  "prompt": "Genre: Modern Classical, Neo-Romantic Solo Piano; BPM: 136; Key: C Major; Rhythm: Expressive, free-flowing rubato; rhythm defined by cascading arpeggios and lyrical, non-metronomic melodic phrasing, accelerating and decelerating for emotional emphasis; Instruments: Grand piano; close-mic'd, capturing felt hammer attack, string resonance, and damper pedal noise; recorded in a reverberant concert hall; Vocals: Instrumental, no vocals; Mood: The feeling of reading an old, heartfelt letter by a window on a rainy afternoon, dust motes dancing in the dim light; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end; wide stereo image of the piano; natural hall reverb; minimal compression to preserve full dynamic range; Highlight: The explosive, dissonant ascending arpeggio in the bridge, a blur of notes resolving unexpectedly into a powerful, resonant tonic chord, creating a moment of pure catharsis.",
  "title": "Ink Kept Drinking",
  "lyrics": "[intro]\n(Mix: Wide stereo piano image, prominent natural hall reverb with long tail. Focus on realism: felt hammer attack, damper pedal sounds, and sympathetic string resonance are audible. Minimal transparent compression to control peaks without sacrificing dynamics.)\n(Inst: Grand piano, right hand plays a delicate, questioning melody in the upper-middle register. Left hand provides sparse, arpeggiated chords.)\n(Hook-DNA: A simple 3-note motif (G-A-E); repeats twice with slight rhythmic variation, the second time resolving down to the 3rd of the tonic chord.)\n(Melody-Contour: A gentle arch, ascending from 5 to 6 then descending to 3.)\n(Chords: Cmaj7 - G/B - Am7 - Gsus4)\n\n[verse]\n(Inst: Piano melody becomes more lyrical and continuous, with longer phrases. Left hand transitions to flowing sixteenth-note arpeggios, covering a wider range.)\n(Vocal-Perf: Instrumental melody acts as vocal, phrased with breath-like pauses between longer melodic statements, building intensity.)\n(Melody-Rhythm: Phrases begin on the 'and' of beat 4, creating a gentle push into each new bar. Sustained notes are held over the bar line.)\n(Melody-Contour: A long, stepwise ascending line that builds tension over two phrases.)\n(Chords: Fmaj7 - C/E - Dm7 - Am7 - Gsus4 - G)\nThe paper holds the shape of your handwriting,\nEach loop and crossing caught mid-vanishing —\nThe ink has been drinking from time,\nWord by word, a slow, unwitnessed thinning.\nI press my thumb where the margin ends,\nAnd something deeper than the stain begins.\n\n[chorus]\n(Inst: Piano dynamics swell to forte. Right hand plays the main theme with fuller, octave-reinforced chords. Left hand plays powerful, resonant bass notes and full chords. Heavy use of the sustain pedal to create a lush wash of sound.)\n(Mix: The overall level and perceived room size increase. Reverb tail is more pronounced.)\n(Hook-DNA: A broad, powerful melodic statement; rhythm uses whole notes for two bars for grandeur, followed by a cascading sixteenth-note run; motif anchors on the high G (the 5th); repeats once with fuller left-hand chord voicings.)\n(Melody-Harmonic-Tension: The melodic peak lands on the 9th (D) over the tonic Cmaj7 chord, held for two full beats, creating a bright, beautiful tension before resolving downwards.)\n(Chords: C - G/B - Am - Am/G - Fmaj7 - C/E - Dm7 - Gsus4 - C)\nThe rain writes back against the glass,\nA language the window will never pass —\nEvery drop an answer trying to land,\nLonging has the weight of unplanned.\nDust hangs still in the slant of grey,\nOnly seen when the light bends a certain way —\nEven grief needs a reason to show,\nEven sorrow needs somewhere to glow.\n\n[bridge]\n(Inst: A dramatic shift in character. The piece becomes turbulent and passionate. Fast, virtuosic runs in the right hand over agitated, low-register chords in the left.)\n(Melody-Harmonic-Tension: Modulates to the relative minor (A minor). The melody insistently uses chromatic passing tones and centers around the tense tritone interval against the dominant chord, creating a feeling of desperate searching before resolving via a massive arpeggio back to G7.)\n(Chords: Am - E/G# - Gdim7 - F#m7b5 - Dm/F - E7sus4 - E7 - G7)\nI can't fold you back into the envelope,\nCan't unknow the afternoon this broke —\nTime is not a wound that seals,\nIt is the scar that slowly reveals.\nDust also has its moment of falling,\nEven the settled things keep calling.\n\n[verse 2]\n(Inst: After the bridge's storm, the dynamic drops to piano. The melody is a quiet, contemplative variation of the first verse theme, played an octave higher, sounding more fragile. Left hand plays sparse, bell-like chords.)\n(Chords: Fmaj7 - C/E - Dm7 - Gsus4 - G)\nThe letters thin but longing fills the thinning,\nMore weight arrives where words are disappearing —\nWhat the ink surrenders, I keep,\nWhat the afternoon forgets, I steep.\n\n[chorus 2]\n(Inst: The final, grandest statement of the theme, played fortissimo. Right hand plays the melody in thick octaves. Left hand plays huge, spread-out arpeggios from the lowest register to the middle. The sustain pedal is fully engaged.)\n(Mix: The loudest point of the piece. The mix feels huge and immersive.)\n(Hook-DNA: The same theme as the first chorus, but the final cascading run is extended and leads to a higher climactic note.)\n(Melody-Harmonic-Tension: The same melodic tension on the 9th occurs, but this time the resolution is delayed by an extra bar of cascading arpeggios, heightening the eventual cathartic release.)\n(Chords: C - G/B - Am - Am/G - Fmaj7 - C/E - Dm7 - Gsus4 - C)\nThe rain writes back against the glass,\nA language the window will never pass —\nEvery drop an answer trying to land,\nLonging has the weight of unplanned.\nDust hangs still in the slant of grey,\nOnly seen when the light bends a certain way —\nDust also has its settled, final weight,\nSome sorrows arrive precisely late.\n\n[outro]\n(Inst: A long ritardando (slowing down). Fragments of the introductory motif are played very quietly (pianissimo), with long pauses between them. The final chord is a soft, high-register Cmaj7, held until it fades completely into the reverb.)\n(Mix: The direct sound of the piano fades, leaving only the long, lush hall reverb tail for the final seconds.)\n(Chords: Fmaj7 - C/E - Dm7 - Cmaj9)",
  "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：以沉郁的铅灰蓝为主色调，中段渗入一道极淡的琥珀黄——如同阴雨午后某一刻光线短暂破云而入，打在粗糙纸面上的瞬间；底层隐约可见一道近乎消失的暖白色渍痕，像是褪色墨水在棉布上被时间饮干之后留下的痕迹轮廓，而非字迹本身。\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。",
