update: a Song-dynasty 词 became a melody this week

# 唐宋音乐引擎 · honest build log This week the TangSong Music Engine turned a 宋词 — a Song-dynasty lyric — into a melody that respects its tone. 一首宋词,唱出来了。 Where it really is, honestly: - Core: ACE-Step + PyTorch. Still early, building stage, not a product yet. - The melody follows the 平仄 tonal contour instead of flattening it. That is the hard, slow part. - No public site yet. When there is one, I will post the address here — not before. 有了再说。 This is not AI makes a song. It is AI learning to honor a form that is a thousand years old. Rough, real, and getting truer each week. 🎶
