  "title": "钝口",
  "lyrics": "[intro]\n(Chords: C#m - A - E - B)\n(Inst: Lyrical cello melody playing a melancholic theme over a sparse, arpeggiated grand piano.)\n(Mix: Intimate and spacious, setting a reflective tone with heavy room reverb on the cello.)\n\n[verse]\n(Chords: C#m - G#m - A - E - F#m - C#m - A - B)\n(Vocal-Perf: Conversational, breathy, mezzo-piano, gentle phrasing, narrative focus.)\n(Inst: Vocals and piano dominate. A simple, clean bass line enters, providing a subtle pulse. Acoustic guitar strums lightly in the background.)\n(Melody-Rhythm: Flowing and speech-like, following the lyrical cadence.)\n窗台上那盆植物黄了半边\n我一直没有浇水也没有剪掉\n你上次来的时候说它快撑不住\n我说嗯然后换了个话题\n\n(Transition: Piano chords build slightly in volume, a single cymbal swell leads into the chorus.)\n[chorus]\n(Chords: E - B/D# - C#m - G#m - A - E - F#m - B)\n(Vocal-Perf: Dynamic lift to mezzo-forte, powerful and emotionally resonant chest voice, controlled belting on the hook.)\n(Inst: Full band enters. A solid, half-time drum beat with a crisp snare on beat 3. Cello plays long, supportive notes. Piano shifts to strong block chords.)\n(Melody-Contour: The melody ascends dramatically on the opening line, creating the song's signature emotional peak.)\n话到嘴边就钝了\n钝在你皱眉的那一秒我选了沉默\n话到嘴边就钝了\n钝在所有能挽回的时机里我缩了\n爱得越深越钝\n最后连哭都哭得缩手缩脚\n你在等我开口\n话到嘴边就钝了\n\n(Transition: The final chord of the chorus rings out, and the energy immediately drops for the bridge.)\n[bridge]\n(Chords: A - B - G#m - C#m - F#m - G#m - A - B)\n(Vocal-Perf: Intensity builds again from introspection to desperation. The delivery becomes more urgent.)\n(Inst: A clean electric guitar plays arpeggiated fills. Drums become slightly more complex with subtle hi-hat patterns. The harmony creates tension.)\n(Mix: The stereo field widens as more instrumental layers are introduced.)\n那植物最后还是枯了\n我站在那里盯着看了很久\n不知道在等什么\n不知道在等谁\n\n(Transition: A powerful drum fill and a sustained vocal note launch into the final chorus.)\n[chorus]\n(Chords: E - B/D# - C#m - G#m - A - E - F#m - B)\n(Vocal-Perf: Full forte, peak emotional delivery, slight vocal fry and strain for authenticity. Ad-libbed harmonies may appear.)\n(Inst: All instruments at maximum energy. Distorted electric guitar enters, playing long, soaring notes. Crash cymbals accent the downbeats.)\n(Mix: The mix is dense and powerful, creating a climactic wall of sound. Vocals are right at the front, driving the emotion.)\n话到嘴边就钝了\n钝在你背影消进电梯缝里那一刻\n话到嘴边就钝了\n钝在后来再见面我只会点头笑着说\n爱过你才这么钝\n把所有利的地方磨成了圆角\n现在连恨都恨得\n绵软无力开不了口\n\n[outro]\n(Chords: A - Am - E)\n(Vocal-Perf: Returns to a soft, breathy whisper. Delivery is resigned and sorrowful.)\n(Inst: The full band cuts out, leaving only a sparse piano playing the final chords. A final, lingering cello note fades out.)\n(Structure: Decelerando and fade to silence.)\n还是钝的\n还是钝的\n开不了口",
  "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：大面积灰褐与消退的暖黄在画布中段缓慢交叠，像某种曾经发过光的东西正在冷却但还没有彻底暗下去——不是愤怒，不是眼泪，是那种想说又咽回去的钝痛，颜色浓的地方像淤青，稀薄处透出底布原色像皮肤。整体低饱和，边缘无法收拢，向四角渗散。\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。",
