  "prompt": "Genre: Chill Trap-Pop; BPM: 95; Key: G Major (relative E minor feel); Rhythm: Slow, half-time trap groove with skittering 16th-note hi-hats and a heavy snare on beat 3; Instruments: Deep 808 sub-bass, reverberant clap/snare, filtered synth pads, distant piano melody, arpeggiated plucks; Vocals: Female, breathy and airy head-voice, intimate close-mic delivery, heavy reverb, and formant-shifted vocal chop melody; Mood: Leaning against a cold window in an Uber at 3 AM, watching blurry city lights pass, club music still a faint ringing in your ears; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Prominent sub-bass, forward vocals, and a wide stereo image. Heavy sidechain compression from the kick; Highlight: The moment the pre-chorus ends and the beat drops into a sparse arrangement of sub-bass and a melancholic vocal chop melody, subverting the expectation of a loud chorus.",
  "title": "Second Skin",
  "lyrics": "[intro]\n(Mix: Deep sub-bass focus, clean mids for vocals, crisp but airy highs. Wide stereo field. Moderate master bus compression. Vocals saturated with long-tail reverb and stereo delay.)\n(Inst: Muted, filtered synth pad. Distant vocal chops with heavy formant shifting and reverb.)\n(Hook-DNA: Vocal chop motif. Rhythmic pattern is a syncopated 3-note phrase. Pitch anchor is the minor 3rd. Repetition structure is a call-and-response pattern between two different pitched chops.)\n(Melody-Contour: The main chop melody follows a descending minor pentatonic line, starting on the 5th and ending on the root.)\n\n[pre-chorus]\n(Mix: A subtle low-pass filter opens up on the synths.)\n(Vocal-Perf: Breathy, intimate close-mic delivery, almost spoken. Low dynamic range.)\n(Inst: Filtered synth pad continues. Kick drum enters with a simple pattern. Subtle riser sfx.)\n(Chords: Em - C - G - D)\n(Melody-Rhythm: Phrases start on the upbeat of 4, creating anticipation. Consistent 16th-note rhythm.)\n(Melody-Contour: Monotonic, repetitive melody, staying close to the root note of each chord.)\nThe posture that I practiced in the hall\nThe version of my voice I gave to all\nA frequency I tuned myself to hold\nTill I forgot the sound before the mold\n\n[chorus]\n(Mix: Wider stereo image. Prominent sub-bass. Heavy sidechain compression on pads from kick, creating a pumping feel.)\n(Inst: Deep 808 sub-bass. Snappy clap on beat 3. Skittering 16th-note closed hi-hats. Main vocal chop melody is central.)\n(Vocal-Perf: Single word sung with heavy reverb, acting as a background texture.)\n(Chords: Em - C - G - D)\n(Hook-DNA: Rhythmic pattern: syncopated 3-note chop phrase on beats 1 and 3. Pitch anchor: resolves to the root at the end of the 4-bar loop. Repetition: The motif repeats identically.)\n(Melody-Harmonic-Tension: Main vocal chop melody uses the 4th over the tonic minor chord, creating a momentary suspension before resolving down to the 3rd, creating a sense of yearning.)\nStretching\n\n[verse]\n(Vocal-Perf: Returns to breathy, intimate style, but with more melodic movement.)\n(Inst: Beat continues from chorus but hi-hats are less dense. A filtered, distant piano melody is introduced.)\n(Chords: Em - C - G - D)\n(Melody-Contour: Ascending line in the first half of a phrase, descending in the second, creating a gentle arch.)\n(Melody-Rhythm: More syncopated and conversational than the pre-chorus. Phrases often end before the bar line.)\nI used to mouth the words before I spoke\nTimed the laugh, rehearsed the careful joke\nThe ceiling of a room I rented cheap\nStill knows the shape I held to fall asleep\nSomething in the jaw\nthe way it locks at \"fine\"\nyears of holding tension on that line\nI am fluent in the language of the trained\nbut my native tongue has no name\n\n[pre-chorus]\n(Vocal-Perf: Same as before, but with quiet, layered ad-lib harmonies.)\n(Inst: Same as first pre-chorus, but an added shaker loop builds energy.)\n(Chords: Em - C - G - D)\nThe posture that I practiced in the hall\nThe version of my voice I gave to all\nA frequency I tuned myself to hold\nTill I forgot the sound before the mold\n\n[chorus]\n(Mix: Added background vocal textures to increase energy.)\n(Inst: Same as first chorus, but the distant piano melody from the verse is layered in.)\n(Vocal-Perf: Same as first chorus.)\n(Chords: Em - C - G - D)\n(Hook-DNA: Identical to the first chorus.)\n(Melody-Harmonic-Tension: Identical to the first chorus.)\nStretching\n\n[bridge]\n(Mix: Stripped back. Beat drops out for the first half, leaving just pads and vocals.)\n(Vocal-Perf: More emotional and slightly higher in register; increased vulnerability.)\n(Inst: Filtered synth pad and piano only. Beat re-enters in the second half.)\n(Chords: C - G - D - Em)\n(Melody-Harmonic-Tension: Melody deliberately avoids the root note, hovering around the 5th and 7th, creating a feeling of being suspended and unresolved.)\nThere is a version of me that never learned to bend\nShe is somewhere past the places I have been\n\n[outro]\n(Mix: Begins to fade. A low-pass filter is applied to the whole mix, making it sound distant.)\n(Inst: Vocal chop melody from the chorus repeats and becomes more fragmented. Beat deconstructs.)\n(Vocal-Perf: Main vocal line repeats quietly, like a fading thought.)\n(Chords: Em - C)\nThe posture that I practiced in the hall\nStretching\nThe posture that I practiced in the hall",
  "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：深暗的蓝灰与消退的玫瑰粉之间的渐变层叠，像一层薄薄的皮肤被缓慢撕开，露出底层更冷的颜色——整体传递出一种精疲力竭的自我拉伸感，颜色之间的边界模糊却带有不均匀的张力痕迹。\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。",
