WEIYANG SOUND · 未央声场
七夕多声线实验
同一七夕母题进入深厚女声、清亮女声与南亚电影男声，让 cover、改写与姐妹歌之间的边界真正可听。
SHARED MOTIF · DISTINCT WORKS
专辑命题
同一七夕母题进入深厚女声、清亮女声与南亚电影男声，让 cover、改写与姐妹歌之间的边界真正可听。
证据边界
四件公开作品并不等于同一首歌的四个无差别文件；共享歌词、父节点与独立新词继续分层登记。
Qixi Multi-Voice Lab
One Qixi motif enters deep female, clear female and South Asian cinematic male voices, making the boundary between cover, rewriting and sister song audible.
Evidence boundary
Four public works are not four interchangeable files of one song. Shared lyric, parent lineage and independently written text remain separate evidence layers.
