  "prompt": "Genre: Ambient Pop / Alternative R&B; BPM: 62; Key: C Major (with modal ambiguity); Rhythm: Extremely loose, unquantized feel, driven by arpeggiated guitar and washy synth pads, no percussive grid; Instruments: Close-mic'd electric guitar arpeggios, warm analog synth pads, deep sub-bass synth, raw acoustic guitar, processed vocal textures; Vocals: Male, intimate and gentle lead vocal often in falsetto, contrasted with a heavily processed, high-pitched, autotuned vocal alter-ego; lush background vocal stacks; Mood: The quiet hum of a car engine on a long, dark highway after a breakup, streetlights blurring through a rain-streaked windshield; Highlight: The abrupt transition where the organic, close-mic'd lead vocal is completely replaced by a high-pitched, heavily autotuned vocal stack, shifting from personal memory to a surreal, disembodied reflection.",
  "title": "Hollow Season",
  "lyrics": "[verse]\n(Melody-Contour: Conversational, mostly stepwise motion within a narrow range, occasional gentle leap up a 4th, descending tail on phrases.)\n(Melody-Rhythm: Phrasing starts just after the beat, very legato, floating over the arpeggios, not locked to a grid.)\n(Vocal-Perf: Intimate, close-mic'd, breathy tone, bordering on whisper. Gentle, understated delivery.)\n(Inst: Electric guitar arpeggio continues as main support. Synth pad swells become more prominent.)\n(Chords: Cmaj7 - G - Am7 - Fmaj7)\nGrocery list still on the fridge\nYour handwriting, those loops and sticks\n\n[chorus]\n(Hook-DNA: Core motif is a two-note descending phrase on the title words; Rhythm is long, held notes; Repeats with slight variation, anchoring on the tonic.)\n(Melody-Contour: Lifts into a higher register, gentle arch shape, peak on a perfect 5th, resolves downwards.)\n(Melody-Rhythm: Sustained notes, contrasting with the more rhythmic verse. Phrases land squarely on downbeats.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the tonic chord for a full bar, creating a dreamy, unresolved feeling before descending.)\n(Vocal-Perf: Slightly more projection than verse, introduction of soft falsetto and subtle vocal layers panned wide.)\n(Inst: Synth pad becomes the dominant harmonic element, guitar softens.)\n(Chords: Fmaj7 - Cmaj7 - G - Am7)\nHollow season settling in\nSoft and slow\n\n[verse]\n(Vocal-Perf: Returns to the intimate, breathy delivery. A second, quiet harmony vocal is introduced, panned left.)\n(Melody-Contour: Similar contour to first verse, but with more descending phrases, creating a sense of finality.)\n(Melody-Rhythm: Slightly more syncopated phrasing, weaving around the guitar arpeggio.)\n(Inst: Guitar remains central. A very low, subtle sub-bass synth pulse enters.)\n(Chords: Cmaj7 - G - Am7 - Fmaj7)\nThere's a drawer I never open now\nFull of things we both forgot somehow\nA dead houseplant\nAnd a version of me you knew\n\n[chorus]\n(Hook-DNA: Repeats the descending title motif; Rhythm is again sustained; Now includes the 'Good times' tag, a simple descending 3-note melody that resolves to the tonic.)\n(Melody-Contour: Same arch shape, but the phrase extends with a descending tail.)\n(Melody-Rhythm: Held notes on the main phrase, followed by a short, rhythmically simple tag.)\n(Melody-Harmonic-Tension: Tension on the major 7th is repeated, but resolved more quickly by the 'Good times' tag landing on the root.)\n(Vocal-Perf: More layers added, creating a thicker, more lush vocal stack. Lead vocal in a clear, gentle falsetto.)\n(Inst: Synth pads swell to their fullest. Guitar becomes a textural element.)\n(Chords: Fmaj7 - Cmaj7 - G - Cmaj7)\nHollow season\nStill, I grow\n\n[bridge]\n(Melody-Harmonic-Tension: The melody consistently lands on the 2nd and 4th over the chords, creating a sustained, gentle dissonance that feels questioning and doesn't resolve until the final line.)\n(Vocal-Perf: Most emotionally direct and clear vocal delivery. Less breathy, more pure tone. Stacked harmonies are precise and choir-like.)\n(Inst: Instrumentation strips back slightly. A new, brighter synth pad enters. Raw, strummed acoustic guitar faintly in the background.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nThe voicemail I saved just to hear you breathe\nTwenty-three seconds, a Wednesday in March\nI've mapped every silence between the words\nUntil the hollow season thins and thaws\n\n[interlude]\n(Sound-Design: Abrupt hard cut into the new texture.)\n(Vocal-Perf: Multiple layers of heavily autotuned and pitch-shifted vocals, creating a robotic, choral effect. No clear lead.)\n(Inst: All previous instruments drop out. Replaced by a synthesized, vocoded choir built from vocal samples.)\n(Mix: Stereo image becomes extremely wide and disorienting. Heavy use of chorus, flanger, and delay effects.)\n(Chords: Am - G/B - C - F)\nAll we leave, leave\nAll we leave, leave\n\n[outro]\n(Transition: Vocoder choir fades into a single, high-pitched processed vocal.)\n(Vocal-Perf: A single, heavily processed vocal line. High-pitched, synthetic timbre, almost like a synth lead. Delivers a spoken-word-like, philosophical monologue.)\n(Melody-Contour: Monotonic delivery with slight pitch variations, more rhythmic than melodic. No clear contour.)\n(Melody-Rhythm: Rhythm is speech-like, fluid and non-metrical.)\n(Inst: Minimal ambient synth drone in the background. The processed voice is the primary focus.)\n(Mix: Mix becomes very dry and centered, focusing all attention on the processed vocal. All previous reverb and space is removed.)\n(Chords: Static Fmaj7 drone)\nMaybe the self you grieve was always borrowed\nA coat you wore because the air felt cold\nAnd everything you held so close in sorrow\nWas just the shape of something yet untold\nThe drawer stays shut but the room still breathes\nYou're not behind, you're not a broken thing\nSomething beneath the quiet hum persists\nUnnamed, unfinished\nStill insisting it exists",
  "cover_prompt": "生成一张极简主义的几何光影艺术图片作为无字音乐专辑封面。画面的核心是：一个边缘极度柔和、几乎溶入背景的半透明椭圆形光晕，悬浮于从深冬灰蓝渐变至温暖灰褐色的水彩背景之中，光晕内部有一丝极淡的、接近消失的米白色，如同空置房间里扩散的最后一缕暖气。画面必须展现出微妙的高级材质肌理，特别是类似水彩晕染（Watercolor texture）或粗糙艺术纸张的触感。整体构图极度克制、留白（Minimalistic composition），注重光与影的柔和交错（Light and shadow interplay）。强烈要求：画面必须保持极致的安宁与静谧（Calm and serene），除了基础的、柔焦的简单几何图形（如模糊的圆、半透明的方块或柔和的线条）外，绝对不要出现任何复杂的现实物体、风景或人物！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母！绝对不要生成人物轮廓。传达出一种充满诗意、呼吸感与冥想空间的视觉感受。",
