  "lyrics": "[intro]\n(Chords: Fm - C7 - Dbmaj7 - C7)\n(Inst: Nylon guitar plays a melancholic arpeggiated motif. Lo-fi hip-hop beat enters with vinyl crackle. Strings swell in.)\n(Mix: Intimate, narrow stereo field initially, widens with strings.)\n(Sound-Design: Atmospheric pad, distant wind sound.)\n\n[verse]\n(Chords: Fm - C7 - Dbmaj7 - C7)\n(Vocal-Perf: Rhythmic, almost spoken rap; steady, confident flow; mezzo-piano.)\n(Inst: The core loop of nylon guitar, bass, and drums. Strings hold long, subtle notes in the background.)\n(Melody-Rhythm: Conversational, syncopated against the beat.)\n(Transition: Subtle reverse cymbal swell.)\n一群嗜血的蚂蚁 被腐肉所吸引\n我面无表情 看孤独的风景\n失去你 爱恨开始分明\n失去你 还有什么事好关心\n当鸽子不再象征和平\n我终于被提醒\n广场上喂食的是秃鹰\n我用漂亮的押韵\n形容被掠夺一空的爱情\n\n[pre-chorus]\n(Chords: Bbm7 - Fm - C7 - Fm)\n(Vocal-Perf: Becomes more melodic and sung, a clear lift in energy and pitch, building tension.)\n(Inst: Strings become more prominent, playing a rising line. Beat becomes slightly more active with a light fill.)\n(Transition: A clean pause for a beat before the chorus hits.)\n啊 乌云开始遮蔽 夜色不干净\n公园里 葬礼的回音 在漫天飞行\n送你的白色玫瑰\n在纯黑的环境凋零\n乌鸦在树枝上诡异的很安静\n静静听 我黑色的大衣\n想温暖你日渐冰冷的回忆\n走过的走过的生命\n啊 四周弥漫雾气\n啊 我在空旷的墓地\n老去后还爱你\n\n[chorus]\n(Chords: Fm - C7 - Db - Ab - Bbm - Fm - C7 - Fm)\n(Vocal-Perf: Soft, breathy singing; smooth, connected phrases; emotional but restrained.)\n(Inst: Acoustic piano enters as the lead instrument, playing the iconic classical-inspired melody. Lush, wide strings provide a dramatic backdrop. The full hip-hop beat drives underneath.)\n(Mix: Maximum width and depth. Piano is bright and centered, strings fill the stereo field. Vocals sit comfortably in the middle.)\n为你弹奏肖邦的夜曲\n纪念我死去的爱情\n跟夜风一样的声音\n心碎的很好听\n手在键盘敲很轻\n我给的思念很小心\n你埋葬的地方叫幽冥\n\n[interlude]\n(Chords: Fm - C7 - Db - Ab - Bbm - Fm - C7 - Fm)\n(Inst: Nylon guitar plays an expressive, improvised solo over the chorus progression. Strings and piano provide harmonic support. Beat continues.)\n(Mix: Guitar is brought to the forefront, treated with a touch of reverb.)\n(Sound-Design: A subtle whoosh transitions out.)\n\n[verse]\n(Chords: Fm - C7 - Dbmaj7 - C7)\n(Vocal-Perf: Rap delivery returns, slightly more urgent and intense than the first verse.)\n(Inst: Back to the foundational loop of guitar, bass, and drums. Piano drops out.)\n(Melody-Rhythm: More complex syncopation in the rap flow.)\n那些断翅的蜻蜓 散落在这森林\n而我的眼睛 没有丝毫同情\n失去你 泪水混浊不清\n失去你 我连笑容都有阴影\n风在长满青苔的屋顶\n嘲笑我的伤心\n像一口没有水的枯井\n我用凄美的字型\n描绘后悔莫及的那爱情\n\n[chorus]\n(Chords: Fm - C7 - Db - Ab - Bbm - Fm - C7 - Fm)\n(Vocal-Perf: Sung with slightly more intensity and emotion, a few subtle ad-libs.)\n(Inst: Full instrumentation returns. Piano melody, lush strings, nylon guitar arpeggios, and the hip-hop beat all combine for the final climax.)\n(Mix: The fullest and most powerful section of the song.)\n为你弹奏肖邦的夜曲\n纪念我死去的爱情\n而我为你隐姓埋名\n在月光下弹琴\n对你心跳的感应\n还是如此温热亲近\n怀念你那鲜红的唇印\n\n[outro]\n(Chords: Fm - C7 - Dbmaj7 - C7)\n(Inst: The beat and bass fade out, leaving the nylon guitar loop and a final, lingering piano chord.
