Cinematic ambient folk, slow tempo, intimate female vocal, warm and clear, with a pronounced echo and reverb. The voice should sound like it sings in a vast, stone-walled hall — soft reflections, a gentle delay that follows each line. Instruments: soft piano, distant cello, gentle strings. Atmosphere: sacred, spacious, timeless. Add a noticeable but delicate echo to the vocal, with reflections that fade slowly into silence.
