  "lyrics": "[纯音乐]",
  "prompt": "Genre: Gypsy Jazz / Klezmer Fusion; BPM: 102; Key: G minor; Feel: Intro is expressive rubato; main sections are a driving, fast-paced 'two-feel' (alla breve) with a tight Gypsy Jazz swing pocket and virtuosic, heavily syncopated lead lines.; Instruments: Clarinet (lead melody and improvisation, warm woody tone with expressive breathiness and wide dynamic range), Acoustic Steel-string Guitar (rhythmic \"la pompe\" chording, improvised soloing, and harmonic support; bright and percussive tone).; Lead: Clarinet: Intro+A+B sections; Ac.Guitar: first half of Solo-section; Clarinet: second half of Solo-section + final B-section + Outro.; Motif: A mournful, descending melodic cell starting on the 5th (D), moving through the minor 3rd (Bb), often embellished with chromatic passing tones and fast scalar runs.; Highlight: The stark dynamic and tempo shift from a mournful, rubato clarinet intro to a frenetic, high-speed ensemble improvisation.",
  "cover_prompt": "A dimly lit cobblestone alley at dusk, smoke curling from iron lanterns casting amber pools of light onto rain-slicked stones, the air heavy with an almost tangible melancholy. Worn wooden shutters and trailing ivy frame the narrow passage, the scene caught in that electric tension between stillness and frenzy. Rich chiaroscuro tones of deep indigo, burnt sienna, and tarnished gold, rendered in a loose, expressive oil painting style with visible impasto brushwork.",
