  "prompt": "Genre: Mandopop Ballad; BPM: 75; Key: F minor; Rhythm: Simple half-time pop groove; kick 1, snare 3; straight 8ths; firmly on-the-grid feel; Instruments: Strummed steel-string acoustic; clean electric guitar licks; round DI electric bass; programmed drum kit; Vocals: Male; clear mid-range tenor; slightly nasal timbre; earnest delivery with gentle vibrato on phrase-ends; clean pop processing; Melody: Narrow verse melody; chorus leaps octave at start then descends; Mood: Watching the last bus pull away from a rainy stop, knowing you're not on it; Production: Clean, direct, mid-focused mix; moderate stereo width; light plate reverb for space; Language: Chinese; Highlight: The octave-leap vocal on the first word of the chorus, contrasting sharply with the verse's narrow, conversational range.",

  "lyrics": "[intro]\n(Hook-DNA: The core motif is a simple acoustic guitar melody; rhythm is a repeating dotted-eighth + sixteenth figure; pitch circles the 3rd and 5th of the tonic chord; the motif repeats over the chord progression.)\n(Inst: Two clean acoustic guitars; one strumming chords, one playing the lead melody line. Slight finger noise.)\n(Mix: Mid-focused, clean, direct sound. Not glossy or wide. Bass and kick centered. Guitars panned slightly L/R. Light plate reverb creates a small room ambiance.)\n\n[verse]\n(Transition: Full rhythm section (bass and drums) enters with the vocal on the downbeat.)\n(Inst: Strummed acoustic guitars, clean electric bass playing root notes, simple programmed drums.)\n(Vocal-Perf: Soft, conversational chest voice, mezzo-piano. Mostly straight tone with little vibrato.)\n(Melody-Contour: Narrow range, primarily stepwise motion; phrases land on stable chord roots; on-the-beat delivery.)\n(Chords: Fm - Db - Ab - Eb)\n你走后那把椅子压着一道光\n灰尘落在上面慢慢把边缘藏\n我没把它挪动怕惊碎那个方向\n时间绕着它走圈我站在圈子旁\n\n[pre-chorus]\n(Transition: A single, gentle cymbal crash marks the section change, energy remains consistent.)\n(Inst: Full band continues.)\n(Vocal-Perf: Dynamics build subtly from mezzo-piano to mezzo-forte, a sense of anticipation.)\n(Melody-Contour: Gently ascending line; phrases remain short and conversational but gain intensity.)\n(Chords: Fm - Db - Ab - Eb)\n说忘记太容易说记得又太烫\n有些话压在喉咙里越积越重量\n想假装日子照常想撑起这堵墙\n偏偏最熟悉的风还带着你的香\n\n[chorus]\n(Transition: Clear dynamic lift into the chorus; vocals jump up an octave creating an emotional shift.)\n(Hook-Recall: The vocal melody takes over as the primary hook, defined by its large melodic leap.)\n(Melody-Harmonic-Tension: The melody's octave leap on \"不\" lands powerfully on the 5th over the tonic chord (Fm), creating a strong declaration. Tension resolves downwards through the iv-V-i cadence at the end of the phrase.)\n(Inst: Full band plays with more energy. A subtle shaker is added.)\n(Vocal-Perf: Higher register, more open and forceful (mezzo-forte). Controlled vibrato at the end of phrases. A slight, emotive strain on the highest notes.)\n(Melody-Contour: Wide-ranging arch starting with an octave leap; followed by a stepwise descent; phrases are long and flowing.)\n(Chords: Fm - Db - Ab - Eb - Bbm - C7 - Fm)\n不是没试过松手放开\n是松开之后更想把你拽回来\n爱一旦开了缝\n风就什么都吹进来\n我不怕孤独只怕这个空间\n空的刚好装得下你离开的姿态\n反复折叠那一天\n连呼吸都压得不太对拍\n\n[verse]\n(Transition: Music drops back to the verse dynamic, led by the acoustic guitar.)\n(Inst: Clean electric guitar enters, playing sparse, melodic counter-lines.)\n(Vocal-Perf: Delivery is slightly more intense than the first verse, carrying emotion over from the chorus.)\n(Melody-Contour: Gently ascending line; phrases remain short and conversational but gain intensity.)\n(Chords: Fm - Db - Ab - Eb)\n你说过的那些话贴在某处墙\n我不敢靠太近又舍不得遗忘\n学着把笑挂出来学着把灯开亮\n却在最安静的角落里心跳着慌\n\n[chorus]\n(Transition: Another powerful dynamic lift into the final chorus.)\n(Mix: Fullest part of the mix. Stereo field feels slightly wider due to electric guitar parts.)\n(Hook-Recall: The vocal melody's octave leap hook returns with maximum emotional weight.)\n(Melody-Harmonic-Tension: The melody's octave leap on \"不\" lands powerfully on the 5th over the tonic chord (Fm), creating a strong declaration. Tension resolves downwards through the iv-V-i cadence at the end of the phrase.)\n(Inst: All instruments playing at peak energy. Electric guitar counter-melodies are more active.)\n(Vocal-Perf: Most powerful delivery of the song. Sustained high notes have more pronounced vibrato.)\n(Melody-Contour: Wide-ranging arch starting with an octave leap; followed by a stepwise descent; phrases are long and flowing.)\n(Chords: Fm - Db - Ab - Eb - Bbm - C7 - Fm)\n不是没试过松手放开\n是松开之后更想把你拽回来\n爱一旦开了缝\n风就什么都吹进来\n我不怕孤独只怕这个空间\n空的刚好装得下你离开的姿态\n反复折叠那一天\n连呼吸都压得不太对拍\n\n[outro]\n(Transition: Instruments begin to fade out one by one after the final vocal line.)\n(Inst: The rhythm section and strummed acoustics fade, leaving the clean electric guitar to play a final, lingering melodic phrase over the sustained final chord.)\n",
  "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：深蓝灰与浑浊赭石之间的沉默地带，像某种被按住、未能散开的重量——低饱和的蓝紫色底层压着一道隐约的暖黄渗透，像一块被长期搁置的空间里透进来的唯一一缕光，光没有方向感，只是存在在那里。\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。",
