  "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": "Still Ground",
  "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)\nI stand at the highest point\nNot knowing if this is the beginning or the fall\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)\nFeet press the ground, chest hangs in the air\nThe horizon tilts but I do not move\nI stand at the highest point\nIs this where I rise, or where I fall through?\nBoth truths tear me open at the seam\nStill ground beneath a weightless dream\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)\nThe breath I held has no place left to go\nMy ribs are walls around a hollow bell\nSomething massive turned\nand I was already past the edge before I knew\nThe body lands precisely where the soul already fell\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))\nIt is not that I do not know\nIt is that both are true at once\nAscent and ruin\nsharing the same moment, the same bones\nI did not choose — I was already chosen\nand the only witness was my own held breath\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)\nFeet press the ground, chest hangs in the air\nThe horizon tilts but I do not move\nI stand at the highest point\nIs this where I rise, or where I fall through?\nBoth truths tear me open at the seam\nStill ground beneath a weightless dream\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 valley below holds no answer\nonly the echo of a breath I never released",
  "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：深哑灰蓝与冷铅色在画布中心缓慢叠压，顶部边缘透出一道极窄的苍白光缝，如同黎明前最后一秒的天际线——既非黑夜也非白昼，悬停在两种状态的临界处；底部沉积着暗紫棕色的厚重色层，仿佛大地的引力正从画布深处向下拉拽。整体传递出「身体站定、灵魂已悬空」的物理悖论感。\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。",
