  "prompt": "Genre: Mandopop / R&B Ballad; BPM: 66; Key: E major; Rhythm: Slow 4/4 time with a simple, soft backbeat. Minimal drums (side-stick snare, gentle kick) and a supportive, root-note focused bassline create a sparse, emotional foundation.; Instruments: Fingerpicked acoustic guitar (arpeggios), warm grand piano (chords/melodies), clean electric bass (low-end support), minimal drum kit (soft touch), lush orchestral string section (swelling pads for emotional lift).; Vocals: Male tenor, intimate and breathy with a slightly raspy timbre. Mix of chest voice and gentle falsetto for emotional emphasis. Light reverb and natural compression.; Mood: Melancholic, introspective, heartfelt, vulnerable.; Production: Polished, spacious mix. Vocals are upfront and centered. Wide stereo field, especially with strings. Hall reverb creates an emotional, expansive soundscape.; Highlight: the intimate and breathy vocal delivery, transitioning to a gentle falsetto.",
