  "lyrics": "[intro]\n(Energy: 2/10)\n(Chords: F#m - D - A - E)\n(Inst: Signature synthesized guzheng/pipa melody enters, bright and clean. Ambient pad underneath.)\n(Motif-Anatomy: Pentatonic descending phrase, starts on 5th, short-short-long rhythm.)\n(Mix: Lead synth centered and upfront, creating a sense of anticipation.)\n\n[verse]\n(Energy: 3/10)\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Gentle, clear chest voice, storytelling tone, precise syllable enunciation, almost like recitation.)\n(Phrase-Structure: Symmetrical 4-bar phrasing, poetic breath spacing.)\n(Inst: Vocals enter. Sub-bass and a simple electronic beat (kick, hats) provide a soft foundation. Guzheng synth plays fills at the end of vocal phrases.)\n(Transition: Light cymbal swell into chorus.)\n手中雕刻生花\n刀锋千转蜿蜒成画\n盛名功德塔\n是桥畔某处人家\n春风绕过发梢红纱\n刺绣赠他\n眉目刚烈拟作妆嫁\n\n[chorus]\n(Energy: 6/10)\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Voice becomes more open and sustained, higher in register, emotion builds but remains controlled.)\n(Contour-&-Range: Melodic leap upwards from the verse, creating a memorable, soaring contour.)\n(Inst: Full drum kit with clap on 2 & 4 enters. Orchestral string pads swell, adding width. Guzheng synth doubles parts of the vocal melody.)\n(Mix: Vocals remain central, layered with subtle backing harmonies. The soundscape is fuller and wider.)\n轰烈流沙枕上白发\n杯中酒比划\n年少风雅鲜衣怒马\n也不过一刹那\n难免疏漏儿时檐下\n莫测变化\n隔却山海\n转身从容煎茶\n\n[interlude]\n(Energy: 3/10)\n(Chords: F#m - D - A - E)\n(Inst: Drums and bass drop out, leaving only the main guzheng synth hook and ambient pads, echoing the intro.)\n(Transition: Beat re-enters softly to lead into the next verse.)\n\n[verse]\n(Energy: 4/10)\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Similar to first verse but with slightly more dynamic intensity, building anticipation for the second chorus.)\n(Inst: The rhythm section is slightly more present than in the first verse. Light string pads continue underneath.)\n手中雕刻生花\n刀锋千转蜿蜒成画\n盛名功德塔\n是桥畔某处人家\n春风绕过发梢红纱\n刺绣赠他\n眉目刚烈拟作妆嫁\n\n[chorus]\n(Energy: 7/10)\n(Chords: F#m - D - A - E)\n(Vocal-Perf: Fullest vocal performance, emotionally resonant, sustained high notes with natural vibrato.)\n(Inst: All elements at full intensity. Drums are driving, strings are prominent, guzheng synth melody is powerful and interwoven with the vocal.)\n(Mix: A dense, emotional, and wide mix. Vocal harmonies are more pronounced.)\n轰烈流沙枕上白发\n杯中酒比划\n年少风雅鲜衣怒马\n也不过一刹那\n难免疏漏儿时檐下\n莫测变化\n隔却山海\n转身从容煎茶\n\n[bridge]\n(Energy: 8/10)\n(Chords: D - E - F#m - A)\n(Vocal-Perf: The emotional peak. Voice is at its highest range, conveying a sense of profound declaration and longing.)\n(Contour-&-Range: A new, anthemic melody with a wide range, serving as the song's ultimate hook.)\n(Inst: Rhythm section is powerful. Guzheng synth plays a counter-melody. The overall texture is at its peak.)\n(Transition: Music holds on the final chord, then a soft decrescendo into the outro.)\n一生长\n重寄一段过往\n将希冀都流放\n可曾添些荒唐\n才记得你的模样\n一身霜\n谁提笔只两行\n换一隅你安康\n便销得这沧桑\n你还在我的心上\n\n[outro]\n(Energy: 2/10)\n(Chords: F#m - D - A - E)\n(Inst: All elements fade out except for the signature synthesized guzheng melody and a soft ambient pad. The melody repeats once and fades to silence.)\n(Mix: A slow fade-out, leaving a feeling of lingering memory.)",
