  "prompt": "Genre: Latin Jazz-Funk Fusion; BPM: 115; Key: C Major / A minor; Rhythm: driving pocket syncopation with a relaxed, back-beat feel driven by the tight interplay of fretless bass and congas, creating a constant forward motion; Instruments: Closely-mic'd nylon guitar with audible finger noise, clean semi-hollow electric guitar, warm fretless bass, dry congas/bongos, subtle drum kit with shakers and rim clicks; Vocals: Instrumental; Mood: Sipping a cool drink on a terracotta patio at dusk, the last of the day's heat radiating from the stones; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Dynamic and clean, with a wide stereo image for percussion and a solid, centered bass anchor; Structure: Intro; Verse; Chorus; Interlude; Chorus; Outro; Highlight: The sudden, fiery burst of a rapid, bluesy electric guitar run that enters immediately after a lyrical, laid-back nylon string guitar solo, jolting the energy upward.",

  "lyrics": "[intro]\n(Mix: Warm, spacious, and dynamic. Bass and kick centered. Percussion and rhythmic guitar panned wide L/R. Clean separation with minimal compression, preserving transients. A touch of plate reverb gives a sense of a live room.)\n(Inst: Nylon-string acoustic guitar, fretless electric bass, congas, shaker)\n(Chords: Am7 - Dm7 - G7 - Cmaj7)\n\n[verse]\n(Hook-DNA: Syncopated motif starts on upbeat of 4, arpeggiates down the minor chord, anchoring on the 5th; Repeats twice, third time resolves to the relative major tonic.)\n(Melody-Contour: Descending arpeggios followed by a stepwise ascending line to the major third, creating an arch shape over two bars.)\n(Melody-Rhythm: Phrases are built on sixteenth-note runs that resolve into longer held notes, creating a push-and-pull against the steady percussion.)\n(Inst: Lead nylon guitar carries melody, fretless bass plays counter-melody, percussion remains constant.)\n(Chords: Am7 - Dm7 - G7 - Cmaj7 - Fmaj7 - E7alt)\n赤陶砖缝里白昼藏的那口气\n悄悄从地面往腿骨方向爬\n你坐在我斜对面三十公分处\n冰杯外壁的水珠停在你指根\n我们对视了一下\n又各自别开\n那句话撑在喉腔\n像石头压着石头\n\n[chorus]\n(Hook-DNA: A more declarative quarter-note based motif, lands squarely on beat 1, circles the root and third; Repeats once, then a call-and-response phrase with a clean electric guitar fill.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the tonic chord for a full beat, creating a bright, lingering tension before resolving down.)\n(Vocal-Perf: Lead guitar plays with more confidence and sustain, less intricate but more powerful.)\n(Inst: Clean electric guitar enters with subtle chordal fills and response lines.)\n(Mix: Stereo image widens slightly as electric guitar is added opposite the nylon string.)\n(Chords: Fmaj7 - G7 - Cmaj7 - Am7 - Dm7 - E7 - Am7)\n烫过石头的手摸过你\n那个烫不是太阳给的\n是我压了整个傍晚的那团燃\n终于从掌心往外决了堤\n我们坐在同一块余温里\n却没有一个字落了地\n\n[interlude]\n(Vocal-Perf: An improvised, virtuosic solo on the clean electric guitar, characterized by fast pentatonic runs, string bends, and blues-inflected phrasing.)\n(Melody-Harmonic-Tension: Solo creates tension by using chromatic passing tones and rapid flurries of notes against the slower-moving chord changes, frequently resolving phrases on the 9th or 13th of the chord.)\n(Inst: Electric guitar takes focus, backed by bass, congas, and shaker. Nylon guitar drops out.)\n(Mix: Solo guitar is pushed to the front with a dedicated, slightly longer reverb and a subtle slapback delay.)\n(Chords: Am7 - Dm7 - G7 - Cmaj7 - Fmaj7 - E7alt)\n\n[chorus]\n(Hook-DNA: Main declarative motif returns, but now the nylon and electric guitars play it in harmony or in tight call-and-response.)\n(Melody-Harmonic-Tension: The major 7th tension is heightened by the dual-guitar texture, with one guitar holding the note while the other plays a harmony a third below.)\n(Vocal-Perf: Both guitars play with maximum energy, a final statement of the theme.)\n(Inst: Full ensemble, heightened rhythmic intensity from the congas.)\n(Mix: The loudest and widest point of the track. Light bus compression glues the elements together.)\n(Chords: Fmaj7 - G7 - Cmaj7 - Am7 - Dm7 - E7 - Am7)\n远处铁架子一声脆响\n穿进来又立刻被庭院吞掉\n你抬了一下眼皮\n我张开嘴\n又闭上\n烫过石头的手摸过你\n那个烫不是太阳给的\n是我压了整个傍晚的那团燃\n终于从掌心往外决了堤\n\n[outro]\n(Inst: Electric guitar holds a final, feedback-tinged note. Bass and congas continue the main groove, slowly fading out over several bars.)\n(Mix: A long, slow fade. Reverb tails become more prominent as the direct signal level drops.)\n(Chords: Vamping on Am7)\n热气还在往上走\n那句话还压在石头下面",
  "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：黄昏时分赤陶砖地面蓄积的热量向上蒸腾的视觉感——最底层是沉砖红与烧土橙的浓郁色层，中间过渡为模糊的琥珀黄，最上层化入一片灰蓝的暮色，整体像热气正在穿越色彩边界向上爬行，压抑而炙烫。\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。",
