  "prompt": "Genre: Acoustic Pop-R&B Ballad; BPM: 115; Key: Bb Major; Rhythm: Gentle 4/4 groove driven by clean, arpeggiated acoustic guitar, supported by a subtle, laid-back programmed drum loop and soft snaps; Instruments: Closely-mic'd acoustic, shimmering reverb elec gtr, smooth synth sub-bass, soft programmed drums, warm synth pads; Vocals: Male, breathy intimate verses, soaring falsetto, gentle R&B melismas, lush background vocal stacks; Mood: The quiet, warm light of a nursery at 3 AM, holding a sleeping newborn and feeling the weight of a new world in your arms; Highlight: The moment at 0:55 where the sub-bass and a gentle kick enter for the first time, lifting the sparse arrangement just as the lead vocal shifts into a more earnest, melodic delivery on the downbeat, grounding the emotional memory.",

  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix. Wide stereo field. Clean, prominent acoustic guitar with audible string resonance. Warm sub-bass foundation. Silky smooth high-end.

Gentle onset.)\n(Inst: Acoustic guitar remains the primary focus. Subtle atmospheric pad enters.)\n(Chords: Ebmaj7 - Gm - F - Bb)\n你收进行李箱的\n是那件洗旧的毛衣\n我站在门框边没说话\n手里还捏着你的钥匙\n\n[chorus]\n(Hook-DNA: Rhythmic motif on \"I re-mem-ber the mo-ment\" (syncopated 8th-8th-quarter), anchoring on the 5th (F) over the tonic chord, repeats with slight melodic variation.)\n(Melody-Contour: Ascending arch shape, starts on the 3rd, leaps up a 4th to the 6th, resolves down.)\n(Melody-Rhythm: Phrases start consistently on beat 1, syncopated middle section, rests on beat 4 for breath.)\n(Melody-Harmonic-Tension: Holds the 6th (G) over the subdominant (Ebmaj7) chord, creating a gentle, sweet tension before resolving downwards as the harmony changes.)\n(Vocal-Perf: Shift to a fuller, more open tone. Falsetto used on higher notes.)\n(Inst: Gentle kick and clap enter, driving rhythm. Lush vocal stacks enter for harmony.)\n(Mix: Wider stereo image, more layers, parallel compression on vocals for presence.)\n(Chords: Eb - Bb/D - Cm7 - Fsus4 - F | Ebmaj7 - Gm - F - Bb - Gm - F)\n我想说\n留下来\n冬天还没过\n窗台的花\n刚发芽\n你别走\n我还记得那个黄昏\n你窝在沙发里睡着\n呼吸轻得像羽毛落地\n我不敢动\n怕把你惊醒\n也怕这一刻溜走\n\n[interlude]\n(Vocal-Perf: Layered falsetto vocals singing a simple, repetitive \"Yeah yeah\" melody, functioning as a melodic instrument.)\n(Inst: Rhythm section continues, guitars create a spacious bed.)\n(Chords: Ebmaj7 - Gm - F - Bb)\n留一点\n嗯嗯嗯嗯\n留一点给我\n嗯嗯嗯嗯\n\n[verse]\n(Vocal-Perf: Returns to intimate, story-telling delivery.)\n(Inst: Arrangement pulls back to acoustic guitar and pads.)\n(Chords: Ebmaj7 - Gm - F - Bb)\n饭桌上的那个杯子\n你走后我没再动过\n灰尘落在杯沿上\n像某种我说不出口的执着\n\n[chorus]\n(Hook-DNA: Rhythmic motif on \"I re-mem-ber the mo-ment\" (syncopated 8th-8th-quarter), anchoring on the 5th (F) over the tonic chord, repeats with slight melodic variation.)\n(Melody-Contour: Ascending arch shape, starts on the 3rd, leaps up a 4th to the 6th, resolves down.)\n(Melody-Rhythm: Phrases start consistently on beat 1, syncopated middle section, rests on beat 4 for breath.)\n(Melody-Harmonic-Tension: Holds the 6th (G) over the subdominant (Ebmaj7) chord, creating a gentle, sweet tension before resolving downwards as the harmony changes.)\n(Vocal-Perf: More emotional intensity than the first chorus. Ad-libs added in the background.)\n(Inst: Full arrangement, vocal stacks are more prominent.)\n(Mix: Dynamic peak of the song.)\n(Chords: Eb - Bb/D - Cm7 - Fsus4 - F | Ebmaj7 - Gm - F - Bb - Gm - F)\n我想说\n等一等\n路还很长\n那件旧毛衣\n缩水了\n还在箱底躺\n我还记得那个黄昏\n你窝在沙发里睡着\n呼吸轻得像羽毛落地\n我不敢动\n怕把你惊醒\n也怕这一刻溜走\n\n[outro]\n(Vocal-Perf: Fades with layered falsetto \"Yeah yeahs\" and ad-libs.)\n(Inst: Instruments slowly fade out, leaving shimmering reverb tails from the electric guitar and vocals.)\n(Chords: Ebmaj7 - Gm - F - Bb)\n留一点\n嗯嗯嗯嗯\n留一点给我\n嗯嗯嗯嗯\n留一点\n嗯嗯嗯嗯\n留一点给我\n嗯嗯嗯嗯",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：温旧的米白与褪色的芥末黄占据画面大部分，边缘渗入一道淡淡的灰蓝，像一件被洗旧的毛衣纤维在光线下透出的颜色，整体散发出安静、克制却难以割舍的留恋感。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
