  "lyrics": "[intro]\n(Mix: High-fidelity, transparent mix. Wide stereo field. Guzheng slightly off-center, strings create a wide pad. Soft kick and bass centered. Gentle bus compression. Lush hall reverb with long tail on guzheng.)\n(Inst: Solo Guzheng playing a pentatonic arpeggio motif. Soft string pads enter.)\n(Hook-DNA: Rhythmic pattern: eighth note arpeggio figure with a dotted-quarter feel on the downbeat. Pitch anchor: circles around the tonic and dominant of Am. Repetition structure: motif repeats with slight variation, establishing a calm loop.)\n(Transition: String pad swells slightly, leading into the vocal entry.)\n\n[verse]\n(Inst: Simple synth bass on downbeats. Soft electronic kick and shaker establish a slow groove. Guzheng plays fills.)\n(Vocal-Perf: Very soft, airy chest voice, almost spoken, mezzo-piano.)\n(Chords: Am - G - C - G - F - G - Em - Am)\n(Melody-Contour: Narrow range, mostly stepwise motion, gentle rising and falling phrases landing on tonic or third.)\n捧一掌清水走向湖边去\n以为倒回去会轻一些\n水从指缝渗进湖面里\n手掌却在变空时灼起\n(Transition: A single guzheng glissando connects to the next section.)\n\n[verse]\n(Inst: Instrumentation consistent with first verse.)\n(Vocal-Perf: Delivery remains soft and airy.)\n(Chords: Am - G - C - G - F - G - Em - Am)\n(Melody-Contour: Similar contour to Verse 1, maintaining the calm narrative feel.)\n我以为放手是一种减轻\n试着松开 指节反而紧\n那些以为握住的光与情\n其实从来就没有真正进\n(Transition: Subtle string swell and a final guzheng phrase lead into the chorus.)\n\n[chorus]\n(Mix: Vocals become more present, slightly increased volume. Stereo field feels wider.)\n(Inst: String section becomes more prominent with sustained chords. Guzheng plays rhythmic arpeggios.)\n(Vocal-Perf: More sustained notes, slightly more open tone but still gentle, mezzo-forte.)\n(Chords: F - G - C - F - G - Am - F - G - Em - Am - F - G - Am)\n(Melody-Contour: Ascending line in the first half, peaking mid-phrase, then descending stepwise.)\n(Melody-Harmonic-Tension: Melody holds the 5th over the Am chord, creating stable poignancy. Melody descends, resolving upwards to the tonic on the final phrase.)\n(Hook-Recall: The relaxed, on-the-beat vocal rhythm directly recalls the steady pulse of the opening guzheng motif.)\n越是轻轻放开\n手心越是发烫\n越是慢慢松手\n抓得越是发慌\n越是静静看它散\n越清楚从没握在掌\n(Transition: The final chord sustains as a Dizi/Xiao flute enters to take over the melody.)\n\n[interlude]\n(Inst: Dizi/Xiao flute plays a lyrical, improvisatory solo melody. Guzheng provides harmonic accompaniment. Rhythm section continues the gentle pulse. String pads hold.)\n(Melody-Contour: Flute melody uses wider leaps and more ornamentation than the vocal, with a free, flowing rhythm.)\n(Transition: The flute solo ends on a long, held note with a slight fall-off, and the strings swell for the final chorus.)\n\n[bridge]\n(Mix: Stripped back to near solo vocal with sparse guzheng. Reverb lengthens. Emotional apex of the song.)\n(Inst: Guzheng plays single plucked notes in the space between vocal phrases. Strings hold a low, quiet pad.)\n(Vocal-Perf: Intimate, slightly raw, controlled vulnerability. Dynamic drop before the final chorus eruption.)\n(Chords: F - G - Em - Am - F - G - Am - G)\n不是放不放得开的事\n是从来就不曾真正拥有\n所以那灼热不是不舍\n是手心记得 从未握够\n越是轻轻放开 手心越是发烫\n(Transition: Strings surge upward into the final full chorus.)\n\n[chorus]\n(Mix: A touch more reverb on the vocals for a more spacious feel.)\n(Inst: Full instrumentation returns. Dizi/Xiao plays subtle counter-melodies in the background.)\n(Vocal-Perf: Emotionally similar to the first chorus, with a touch more emphasis on the final phrases.)\n(Chords: F - G - C - F - G - Am - F - G - Em - Am - F - G - Am)\n(Melody-Contour: Ascending line in the first half, peaking mid-phrase, then descending stepwise.)\n(Melody-Harmonic-Tension: Repeats the tension-release pattern of the first chorus, reinforcing the song's emotional core.)\n(Hook-Recall: The relaxed, on-the-beat vocal rhythm directly recalls the steady pulse of the opening guzheng motif.)\n越是轻轻放开\n手心越是发烫\n越是慢慢松手\n抓得越是发慌\n越是静静看它散\n越清楚从没握在掌\n(Transition: Vocal on the final word is held and fades out with a long reverb tail.)\n\n[outro]\n(Inst: Rhythm section fades out, leaving Guzheng, string pads, and Dizi/Xiao. The arrangement deconstructs.)\n(Vocal-Perf: Vocals are sung more sparsely, echoing the final lines of the chorus, becoming softer and fading away.)\n(Chords: F - G - Em - Am - F - G - Am)\n(Melody-Contour: Short, descending phrases that echo the end of the chorus melody, fading into silence.)\n越是轻轻放开 手心越是发烫\n从没握在掌",
  "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：大面积沉静的灰蓝与浅墨色交叠，中央区域漫出一片极淡的暖焦橙，如同冷水中心悄然升起一点温度，色调克制却隐含灼热感——冷与暖在画布上无声对峙，既非燃烧也非熄灭。\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。",
