{"status": "success", "json_a": {"prompt": "Genre: Cinematic Neoclassical / Ambient Piano; BPM: 99; Key: A Major; Rhythm: Flowing piano arpeggios in a loose 4/4, expressive rubato feel, with chordal pushes and suspensions creating a breath-like pulse; Instruments: Grand piano, felt hammers, resonant wood body, sustained pedal hum, vast room reverb; Ocean waves SFX, constant gentle surf; Vocals: Instrumental; Mood: Standing on a cliff overlooking a grey ocean at dawn, feeling the cold wind but also the first warmth of the sun on your face; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Vast stereo field, natural reverb tails, SFX blended seamlessly, minimal compression to preserve dynamics.; Structure: Intro - Verse - Chorus - Verse - Interlude - Chorus - Outro; Language: Instrumental; Highlight: The single, rapid upward arpeggio at 0:22, a flash of virtuosity that breaks the calm, like a sudden gust of wind across the water.", "lyrics": "[intro]\n(Mix: Wide stereo image, ocean SFX panned wide and deep.
