结构
工业流水线上的对唱几乎都是这个骨架：
- Verse 1A：A 视角的场景与内心
- Verse 1B：B 视角的同一时刻，换一套意象
- Chorus（合唱）：两个人都在想但谁也不说出口的那句
- Verse 2A：A 推进剧情
- Verse 2B：B 同步推进
- Chorus（合唱）
- Bridge（call-and-response）：A 一句 / B 一句 / A 一句 / B 一句，正面对话
- Final Chorus（合唱 + 一句只出现一次的新词）
把这个结构直接写进 Prompt，AI 就不会把两个声音糊成一个声音。
一个高质量双视角 Prompt 应该包含什么
- 两个角色定位 —— A：38 岁妻子，疲惫；B：41 岁丈夫，防御
- 两套意象集 —— A：厨房 / 咖啡 / 日历；B：车库 / 钥匙 / 仪表盘
- 禁止重叠 —— 列出两人不能互相借用的词
- 副歌规则 —— “两人都在想但谁也不说出口的那一句”
- Bridge 格式 —— call-and-response，4 句轮流
- 押韵 —— 两个声音同韵脚，合唱才不会打架
- 长度 —— 每段 verse 4 句，副歌 4 句，Bridge 4 句

Mood: layered, unresolved.容易踩的坑
- 两个声音 / 一个内心 —— A 和 B 听起来像同一个人
- Bridge 还在唱副歌 —— Bridge 必须切到 call-and-response
- 两套意象重叠 —— 分别指定意象集并禁止互借
- 副歌写得太长 —— 副歌只放”两人共享的一句”
- Final Chorus 完全重复 —— 必须加一句只出现一次的新词
下一步怎么改得更好
- 给 A 和 B 各一个反复出现的名词（A = “the door”，B = “the window”），让它们在 Bridge 相撞
- 全篇禁用 “we”，直到 Final Chorus 才允许出现
- 一个声音用过去时，一个用现在时，到 Bridge 合一
- 先写完 A 的所有 verse，再让 B 作为对位写，不要并行写
- 单独读 A 或 B 的部分 —— 任何一个能独立成歌，双视角就成立了
常见问题（FAQ）
Q：AI 总是把 A 和 B 写成同一个人？ A：分配两套不重叠的意象集，再加一行 forbidden overlap。意象一分开，模型就被迫进两个身体。
Q：副歌听起来像一首独唱？ A：副歌是唯一两个声音真正同步的位置。把它写成”两人都在想但谁也不会单独说的那一句”。
Q：Bridge 一直在重复副歌？ A：把 Bridge 锁成 call-and-response，4 句轮流。结构变了，副歌循环就被打断。
Q：每段 verse 多长合适？ A：每个声音 4 句。再长，第二个声音等太久，整首歌的节奏会塌。
Q：可以加第三个声音吗？ A：可以，但要写成只在 Bridge 进入的对位，否则双视角的张力会塌掉。
