cinematic orchestral waltz, airy and sweeping, piano lead with full symphonic support, delicate bell chimes as a recurring river-like motif, dynamic arc with swelling crescendos and quiet reflective moments, 3/4 time, moderate-to-fast waltz tempo, emotional but not heavy, no march, no choir, no low cello tones, spacious concert-hall sound, warm male vocal, clear voice, no rasp, sincere delivery, nostalgic and bittersweet atmosphere, love carried by the river and wind, stars reflecting in water, gentle longing with a sense of fading footsteps
