  "prompt": "Genre: Indie Folk / Chamber Pop; BPM: 108; Key: G Major; Rhythm: Intricate, interlocking fingerstyle acoustic guitar arpeggios in 4/4, creating a continuous, flowing polyrhythmic texture without percussion; Instruments: Two close-miked steel-string acoustic guitars (L/R panned, audible finger/fret noise), mandolin-style plucks (bright, high-end shimmer), distant upright piano (warm chordal padding); Vocals: Male, intimate close-mic, high tenor/falsetto, breathy and delicate delivery, with lush, multi-tracked background vocal stacks creating a choral effect; Mood: The quiet light of late afternoon filtering through a dusty window, illuminating floating dust motes as a conversation from the next room fades; Highlight: the moment the multi-tracked background vocal choir enters on the final phrase of the first chorus, blooming from a solo voice into a wide, ethereal pad",

  "lyrics": "[intro]\n(Inst: Two close-miked acoustic guitars, panned L/R. Finger noise and string resonance audible. One plays bass notes/chords, other plays intricate arpeggiated melody.)\n(Mix: Wide stereo image, natural small-room reverb, transparent master bus compression. Warm low-mids, clear but gentle high-end. Intimate and centered vocal space established.)\n(Chords: G - D/F# - Em7 - C)\n\n[verse]\n(Vocal-Perf: Breathy, delicate high-tenor, almost whispered. Close-mic intimacy, minimal processing.)\n(Melody-Rhythm: Vocal phrases begin just after the downbeat, floating gently over the continuous guitar rhythm.)\n(Melody-Contour: Primarily stepwise, gentle arching shape within a narrow range.)\n(Inst: Interlocking acoustic guitars continue as the main harmonic and rhythmic bed.)\n(Chords: G - D/F# - Em7 - C - G)\n你贴在冰箱门上那张黄色的纸\n边角卷起来了 字迹已经淡去\n我没有撕掉它 只是绕着它走\n假装还有人等我回家吃饭喝粥\n\n[chorus]\n(Vocal-Perf: Lead vocal remains soft, joined by lush multi-tracked harmonies that swell in dynamics, creating a choral texture.)\n(Hook-DNA: Descending 3-note melodic motif on \"woe-oh-woah\" (scale degrees 5-4-3), syncopated eighth-note rhythm, resolves on final phrase \"mystery of love\" which anchors on the tonic.)\n(Melody-Harmonic-Tension: Vocal harmonies create brief, poignant suspensions against the root chords, resolving on the last beat of the bar, especially on the word \"cease\".)\n(Inst: Bright mandolin-style arpeggios enter, layering on top of guitars. Distant piano adds subtle chordal wash.)\n(Mix: Stereo image widens significantly as harmonies enter.)\n(Chords: C - G - D - Em - C - G - D)\n那些话说不出口\n只剩下 纸上的温柔\n风吹过 窗缝轻抖\n我还在 这里等候\n\n[interlude]\n(Inst: Instrumental focus. Guitars, mandolin, and piano interweave complex counter-melodies. Wordless vocal harmonies float in the background like a pad.)\n(Chords: G - D/F# - Em7 - C)\n\n[verse]\n(Vocal-Perf: Delivery gains a subtle increase in emotional weight compared to first verse.)\n(Inst: Arrangement is slightly denser, with mandolin fills continuing subtly from the chorus.)\n(Chords: G - D/F# - Em7 - C - G)\n你走的那个早晨 锅里的水还开着\n我关了火 听见走廊里脚步声消散\n手机震了一下 是快递的消息\n那是你走前帮我订的 两人份的米\n\n[chorus]\n(Vocal-Perf: Harmonies are more prominent from the start of the section. Lead vocal has a stronger, more yearning quality.)\n(Hook-DNA: Same core melodic/rhythmic motif, but the final phrase's delivery is more pleading.)\n(Melody-Harmonic-Tension: Dissonance in harmonies is held slightly longer, increasing the emotional pull before resolution.)\n(Inst: All instrumental layers are present and active, creating the fullest texture yet.)\n(Chords: C - G - D - Em - C - G - D)\n那些话说不出口\n只剩下 纸上的温柔\n风吹过 窗缝轻抖\n我还在 这里等候\n\n[bridge]\n(Vocal-Perf: Reaches dynamic peak. Notes are more sustained, moving into a fuller, though still airy, head voice.)\n(Melody-Harmonic-Tension: Melodic phrases deliberately end on unstable scale degrees (2nd or 4th) over the chords, withholding resolution to build a sense of questioning and longing.)\n(Inst: Instruments shift from arpeggios to more sustained, simple chords, creating space and highlighting the vocal tension.)\n(Chords: Am - G/B - C - G - D - G)\n如果我把那张纸揭下来\n是不是就承认你不回来\n它的背面写了什么我没看\n也许是"盐不多了"\n也许什么都没有\n只是一张空白\n\n[outro]\n(Vocal-Perf: Fades out on layered, ethereal harmonies repeating the main hook motif without lyrics.)\n(Inst: Instruments slowly strip away, leaving just a final, sparse guitar arpeggio and the reverb tail of the vocal harmonies.)\n(Mix: Gradual volume fade. Reverb becomes more prominent as dry signals disappear.)\n(Chords: C - G - D - Em - C - G - D - G)\n那些话说不出口\n只剩下 纸上的温柔\n风吹过 窗缝轻抖\n我还在 这里等候\n",
