  "prompt": "Genre: Pop R&B with Trap undertones; BPM: 100; Key: D major; Rhythm: Relaxed mid-tempo trap groove with syncopated 808 kick/bass pocket, a prominent clap on beats 2 & 4, and fast 16th-note hi-hat rolls.; Instruments: Programmed 808 kit, deep gliding sine bass, warm detuned e-piano, shimmering ambient pad, muted synth plucks; Vocals: Male and Female duet. Male lead is a breathy, melismatic R&B tenor. Female lead is an intimate, rhythmic soprano. Both feature stylistic autotune and lush background vocal stacks.; Mood: The quiet hum of a city at 3 AM, seen through a high-rise window, with the warm glow of a single lamp inside.; Highlight: The sudden textural shift when the higher, rhythmically precise female vocal enters after the smooth, flowing male chorus, creating an immediate and refreshing dynamic contrast.",
  "title": "烟感",
  "lyrics": "[chorus]\nHook-DNA: Rhythmic pattern is four repeating eighth notes on beats 1-2; Pitch anchors on the 3rd of the tonic chord (F#); Motif repeats 4x with slight variation before resolving down.\nMelody-Contour: Gentle descending stepwise motion from 5th to 3rd, creating a soothing, simple arch.\nMelody-Rhythm: Vocal phrase starts directly on beat 1 with a consistent eighth-note flow, creating an infectious pop earworm.\nMelody-Harmonic-Tension: Melody is highly consonant, with gentle tension created when the melody's F# becomes the sweet major 7th over the Gmaj7 (IV) chord.\nVocal-Perf: Male lead, breathy and close-mic'd, soft delivery, almost a whisper.\nInst: Warm e-piano chords, deep 808 bass pulse, sparse trap hi-hats, distant ambient pad.\nChords: (Gmaj7 - A - Dmaj7 - Bm)\nMix: Vocal front and center with light saturation. Wide stereo field. Sub-bass prominent but clean. Crisp highs on hats. Main reverb is a medium plate, side-chained to the vocal.\n你外套上还留着我的烟感\n混进洗衣粉里散不干净\n那件旧毛衣袖口磨了边\n我舍不得洗，怕连气味都清零\n\n[verse]\nMelody-Contour: More conversational, smaller melodic range, staying on a few key notes.\nMelody-Rhythm: Syncopated, speech-like rhythm that plays against the steady beat, phrases starting after the downbeat.\nVocal-Perf: Male lead, slightly more assertive delivery than chorus, rhythmic and confident.\nInst: Kick drum pattern becomes more active, hi-hats introduce faster rolls, e-piano is more rhythmic.\nChords: (Gmaj7 - A - Dmaj7 - Bm)\nMix: Stereo field slightly narrower than chorus to build dynamic contrast.\n搬走的那天你拎了三个袋\n落下一双拖鞋在我浴室外\n我装作没看见，推到柜子背面\n偶尔洗澡看见，假装不在意\n冰箱里还有你买的苏打水\n喝掉一瓶又新开一瓶撑着\n好像这样就能留住什么\n其实不过是舍不得倒掉而已\n\n[verse]\nMelody-Contour: Ascending line in the first two phrases, creating a sense of questioning or urgency.\nMelody-Rhythm: Highly syncopated, percussive delivery with precise staccato notes and rests.\nVocal-Perf: Female lead enters. Timbre is brighter, breathier, and more rhythmically sharp than male lead.\nInst: Beat remains consistent, allowing the vocal change to be the main focus.\nChords: (Gmaj7 - A - Dmaj7 - Bm)\n我删了你又存回来两次\n备注改了又改，最后空着\n手机壳换了新的，贴膜也换了\n只是那条短信草稿还没发出去\n你说过喜欢我煮的汤\n现在汤锅搁在架子上落灰\n有时候路过厨房停一下\n终究还是关了灯走开\n\n[bridge]\nMelody-Harmonic-Tension: Phrases consistently end on the 2nd or 4th over the dominant (A) chord, creating unresolved tension that pulls strongly toward the final chorus.\nMelody-Contour: Ascending melody builds energy, peaking on the final line before dropping back into the chorus.\nVocal-Perf: Female lead, dynamics swell from intimate to more powerful, harmonies are introduced.\nInst: A low-pass filter sweeps open on the pad, hi-hats become more frantic, subtle riser SFX builds in the background.\nChords: (Gmaj7 - Gmaj7 - A - A)\n不是没想过彻底整理一遍\n把所有边角都清扫干净\n可手伸进柜子摸到那双拖鞋\n又缩回来，深呼吸，没动它\n我知道这不叫放不下\n只是习惯了有你气味的空气\n\n[chorus]\nHook-DNA: Rhythmic pattern is four repeating eighth notes on beats 1-2; Pitch anchors on the 3rd of the tonic chord (F#); Motif repeats 4x with slight variation before resolving down.\nMelody-Harmonic-Tension: Consonant melody, but the emotional weight is increased by the dense vocal layers.\nVocal-Perf: Male and Female duet. Lush background vocal stacks enter, singing harmonies and counter-melodies.\nInst: Full instrumentation, drums hit harder, an additional arpeggiated synth layer is added for energy.\nChords: (Gmaj7 - A - Dmaj7 - Bm)\nMix: Widest and loudest point of the song. Parallel compression on the master bus for punch. Vocal ad-libs are panned hard left and right.\n你外套上还留着我的烟感\n混进洗衣粉里散不干净\n那件旧毛衣袖口磨了边\n我舍不得洗，怕连气味都清零\n苏打水还剩最后一瓶在冰箱\n我一直没去开它\n\n[outro]\nVocal-Perf: Male vocal ad-libs, fading out with heavy reverb and delay throws.\nInst: Instruments strip away one by one, leaving only the e-piano and a lingering pad.\nMix: Gradual fade-out, reverb tails become more prominent as dry signals disappear.\n那双拖鞋还在柜子背面放着\n我也不知道在等什么\n只是没动它\n就这样没动它",
