  "prompt": "Genre: Hi-NRG / Trance; BPM: 127; Key: C Major; Rhythm: A propulsive, sequenced 16th-note analogue-style synth bassline locked to a hard-hitting four-on-the-floor modern techno kick, creating a relentless, hypnotic groove with off-beat open hi-hats.; Instruments: Sequenced synth bass; Layered supersaw pads; Fast trance arps; Hard techno kick; Layered digital snare; SFX risers/sweeps.; Vocals: Female, ethereal and breathy head voice, heavily processed with long delays, lush background vocal stacks, and spacious reverb, delivering repetitive, chant-like phrases that float above the mix.; Mood: The sensory overload of a laser-filled superclub at 3 AM, strobe lights fracturing time as you lose yourself completely in the hypnotic, driving pulse of the music.; Highlight: The split-second of near silence in the final riser of the breakdown, where only a high-pass filtered synth verb tail hangs in space before the kick drum slams back in with full sub-bass impact on the downbeat.",
  "title": "Weightless Ground",
  "lyrics": "[intro]\n(Mix: Hard-hitting, sub-heavy techno kick sidechaining all synth elements; ultra-wide stereo image with arpeggios panning; pristine highs, controlled mids; expensive analogue warmth across the master bus)\n(Inst: Sequenced 16th-note synth bass enters; layered with hard techno kick and offbeat open hi-hat; a high-pass filtered trance arp slowly opens up)\n(Sound-Design: White noise sweep riser builds to first verse)\n\n[verse]\n(Melody-Contour: Monotone chant on the root, a hypnotic plateau)\n(Melody-Rhythm: Phrases land on beat 1 of every 2 bars, long sustained notes)\n(Vocal-Perf: Ethereal, breathy head voice; processed with heavy reverb and stereo delay)\n(Inst: A shimmering trance pad is added behind the main arpeggio)\n(Chords: C - G - Bb - F)\nOoh... dissolve, dissolve, dissolve, dissolve, dissolve\n\n[pre-chorus]\n(Vocal-Perf: Intensity builds slightly, vocal becomes less breathy)\n(Inst: Snare drum with a large hall reverb enters, building anticipation)\n(Chords: C - G - Bb - F)\nOoh... pull me through, pull me through, pull me through, pull me through, pull me through\n\n[chorus]\n(Hook-DNA: Rhythmic motif is 'eighth-eighth-quarter' on \"I feel love\", landing on beat 1; melody anchored on the 5th (G) and 3rd (E); motif repeats 4 times, then a final tag resolves to the root (C))\n(Melody-Harmonic-Tension: The high sustained vocal on the 5th (G) over the bVII (Bb) and IV (F) chords creates a feeling of euphoric, floating suspension, resolving only when the harmony returns to the I (C) chord.)\n(Vocal-Perf: Vocal becomes clearer with multiple harmony layers added for a stacked effect)\n(Mix: Stereo field widens; sidechain compression becomes more pronounced)\n(Inst: A bright supersaw synth layer enters, playing the main chords)\n(Chords: C - G - Bb - F)\nOoh... weightless ground, weightless ground, weightless ground, weightless ground, weightless ground\nWeightless ground, weightless ground\n\n[interlude]\n(Mix: All low-end is high-pass filtered out; mix becomes cavernous with huge reverb tails)\n(Inst: Kick and bass drop out, leaving only the filtered trance arpeggio and shimmering pads; a simple, melodic synth lead enters)\n(Sound-Design: A long white noise riser builds tension for the next section)\n\n[verse]\n(Melody-Contour: Returns to the single-note chant, maintaining the hypnotic feel)\n(Melody-Rhythm: Same phrasing as first verse, locking into the re-established groove)\n(Vocal-Perf: Breathy delivery returns, with a subtle harmony layer underneath)\n(Inst: The full kick and bass slam back in; a new counter-melody arp is introduced)\n(Chords: C - G - Bb - F)\nOoh... let it rise, let it rise, let it rise, let it rise, let it rise\n\n[pre-chorus]\n(Vocal-Perf: Builds intensity again, harmonies become more prominent)\n(Inst: Snare hits become more frequent, often with a driving 16th-note fill)\n(Chords: C - G - Bb - F)\nOoh... past the sky, past the sky, past the sky, past the sky, past the sky\n\n[chorus]\n(Hook-DNA: Rhythmic motif is 'eighth-eighth-quarter' on \"I feel love\", landing on beat 1; melody anchored on the 5th (G) and 3rd (E); motif repeats 4 times, then a final tag resolves to the root (C))\n(Melody-Harmonic-Tension: The high sustained vocal on the 5th (G) over the bVII (Bb) and IV (F) chords creates a feeling of euphoric, floating suspension, resolving only when the harmony returns to the I (C) chord.)\n(Vocal-Perf: Fullest vocal stacks of the song; ad-libs with heavy delay are added in the gaps)\n(Mix: Maximum width and dynamic impact)\n(Inst: All synth layers are playing; snare drum has a bigger reverb, creating a huge feel)\n(Chords: C - G - Bb - F)\nOoh... weightless ground, weightless ground, weightless ground, weightless ground, weightless ground\nWeightless ground, weightless ground, weightless ground, weightless ground\n\n[outro]\n(Melody-Harmonic-Tension: Melody alternates between the root (C) and the minor 7th (Bb), creating a new, insistent tension over the static C chord before the fade)\n(Mix: High-pass filter is slowly applied to the entire track, removing low-end)\n(Vocal-Perf: Main vocal fades out, leaving only the delayed ad-libs repeating and echoing into silence)\n(Inst: Instruments drop out one by one, leaving only the bass sequence and a single pad, which then fades)\n(Chords: C - G - Bb - F)\nOoh... further in, further in, further in, further in, further in\nOoh... past the skin, past the skin, past the skin, past the skin, past the skin\nOoh... weightless ground, weightless ground, weightless ground, weightless ground, weightless ground\nWeightless ground, weightless ground, weightless ground, weightless ground, weightless ground, weightless ground",
  "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：深空蓝与冷白之间的极度渐变，像高压电弧在黑暗中瞬间打开又消失，中部有一层几近透明的冰蓝色薄雾横贯画面，边缘向暗紫沉降，整体传达出失重感与身体边界溶解的瞬间。\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。",
