旋律说唱（sing-rap）是个混合体，AI 经常两边都跑偏：要么写成完全的流行歌没有真正的 rap verse，要么 verse 还行但 hook 没旋律指引。要稳定出货，得在 Prompt 里把两半分开锁死：hook 写明旋律走向 + 短重复短语，verse 写明 bar 数和 Flow 类型，再强制整首歌出现一次情绪转折。下面给出 10 套可直接复制的模板。
这类歌词的结构是怎样的
一首现代 sing-rap 几乎都遵守这个骨架：
- Intro hook：2-4 bar，旋律性，短重复短语
- Verse 1：8-12 bar，half-time trap 或三连音 Flow
- Pre-hook：2-4 bar，旋律开始上扬
- Hook：4-8 bar，完整旋律，1 意象 + 1 动作
- Verse 2：8-12 bar，把情绪推进
- Hook：重复
- Bridge：half-time 切换，旋律为主，可选 spoken-word
- Final hook：升调，加一句只出现一次的句子
把这个骨架写进 Prompt，模型就不会两头跑偏。
一个好 Prompt 通常包含什么
- 主题 —— 不写”失恋”，要写”那晚你意识到她其实早就走了，只是身体还在”
- 结构 —— intro / verse / hook / bridge 每段 bar 数写明
- Hook 约束 —— 1 意象 + 1 动作，短重复短语，旋律走向写明（“上扬旋律，落在第四拍”）
- 禁止词 —— “心里碎了 / 我没救了 / 失去你之后 / 都是我的错”
- 押韵 —— Verse 多音节；Hook 简单句尾韵（唱出来要顺）
- 语气 —— 阴郁、内省、半唱半说、夜驾、club catharsis
- 每段长度 —— Verse 8-12 bar、Hook 4-8 bar、Bridge 4 bar

End the bridge with one short spoken-word line in his voice, not yours.容易踩的坑
- Hook 没旋律指引 —— 整首读起来像 rap 加弱副歌；要明写”rising melody, falls on the 4”或”low-register sung melody”
- Verse 只有 4-6 bar —— 听起来像 sung pre-chorus；每段 bar 数都要写明
- 没有情绪转折点 —— sing-rap 通常需要一个转折，指明位置（Verse 2 的 bar 9，或 Bridge）
- 没写禁止词 —— 8 bar 之内就跑出”心里碎了 / 失去你之后”
- Hook 和 Verse 押韵密度一样 —— Hook 要简单句尾韵（好唱），Verse 要多音节内韵
下一步怎么改得更好
- 先单独跑 Hook —— 读出来不好唱就先重生成，再写 Verse
- Verse 按 70-90 BPM 读一遍，音节卡顿就让模型每句砍 1-2 个音节
- Hook 里加一个具体小物（不写”爱”，而是”夹克里那张收据”）
- 每首歌强制加一句 spoken-word，旋律段落更有重量
- 同一 Prompt 跑男视角和女视角两遍，比较哪个版本套话更少
常见问答 (FAQ)
Q：为什么模型写出来像流行歌加几句 ad-lib，不像真正的 sing-rap？ A：每段 bar 数和 Flow 类型必须写明。“verse: half-time trap, multi-syllabic internal rhymes.” 不写的话模型默认用最熟的格式，也就是流行歌。
Q：怎么让 Hook 真的能唱，不是 rap 加节奏？ A：写明”rising melody, fall on the 4”或”low-register sung melody, mid-tempo”。指定旋律方向和音区，模型才会写出支撑歌唱的句式。
Q：sing-rap 一定要写失恋题材吗？ A：不用。这个格式对公路、家人未寄信、小成就回望、夜驾独处都成立。无论主题，Hook 永远是 1 意象 + 1 动作。
Q：怎么避开”心里碎了”那种默认情绪词？ A：明确写禁止词清单（“心里碎了 / 我没救了 / 失去你之后 / 都是我的错”）。模型默认用安全的情绪词汇，禁掉它才会去找具体画面。
Q：Bridge 是唱还是 rap？ A：最稳的做法是 Bridge half-time 切换、旋律为主，最后半句是 spoken-word。spoken-word 那一句锚住整首歌，回到 final hook 时冲击力会更大。
