Folk ballad with slow 6/8 sway, sparse fingerpicked guqin-like plucks and bowed strings; verse stays intimate with room tone and bare percussion, pre-chorus lifts with trembling harmony and a low drone, chorus opens into warm unison and a short chantable refrain. Lead vocal is close-mic and breathy in verses, doubled on key lines, with soft delay throws on the hook and a few wordless backing vowels. Frosty wind swells, reversed string tails, and a quiet frame drum lift transitions. Wide, cinematic but earthy mix.
