  "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": "Grain in the Stone",
  "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 deed pressed under stone — the grain runs both ways\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 mist does not rise — it parts along the valley floor\nSomething older than my name has cleared this path before\nThe mountain knows my face, the stone was warm before I came\nI am not walking toward — I am the walk, the blood, the grain\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)\nA deed sits folded under a weight of cliff-veined stone\nNo hand explained it, no voice said why it was placed alone\nBefore the sun had breached the ridge the rock felt cold beneath my heel\nThen came the warmth — deeper than skin — no sunrise could reveal\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))\nThe canyon wind collapsed to nothing — sudden, absolute\nAnd from inside my ears a drumbeat rose to fill the mute\nNot me who chose this ledge — the ledge has always held my weight\nEvery soul believed it chased the hour — the hour stood and waited at the gate\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 mist does not rise — it parts along the valley floor\nSomething older than my name has cleared this path before\nThe mountain knows my face, the stone was warm before I came\nI am not walking toward — I am the walk, the blood, the grain\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)\nThe deed beneath the stone — the grain runs both ways still",
  "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：深沉的赭石棕与冷灰蓝在画面中央缓慢相遇，边缘向外渗出极淡的曙光金色，仿佛两块不同地质年代的岩层在光线初透时显露出相同的纹路走向，整体气质沉厚而悠远，带有史诗般的地质时间感与内敛的命运重量。\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。",
