  "prompt": "Genre: Smooth Jazz / Lounge / Contemporary R&B; BPM: 121; Key: A minor; Feel: Straight 16ths with a light swing, relaxed and syncopated pocket, driven by detailed hi-hat work; Instruments: Acoustic Piano (main harmony and melody, bright and clean tone), Fretless E.Bass (melodic counterpoint, smooth 'mwah' tone), Drum Kit (tight rhythmic foundation, crisp snare, detailed ride cymbal), Clean E.Guitar (atmospheric arpeggios, light chorus), Synth String Pad (sustained harmonic support); Lead: E.Guitar: Intro; Piano: A-section, B-section, Climax; Motif: A syncopated, descending melodic fragment in A minor, often resolving on the tonic, with a rhythm of eighth-eighth-quarter; Harmony: Lush, extended jazz harmony with maj7, 9, and 13 chords, smooth voice-leading and frequent ii-V-I cadences; Mood: Late-night drive through a quiet city, streetlights reflecting on wet pavement.; Highlight: The continuous melodic dialogue between the crisp grand piano and the fluid, singing fretless bass.",
  "cover_prompt": "A near-empty urban street at 2 a.m., slick pavement mirroring amber and violet streetlights in long, liquid streaks. The scene is hushed and luminous, shallow depth of field softening distant traffic signals into warm bokeh halos against deep indigo shadows. Cinematic photography, anamorphic lens flare, grain-textured noir palette.",
