  "prompt": "Genre: Cinematic Orchestral / Modern Classical; BPM: 164; Key: D minor; Rhythm: Starts with a free-form rubato feel carried by rapid 16th-note piano arpeggios, transitioning into a grand, flowing orchestral pulse in a broad 4/4, driven by a brain-scratching melodic hook in the legato string phrases and timpani; Instruments: Closely-mic'd concert grand piano with felt hammer detail, full string orchestra with audible bow texture, warm legato french horns, soaring flutes/oboes, resonant hall timpani; Vocals: Instrumental (no vocals); Mood: Standing on a cliff overlooking a vast, misty valley at sunrise, a feeling of immense history and personal destiny converging in a single, silent breath.; Highlight: The downbeat at 2:07 where the full orchestra erupts into a fortissimo restatement of the main theme after a tense, syncopated build, providing a powerful, cathartic release.",
  "title": "Fault Line Rising",
  "lyrics": "[intro]\n(Mix: High-fidelity capture of a live orchestra in a large concert hall. Vast stereo image with deep, natural reverb. Dynamics are extremely wide with minimal compression. Frequency balance is natural and acoustic, focusing on the rich midrange of the instruments.)\n(Inst: Solo concert grand piano, closely-mic'd to capture string resonance and felt hammer attack.)\n(Melody-Contour: Wide-ranging, cascading arpeggios and scalar runs. Texture over melody.)\n(Melody-Rhythm: Free-form, rubato. A fluid cascade of 16th and 32nd notes with expressive, unmetered phrasing.)\n(Chords: Dm - Gm - C - F - Bb - Edim - A7 - Dm)\nA mountain range moves a billion years\nand never once appears to move at all\n\n[chorus]\n(Hook-DNA: Rhythmic pattern is a long, held note on beat 1 followed by an eighth-note flourish; anchors resolution on the tonic D; motif repeats over a 4-bar phrase with rising orchestration.)\n(Melody-Contour: Ascending theme with a dramatic leap of a minor 6th to its peak, followed by a stepwise descent.)\n(Melody-Rhythm: Stately and legato, main melodic notes land on downbeats, giving a powerful, declarative feel.)\n(Melody-Harmonic-Tension: Melody peaks on the 6th over the subdominant (iv) chord, creating a moment of bright hope before resolving back to the tonic minor.)\n(Inst: High violins on main theme, low strings provide harmonic foundation, french horns on counter-melody, piano arpeggios underneath.)\n(Mix: Full orchestra enters, widening the stereo field significantly. Piano becomes supporting texture.)\n(Chords: Dm - Gm - C7 - F - Bb - A7sus4 - A7 - Dm)\nThe peaks are still growing\nEvery summit a wound pressed shut by stone\nThe range still rising\nAll the weight of every broken seam we own\nThe peaks are still growing\nCarrying what no stone has ever known\n\n[verse]\n(Melody-Contour: Lyrical, gentle arch shape, moving mostly stepwise. More intimate and contained range than chorus.)\n(Melody-Rhythm: Softer phrases, lead melody played with more rhythmic freedom against the steady string accompaniment.)\n(Inst: Solo oboe and flute carry the melody, string section provides lush, sustained pads, harp adds delicate arpeggiated flourishes.)\n(Mix: Dynamics drop to piano/mezzo-piano. Sonic focus narrows to the solo woodwinds.)\n(Chords: Gm7 - C7 - Fmaj7 - Bbmaj7 - Em7b5 - A7 - Dm)\nI drag one nail across the grooved stone face\nA furrow packed with ochre dust and years\nThe character beneath resists the light\nuntil the scraping opens what persists\nThe fog line cuts the valley perfectly in half\nHalf the world still sleeping\nhalf already standing in the cold\n\n[bridge]\n(Melody-Harmonic-Tension: A repeating, ascending chromatic motif in the strings builds severe tension against a low pedal point in the basses and cellos. The phrase ends on a dissonant V7(b9) chord, leaving the harmony completely unresolved and demanding the chorus.)\n(Inst: Orchestra builds in layers. Brass section becomes prominent. Timpani rolls and cymbal swells intensify, creating a dramatic crescendo.)\n(Mix: Massive crescendo from mezzo-forte to fortissimo. The mix becomes dense and saturated.)\n(Chords: A7sus4 - A7 - Bb - C/Bb - Dm/A - A7(b9))\nAll the peaks are healed fractures\npressure locked into an upward scar\nI am not the stone\nI am the fault line\nstill in motion\nAll the shapes the wounded ground makes reaching for the dark\n\n[chorus]\n(Hook-DNA: Rhythmic pattern is a long, held note on beat 1 followed by an eighth-note flourish; anchors resolution on the tonic D; motif stated once in its most powerful form.)\n(Melody-Contour: The same ascending theme from the first chorus, but played in a higher octave with maximum intensity.)\n(Melody-Rhythm: The stately legato rhythm is now aggressively punctuated by the full orchestra.)\n(Melody-Harmonic-Tension: The tension built in the bridge is cathartically released on the downbeat of the powerful D minor tonic chord. The melody soars with triumphant finality over the harmony.)\n(Inst: Full orchestra tutti at fortissimo. Soaring high violins, powerful brass fanfare, crashing cymbals, pounding timpani.)\n(Mix: Dynamic peak of the piece. Maximum stereo width, depth, and volume.)\n(Chords: Dm - Gm - C7 - F - Bb - A7sus4 - A7 - Dm)\nThe peaks are still growing\nEvery summit a wound pressed shut by stone\nThe range still rising\nAll the peaks are where the old breaks finally hold\nThe peaks are still growing\nI pass nothing forward but the fault line\nand the bone\n\n[outro]\n(Inst: Orchestra deconstructs. Fragments of the main theme are passed between solo flute, french horn, and finally piano.)\n(Melody-Contour: Melodic fragments descend in pitch and slow in tempo.)\n(Mix: A long, gradual diminuendo to silence. The concert hall's reverb tail becomes the final sound.)\n(Chords: Dm - Gm6 - A7 - Dm)\nA name under the silt\nA year no one remembers now\nThe wrong date cut in stone\nhas been the only record kept\nand somehow that is all\nthe mountain ever meant",
  "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：深沉的铁灰色与锈赭色在画布中央形成一道水平压痕，仿佛亿万年地壳挤压后留下的愈合线迹，上半部分是冷蓝灰的雾气渗透层，下半部分是暗褐泥土色的沉积感，两色之间存在一道极细的亮琥珀色裂隙，如同断层带内部逸出的微光。\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。",
