  "lyrics": "[intro]\n(Chords: F#m - D - A - E)\n(Inst: Solo xiao plays a breathy, pentatonic hook over a sparse synth pad and gentle string swells.)\n(Motif-Anatomy: Melancholic descending pentatonic phrase, breathy attack, long vibrato tail on final note.)\n(Mix: Xiao is centered, dry, and intimate. Wide reverb on pads.)\n\n[verse]\n(Chords: F#m - D - A - E)\n(Transition: Acoustic drum kit with R&B groove enters. Electric bass and acoustic guitar join.)\n(Vocal-Perf: Gentle chest voice, narrative tone, clear enunciation of each syllable, restrained emotion.)\n(Phrase-Structure: Symmetrical 4-bar phrasing, follows the chord changes closely.)\n(Contour-&-Range: Vocal melody stays within a narrow, comfortable mid-range.)\n孤帆落日映寒沙\n渡口无人候归家\n笛声一折诉天涯\n旧年霜雪覆了檐下花\n\n[verse]\n(Chords: F#m - D - A - E)\n(Inst: Xiao plays subtle fills at the end of vocal phrases.)\n(Vocal-Perf: Intensity builds slightly, introduces a touch of breathiness for emotion.)\n(Contour-&-Range: Same range as first verse, but with more dynamic variation.)\n素笺半卷墨迹斜\n字字皆是问君话\n月沉水底映孤霞\n此去山长路比泪更无涯\n\n[chorus]\n(Chords: D - A - E - F#m)\n(Transition: Orchestral strings swell, adding significant emotional weight. Full texture.)\n(Vocal-Perf: Vocal leaps into a higher, more powerful register. Open vowels on sustained notes. Emotion peaks.)\n(Contour-&-Range: Melody features a significant upward leap on the downbeat, creating an anthemic feel.)\n(Highlight: Xiao plays a counter-melody that weaves around the main vocal line.)\n烟散 散不尽\n雁过 过不返\n问这江水几时休\n送走了春又送走了秋\n留不住的人啊 留不住的手\n只余箫声诉旧愁\n\n[interlude]\n(Chords: F#m - D - A - E)\n(Inst: Xiao takes the lead again, improvising on the main hook melody over the full R&B rhythm section. Vocal ad-libs enter in the second half.)\n(Mix: Xiao is brought forward in the mix, becoming the primary focus.)\n(Sound-Design: A subtle reverse cymbal swell leads into the next section.)\n\n[verse]\n(Chords: F#m - D - A - E)\n(Transition: Drums hit harder, full dynamic intensity.)\n(Vocal-Perf: Most passionate delivery, ad-libs with falsetto tones. Background harmonies added for thickness.)\n(Contour-&-Range: Vocal pushes to the top of the range, conveying desperation and heartbreak.)\n亭外骤雨打芭蕉\n一声一声入骨销\n灯芯将尽影摇摇\n梦里共游的人已成烟渺\n\n[chorus]\n(Chords: D - A - E - F#m)\n(Transition: Drums hit harder, full dynamic intensity.)\n(Vocal-Perf: Most passionate delivery, ad-libs with falsetto tones. Background harmonies added for thickness.)\n(Contour-&-Range: Vocal pushes to the top of the range, conveying desperation and heartbreak.)\n烟散 散不尽\n雁过 过不返\n问这江水几时休\n送走了春又送走了秋\n留不住的人啊 留不住的手\n只余箫声诉旧愁\n\n[outro]\n(Chords: F#m - D - A - E)\n(Inst: Music gradually fades. Rhythm section drops out, leaving only the solo xiao, strings, and a final vocal ad-lib.)\n(Vocal-Perf: Final phrase sung in a soft, breathy falsetto, trailing off.)\n(Mix: Heavy reverb applied to the final xiao note, letting it decay into silence.)",
