  "prompt": "Genre: Mandopop / Cinematic / Chinese Opera Fusion; BPM: 74; Key: E minor; Rhythm: Slow 4/4 ballad, piano-driven; sparse, powerful percussion enters late; on-the-grid feel.; Instruments: Grand piano (reverb-heavy); solo cello (close-mic'd); orchestral strings (lush, wide); cinematic percussion; banhu (expressive); synth pads.; Vocals: Female: ethereal, airy, controlled, minimal vibrato, clean reverb; Male opera (Hualian) guest vocal.; Melody: Ascending arch peaks mid-phrase, resolves down to tonic; legato.; Mood: A lone figure on a vast, empty stage after the final curtain falls, lights dimming.; Production: High-fidelity, cinematic polish; wide stereo field; transparent compression, lush reverbs.; Language: Chinese; Highlight: The abrupt shift from the polished pop chorus to the raw, traditional Male Chinese opera vocal chant, breaking the song's established form.",
  "title": "骨中灯",
  "lyrics": "[intro]\n(Mix: Wide stereo, high-fidelity cinematic mix. Piano centered with broad reverb. Strings occupy full width. Cello slightly panned left. Transparent master bus compression.)\n(Inst: Solo piano arpeggios, followed by solo cello with expressive bowing, lush string orchestra swells.)\n(Hook-DNA: Rhythmic pattern: flowing 16th-note arpeggios. Pitch anchor: circles chord tones, resolves on root. Repetition: pattern transposes with chord changes.)\n(Transition: Cello melody hangs, sustained string chord fades into verse vocal.)\n\n[verse]\n(Melody-Contour: Relatively narrow range, stepwise motion; phrases are long, ending on stable chord tones; speech-like rhythm.)\n(Chords: Em - C - G - D - Am - G - C - D)\n(Vocal-Perf: Airy, breathy chest voice, mezzo-piano, very little vibrato.)\n(Inst: Piano continues arpeggios, strings hold long pads.)\n凿过幽岩 才知玉藏在内里\n谁让宝石生来沉默\n踩过焦土 才知根扎在更深\n谁让大树向来无声\n淬过寒刃 才知锋刃是自身\n谁让利器爱惜锋芒\n熬过长夜 才知黎明是哪种颜色\n谁让深渊养出眼力\n(Transition: String section swells, builds intensity into the chorus.)\n\n[chorus]\n(Melody-Contour: Ascending arch, wide leaps to high notes; peaks on downbeat of 3rd bar; long sustained notes.)\n(Melody-Harmonic-Tension: Melody soars to the 9th over the IV chord, holding for a full measure, creating an open, yearning tension before resolving down to the 5th.)\n(Hook-Recall: The rhythm of the main vocal phrases mimics the long-held notes and release of the intro's cello theme.)\n(Chords: C - G - D - Em - C - G - Am - D)\n(Vocal-Perf: More open and projected tone, mezzo-forte, slight increase in controlled vibrato on sustained notes.)\n(Inst: Full orchestra enters, cinematic percussion (deep toms, cymbals) emphasizes beat 1 of each bar.)\n(Mix: Stereo image widens significantly; percussion adds low-end weight.)\n我把骨头燃成灯\n照清来路也照冷\n看那褪色的山河依然挣\n千锤打出这一声\n不是为谁开了镜\n是这火从骨缝里醒\n(Transition: Percussion and full orchestra cut out, leaving a single piano chord to transition into the quieter second verse.)\n\n[verse 2]\n(Melody-Contour: Similar to first verse, narrow range, stepwise motion; phrases are slightly shorter.)\n(Chords: Em - C - G - D - C - D - Em)\n(Vocal-Perf: Returns to breathy, intimate delivery, but with slightly more forward placement.)\n(Inst: Stripped back to piano and solo cello weaving counter-melodies.)\n断过羽翼 才知飞是腰劲撑起\n谁让天空不肯搀扶\n舍过至亲 才知重是另一种轻\n谁让放手之后无声\n(Transition: Massive orchestral and percussive swell, full stop silence for one beat.)\n\n[bridge]\n(Melody-Contour: Chanted, speech-rhythm; follows traditional opera contours, not Western melodic arcs.)\n(Melody-Harmonic-Tension: The opera vocal uses a traditional pentatonic scale, creating stark modal contrast against the nearly absent harmony. Tension comes from the stylistic clash and raw vocal timbre.)\n(Chords: Static drone on E with percussion)\n(Vocal-Perf: Male opera vocal (Hualian), powerful, raw, declamatory style. Unprocessed, as if in a large hall.)\n(Inst: Traditional Chinese opera percussion, Banhu enters with a piercing melody line.)\n(Mix: Mix flattens, becomes more mono-focused and raw, simulating an older recording style.)\n铁甲寒 霜雪漫 刀未钝 心未散\n心未散 志弥坚 枯藤木 犹参天\n鼓三声 阵前站 生死关 过了岸\n过了岸 身无恙 烈火中 淬出钢\n(Transition: Opera percussion cuts, a huge reverb tail from the final shout leads into the final chorus.)\n\n[chorus]\n(Melody-Contour: Same as first chorus but with higher dynamic intensity and slight melodic variations in the final phrase.)\n(Melody-Harmonic-Tension: Revisits the 9th over the IV chord, but the vocal holds it longer and with more power, and the orchestra adds a dissonant harmony, heightening the tension before final resolution.)\n(Hook-Recall: Vocal rhythm strongly recalls the cello theme, now at maximum emotional intensity.)\n(Chords: C - G - D - Em - C - G - Am - D - E)\n(Vocal-Perf: Full power, forte, sustained high notes with full, expressive vibrato.)\n(Inst: Full orchestra, pounding cinematic percussion, Banhu soaring over the top.)\n(Mix: Widest and loudest point of the song; sidechain compression on orchestra from the kick and vocal.)\n我把骨头燃成灯\n照清来路也照冷\n看那褪色的山河依然挣\n不问烈焰从哪生\n不问黑暗压几层\n是这灯从来没熄灭过\n(Transition: Music abruptly cuts on the final word, leaving only the piano and vocal reverb tail.)\n\n[outro]\n(Melody-Contour: No vocal melody, instrumental fade.)\n(Inst: Solo piano plays a final, sparse arpeggio, echoing the intro motif. A single, long string chord fades to silence.)\n(Mix: Rapid decay of all elements, reverb tails become the focus, fading to complete silence.)",
  "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：深邃的炭黑底色中心燃起一团极克制的琥珀橘红，边缘向外漫渗成暗赭石与灰褐，最外层过渡为沉静的夜蓝灰——如同厚重岩层内部悄然积蓄了数百年的热度，从裂缝处透出微光，不是爆发，是隐忍的燃烧。\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。",
