  "lyrics": "[intro]\n(Chords: Bm - F#m/A - G - D/F# - Em7 - A - D - D)\n(Inst: Guzheng plays the main melodic motif, supported by lush string pads, gentle piano arpeggios, and a sparse, atmospheric beat. Xiao flute adds breathy textures.)\n(Mix: Wide and cinematic, establishing the nostalgic mood.)\n\n(Transition: String swell and a single Guzheng pluck leads into the verse.)\n[verse]\n(Chords: Bm - F#m/A - G - D/F# - Em7 - A - D - D)\n(Vocal-Perf: Gentle, conversational, mezzo-piano, clear R&B-influenced enunciation.)\n(Inst: Piano and clean electric bass form the core harmony. The drum beat is simple and steady. Guzheng provides delicate fills between vocal phrases.)\n(Mix: Vocals are intimate and upfront. Instruments create a spacious backdrop.)\n旧日历翻到那一页折了角\n外婆缝的布鞋鞋底磨薄了\n院子里的枇杷树挂着未熟的果\n信封里的字迹被晒淡了颜色\n\n(Transition: Strings subtly swell to lift the energy.)\n[pre-chorus]\n(Chords: Bm - F#m/A - G - D/F# - Em7 - A - D - A)\n(Vocal-Perf: Intensity builds slightly, leading into the chorus. Melody ascends.)\n(Inst: String section becomes more prominent, adding emotional weight. The final 'A' chord creates harmonic tension.)\n候鸟年年飞过南山的那道弯\n它不知道有人在山脚盼天暖\n而等待是一根针\n扎进了最软的心间\n\n(Transition: A clean drum fill and a cymbal crash.)\n[chorus]\n(Chords: Bm - Em - A - D - G - D/F# - Em - A)\n(Vocal-Perf: Mezzo-forte, more open and emotive tone, sustained notes with subtle R&B runs.)\n(Inst: The full arrangement is present. Guzheng plays a driving arpeggio pattern that interweaves with the vocal melody. Strings are lush and soaring.)\n(Mix: The soundscape opens up, becoming wider and more dynamic.)\n风筝线断了才知道线有多长\n这条路走散了才知道你在哪方\n我把思念折成纸船放进河塘\n它漂向你还是漂向了远方\n\n(Transition: Strings hold a long note, then the arrangement strips back down.)\n[verse]\n(Chords: Bm - F#m/A - G - D/F# - Em7 - A - D - D)\n(Vocal-Perf: Returns to a softer, more narrative delivery. A sense of intimacy is re-established.)\n(Inst: The drum pattern becomes slightly more active with subtle hi-hats. Acoustic guitar is faintly layered, adding texture.)\n旧屋檐下的铃铛锈住了舌头\n不再叮当只剩风穿过的颤抖\n你走后我才学会辨认候鸟的叫声\n把每一声都当作你捎来的问候\n\n(Transition: A subtle reverse cymbal effect builds anticipation.)\n[pre-chorus]\n(Chords: Bm - F#m/A - G - D/F# - Em7 - A - D - A)\n(Vocal-Perf: Similar build to the first pre-chorus, but with slightly more urgency.)\n(Inst: Strings and Guzheng play with more intensity, leading powerfully into the final chorus.)\n那些没说完的话压在枕头下\n在无数个清晨\n随着晨雾一起蒸发\n\n(Transition: Full band hits together on the downbeat.)\n[chorus]\n(Chords: Bm - Em - A - D - G - D/F# - Em - A)\n(Vocal-Perf: Peak emotional delivery. Ad-libs and subtle vocal harmonies can be layered in the background. The final line is delivered with a touch of soft falsetto.)\n(Inst: All instrumental layers at their fullest. The string arrangement is at its most complex and cinematic.)\n(Mix: Maximum width and dynamic range. A final, powerful emotional climax.)\n风筝线断了才知道线有多长\n这条路走散了才知道你在哪方\n我把思念折成纸船放进河塘\n它漂到你手心 又怎样\n\n(Transition: The final chord rings out and instruments begin to fade.)\n[outro]\n(Chords: Bm - F#m/A - G - A - D)\n(Inst: The drum beat drops out, leaving the Guzheng and Xiao flute to trade final melodic phrases over fading piano chords and string pads.)\n(Structure: Instruments fade out one by one, ending on a single, sustained piano chord with reverb tail.)",
