30秒纸屋制作短片：配乐需求单（自拟示例，未生成/试听音轨）

用途：30秒纸屋制作短片的背景配乐，保留折纸原声的位置。
整体：温暖、轻巧、少量推进感；毡音钢琴、轻拨弦、弱低音和克制的沙锤。目标96 BPM、4/4拍。
交付：包含尾音的30秒完整器乐段，不做无缝循环；不要歌词、人声、哼唱或人声采样。

| 时间 | 画面 | 音乐安排 |
| --- | --- | --- |
| 0–5秒 | 纸张和工具铺在桌上 | 稀疏钢琴或轻拨弦，不进鼓。 |
| 5–15秒 | 折叠、组装纸屋的快切 | 加入轻沙锤和低音，保持同一小动机。 |
| 15–25秒 | 纸屋成形，转动展示细节 | 和声稍丰满，旋律留白，不突然换风格。 |
| 25–30秒 | 成品定格和片尾文字 | 撤去打击乐，约27.5秒落最后和弦，尾音在30秒前收尽。 |

英文自然语言提示词：
Instrumental background music for a 30-second paper-house craft film. Target 96 BPM in 4/4, warm and light, with felt piano, soft plucked strings, muted bass and a restrained shaker. Keep the arrangement sparse so paper-folding sounds remain audible.
0–5s: a sparse piano or plucked introduction, no drums.
5–15s: add quiet shaker and bass under the assembly shots; keep one simple motif.
15–25s: slightly fuller harmony for the finished house, without a sudden style change.
25–30s: remove percussion and resolve, aiming for the final chord around 27.5s; let the full reverb tail finish by 30s.
One complete cue, not a seamless loop. No vocals, lyrics, humming, vocal samples or dramatic trailer rises.

使用说明：时间、BPM及收尾均为目标，非模型保证。按工具实际选项设置器乐/时长/节奏。生成后与画面试听，核对时段、人声、原声空间和尾音；不要把本需求单说成已完成的音轨。
