  "prompt": "Genre: J-Pop / Orchestral Ballad; BPM: 162; Key: E Major; Rhythm: Driving ballad groove with a steady backbeat and constant, propulsive 16th-note hi-hats. Syncopated piano chords add rhythmic interest.; Instruments: Bright grand piano (arpeggios/chords), lush string section (soaring lines), clean electric bass, live acoustic drums (crisp snare), subtle clean electric guitar textures.; Vocals: Female, clear and emotive with a bright timbre. Dynamic range from soft, breathy verses to a powerful, controlled belt in the chorus. Light, airy head voice used for effect.; Mood: Walking home alone in a downpour, city lights blurring through the rain on your eyelashes, clutching a jacket where an umbrella used to be.; Highlight: The moment the full string section and crash cymbals enter on the downbeat of the first chorus, immediately elevating the emotional scale from personal regret to epic heartbreak.",

  "lyrics": "[intro]\n(Chords: E - B/D# - C#m7 - A)\n(Inst: Bright grand piano plays a delicate, descending arpeggio motif, mimicking raindrops. A soft pad of high strings enters, creating a melancholic atmosphere.)\n(Mix: Intimate, piano centered, preparing for vocal entry.)\n(Sound-Design: A subtle whoosh with reverse cymbal leading into the verse.)\n\n[verse]\n(Chords: E - B/D# - C#m7 - A - E - B/D# - C#m7 - A)\n(Vocal-Perf: Gentle, breathy chest voice, mezzo-piano dynamic, sense of quiet reminiscing.)\n(Inst: Piano continues arpeggios, clean bass enters on root notes. Drums enter with a simple kick and closed 16th-note hi-hat pattern, no snare yet.)\n(Melody-Contour: Mostly stepwise motion with small melodic leaps, conversational rhythm.)\n放学路上的那个转角\n你总爱把书包挂在我肩膀\n制服袖口磨出了细细的线头\n我一直没舍得剪掉\n\n[pre-chorus]\n(Chords: A - E/G# - F#m7 - Bsus4 - B)\n(Vocal-Perf: Intensity builds slightly, moving from storytelling to direct questioning. Clearer, more forward tone.)\n(Inst: Snare drum enters with a steady backbeat. String section swells in volume, building tension towards the chorus.)\n(Mix: Vocals become more present. Stereo field widens with the strings.)\n(Transition: A clean, powerful drum fill leads directly into the chorus downbeat.)\n那些夏天 教室里飘来饭菜香\n你偷偷传来折成飞机的便条纸\n我以为 以为这些\n就能一直一直下去\n\n[chorus]\n(Chords: E - B - C#m7 - A - E - B - C#m7 - A)\n(Vocal-Perf: Strong, emotive, full-voiced delivery at mezzo-forte. Soaring melody in a higher register.)\n(Inst: Full band enters with power. Driving 16th-note hi-hats, powerful snare on 2 & 4. Piano plays strong block chords. Strings play a high, soaring counter-melody.)\n(Mix: Wide, epic soundscape. Vocals sit powerfully on top of the dense arrangement.)\n时间它走得太快 快过我的心跳\n那段走廊 那些课间的回响\n我们都以为长大以后还会相遇\n却在某个早晨 悄悄变成了陌生人的方向\n\n[verse]\n(Chords: E - B/D# - C#m7 - A - E - B/D# - C#m7 - A)\n(Vocal-Perf: Returns to a softer, more narrative tone, but with more underlying emotion than the first verse.)\n(Inst: The energy pulls back slightly, but the full drum groove continues. A clean electric guitar plays subtle arpeggiated figures, adding texture.)\n(Melody-Dev: Similar contour to the first verse but with slight rhythmic variations.)\n毕业照压在抽屉最深处\n你侧脸的角度我还记得\n只是再翻出来\n已经叫不出你现在住哪个城市\n\n[bridge]\n(Chords: C#m7 - B - A - E/G# - F#m7 - G#m7 - A - Bsus4 - B)\n(Vocal-Perf: Starts intimately, almost spoken, then builds to a desperate, high-note plea.)\n(Inst: Dynamics drop initially to just piano and vocals. Strings re-enter and build in a dramatic crescendo. Drums build with cymbal swells and tom fills.)\n(Mix: Dynamic shift from narrow and dry to wide and wet, mirroring the emotional build.)\n(Transition: Vocal holds a high, emotional note over a suspended chord before resolving into the final chorus.)\n如果当初我没有沉默\n如果那天我追出了校门口\n是不是现在 拨出去的号码\n还有人接\n还不会是空号\n\n[chorus]\n(Chords: F# - C# - D#m7 - B - F# - C# - D#m7 - B)\n(Vocal-Perf: Most powerful and emotional delivery. High-register ad-libs are layered over the main vocal.)\n(Structure: Key change up a whole step to F# major for climactic lift.)\n(Inst: Cymbals are crashing more frequently. Strings are at their most prominent, playing dramatic, fast-paced lines. The entire band is playing at peak energy.)\n(Mix: The biggest, widest point of the song. Saturated with emotion and sound.)\n时间它走得太快 快过我的心跳\n那段走廊 那些课间的回响\n我们都以为长大以后还会相遇\n却在某个早晨 悄悄变成了陌生人的方向\n\n[outro]\n(Chords: E - B/D# - C#m7 - A - E)\n(Vocal-Perf: Soft, resigned, and breathy. Fades out with a final delicate phrase.)\n(Structure: Returns to the original key of E major.)\n(Inst: The arrangement deconstructs, leaving only the initial piano arpeggio motif and fading strings. The final chord rings out.)\n(Mix: A long reverb tail on the final vocal note and piano chord, fading to silence.)\n袖口的线头 我终究还是剪掉了\n你的名字 也只剩这一件旧衣裳",
