  "lyrics": "[intro]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Solo grand piano playing a simple, melancholic motif based on the chorus melody. A touch of lush reverb.)\n(Mix: Centered, intimate, spacious.)\n(Melody-Contour: Gentle descending line.)\n\n[verse]\n(Chords: Cm - Ab - Eb - Bb)\n(Vocal-Perf: Conversational, gentle chest voice. Mezzo-piano. Clear diction with minimal vibrato.)\n(Inst: Piano continues with simple chords. A subtle, clean electric bass enters, holding root notes. A simple kick drum pattern on beats 1 and 3.)\n(Mix: Vocals remain front and center, piano and bass create a warm bed. Still intimate.)\n(Transition: A soft string pad swells quietly in the last two bars.)\n你削苹果总是从蒂开始\n我从底部下刀\n同一个果子削出两种纹路\n\n[pre-chorus]\n(Chords: Ab - Ab - Eb - Bb)\n(Vocal-Perf: Intensity builds slightly. A sense of urgency enters the voice. Dynamics rise to mezzo-forte.)\n(Inst: The full drum kit enters with a driving backbeat on the snare. Hi-hats play steady 8th notes. The string pad becomes more prominent.)\n(Mix: The stereo field begins to widen. Drums add punch and drive.)\n(Sound-Design: A subtle reverse cymbal swell leads into the chorus.)\n饭桌上的安静\n比争吵更烫\n各自看着手机屏幕假装在忙\n同一屋顶下住成了两个方向\n\n[chorus]\n(Chords: Eb - Bb - Cm - Ab)\n(Vocal-Perf: Full power, soaring tenor in a higher register. Sustained notes with controlled, emotional vibrato. Forte.)\n(Inst: Full band explosion. Wide, powerful piano block chords. Soaring, distorted electric guitar plays melodic fills in response to vocal phrases. Drums are powerful and driving.)\n(Mix: Stadium-sized width. Lush reverb on vocals and snare. Guitar fills panned wide.)\n(Melody-Harmony: Strong, anthemic melody focusing on chord tones.)\n明明手还交叠着\n心跳却对不上拍\n温度从指尖漏光\n剩下姿势撑门面\n明明嘴角还弯着\n眼神已经飞出窗外\n是谁先学会了\n用笑容替伤口盖章\n盖不住的败\n\n[bridge]\n(Chords: Ab - Eb - Bb - Cm, Ab - Eb - Bb - Bb)\n(Vocal-Perf: A dynamic drop. Vocals become more tender, almost pleading, with an airy quality. Builds back up at the end.)\n(Inst: Arrangement strips back to just piano and the lush string pads. Bass holds long, sustained notes. Drums drop out completely.)\n(Mix: Space opens up around the vocal. A very wide, cinematic feel.)\n(Transition: A powerful, rolling drum fill brings the full band back for the final chorus.)\n我试过\n把棱角磨圆\n把脾气塞进肋骨夹缝\n可越是小心翼翼\n越是把你我磨成陌生\n\n[chorus]\n(Chords: Eb - Bb - Cm - Ab)\n(Vocal-Perf: Maximum emotional intensity. Vocals are pushed to the edge, with tasteful ad-libs and runs over the main melody. Fortissimo.)\n(Inst: Everything from the first chorus, but bigger. Cymbals crash more frequently. The lead guitar part is more aggressive and constant. A high string counter-melody is added.)\n(Mix: The biggest point of the song. All elements are loud and clear, heavily compressed for maximum impact.)\n明明手还交叠着\n心跳却对不上拍\n温度从指尖漏光\n剩下姿势撑门面\n明明嘴角还弯着\n眼神已经飞出窗外\n是谁先学会了\n用笑容替伤口盖章\n盖不住的败\n\n[outro]\n(Chords: Cm - Ab - Eb)\n(Vocal-Perf: The final two lines are delivered with a sense of resignation, fading out with a long reverb tail.)\n(Inst: The band cuts out, leaving only a final, sustained piano chord and the reverb tail of the last cymbal crash.)\n(Mix: Rapidly decays to silence, leaving just the vocal and piano reverb.)\n是谁先学会了\n用笑容替伤口盖章\n盖不住的败",
  "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：大面积沉郁的石板灰自上而下压落，中段渗出一层极薄的旧象牙白，像被反复擦拭却擦不干净的雾气，最底部积出一道暗而钝的赤褐——不是血的鲜烈，是铁锈的疲倦。整体传递出一种表面平整、内里持续渗漏的压抑张力，如同一张脸在维持表情时悄悄崩塌的瞬间。\n\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\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。",
