  "lyrics": "[intro]\n(Chords: F#m - E - D - C#m)\n(Transition: Gentle guzheng glissando entry over ambient wind sounds. Sound-Design: Soft wind, distant reverb for initial guzheng pluck.)\n(Motif-Anatomy: Descending pentatonic scale fragment, long-short rhythmic grouping, with delicate grace notes. Chinese-Style Gene: Clear pentatonic phrasing, expressive glissando.)\n(Phrase-Structure: Free-rhythm opening phrase, then established steady 4/4 subtle pulse for backing. Call-and-response between guzheng and erhu.)\n(Contour-&-Range: Initial guzheng phrase starts mid-range, descends with a melancholic feel. Erhu enters in higher register, adding a soaring, lamenting quality.)\n(Vocal-Perf: No vocals in intro.)\n(Mix: Guzheng prominent, dry and clear. Erhu slightly behind, blended with strings. Ambient sounds very subtle. Modern elements not yet present.)\n(Inst: Guzheng plays main melodic theme, erhu provides counter-melody. Subtle orchestral strings emerge.)\n\n[verse]\n(Chords: F#m - C#m - D - E)\n(Transition: Subtle entry of soft drums and bass, establishing the 4/4 groove. Sound-Design: Seamless blend, adding a rhythmic pulse without losing the ambient feel.)\n(Motif-Anatomy: Vocal melody built on F# minor pentatonic, often starting on the 5th and descending, simple syllabic rhythm. Chinese-Style Gene: Vocal melody follows pentatonic lines, clear articulation of each character.)\n(Phrase-Structure: Symmetrical 4-bar phrases, question-answer structure in the lyrics. Melodic phrases are relatively short and self-contained.)\n(Contour-&-Range: Vocal range stays within a comfortable mid-tenor register, smooth contour, focused on conveying narrative.)\n(Vocal-Perf: Male tenor, clear, slightly melancholic tone. Poetic diction, each syllable distinct and expressive. Focus on narrative clarity.)\n(Mix: Vocals centered, gentle hall reverb. Guzheng continues as a delicate counterpoint. Drums and bass are soft, supportive. Strings provide harmonic warmth.)\n(Inst: Vocal carries main melody. Guzheng light accompaniment. Drums, bass, strings for harmonic and rhythmic support.)\n凉风又吹过窗沿\n你说不见便不见\n多少年\n那些话压进心间\n\n[pre-chorus]\n(Chords: D - E - F#m - C#m)\n(Transition: Slight increase in rhythmic intensity, strings swell. Sound-Design: Subtle drum fill leading into the build-up.)\n(Motif-Anatomy: Ascending melodic line, building tension by reaching higher notes within the pentatonic scale. Chinese-Style Gene: Use of ascending melodic steps to build emotional anticipation, often resolving to a stronger chord.)\n(Phrase-Structure: Builds over 2-4 bars, creating a sense of anticipation towards the chorus. Longer, more sustained notes in the vocal melody.)\n(Contour-&-Range: Vocal ascends to a slightly higher register, conveying a sense of longing and questioning. Peaks before the chorus.)\n(Vocal-Perf: Male tenor, clear and sustained notes, growing emotional intensity. Delivers lyrics with poignant sincerity. Maintains poetic diction.)\n(Mix: Vocals still centered, reverb slightly more noticeable. Strings become more prominent, drums add more weight.)\n(Inst: Vocal primary. Strings provide main harmonic drive. Drums slightly more active.)\n想问你近来可好\n开口又咽了\n这煎熬\n没出口的爱往哪跑\n\n[chorus]\n(Chords: F#m - D - A - E - F#m - C#m - D - E)\n(Transition: Full band entry, strong rhythmic drive. Sound-Design: Orchestral hit or subtle cymbal crash marks the chorus entrance.)\n(Motif-Anatomy: Main melodic hook: strong, memorable pentatonic phrases with a soaring quality, often starting on higher notes and descending. Chinese-Style Gene: Melodic leaps followed by graceful descents, maintaining pentatonic character, epic feel.)\n(Phrase-Structure: Powerful, anthemic phrasing, clear resolution. Each line feels conclusive, building to a strong emotional statement. More complex, extended phrases.)\n(Contour-&-Range: Vocal reaches its highest and most powerful range, utilizing head voice/falsetto-like timbre for emotional impact. Wide dynamic and pitch range.)\n(Vocal-Perf: Male tenor, full and resonant, with powerful delivery. Employs classical Chinese vocal style for expressive impact, especially on high notes. Maintains poetic clarity while conveying strong emotion.)\n(Mix: Vocals are at their loudest and most present. Full orchestral strings, drums, bass, and classical instruments create a rich, layered sound. Clear separation of elements.)\n(Inst: Vocal, guzheng, erhu, strings, drums, bass all contribute to the full texture. Erhu often doubles or provides counterpoint to the vocal melody.)\n爱你的心无处安放便随你走\n遇见你那年不知把自己丢\n若干年后\n翻出那个名字还是会抖\n\n[interlude]\n(Chords: F#m - E - D - C#m)\n(Transition: Drums and bass pull back slightly, classical instruments take center stage. Sound-Design: Gentle fade of modern elements, allowing classical core to shine.)\n(Motif-Anatomy: Echoes fragments of the intro and chorus melodies, but in a more improvisational, reflective manner. Chinese-Style Gene: Focus on the expressive and virtuosic capabilities of classical instruments, allowing rubato phrasing.)\n(Phrase-Structure: Less strict rhythm, showcasing the melodic interplay between guzheng and erhu. More embellishments and melodic flourishes.)\n(Contour-&-Range: Guzheng and erhu explore higher and lower registers, demonstrating their full emotional range. Melodic lines are intricate and flowing.)\n(Vocal-Perf: No vocals in interlude.)\n(Mix: Guzheng and erhu are very prominent and detailed. Strings provide a sustained backdrop. Drums and bass are minimal or absent, re-entering gently towards the end.)\n(Inst: Guzheng and erhu perform a dual melodic improvisation, backed by subtle strings and minimal rhythm section.)\n\n[chorus]\n(Chords: F#m - D - A - E - F#m - C#m - D - E)\n(Transition: Gradual re-entry of full rhythm section and orchestral strings, building back to full intensity. Sound-Design: Crescendo from the interlude, re-introducing drums with a powerful fill.)\n(Motif-Anatomy: Repeated main melodic hook, reinforcing its emotional impact. Chinese-Style Gene: Strong, memorable pentatonic phrases, delivering the core emotional message with full power.)\n(Phrase-Structure: Identical to the first chorus, providing structural familiarity and emotional climax.)\n(Contour-&-Range: Vocal again reaches its powerful peak, full range utilized. Consistent with first chorus for impact.)\n(Vocal-Perf: Male tenor, powerful and passionate delivery. Emphasizes the heroic and devoted aspects of the lyrics. Sustained high notes with clarity.)\n(Mix: Full, rich mix with all elements prominent, similar to the first chorus but with slightly more dynamic intensity.)\n(Inst: Full band texture with vocal, classical instruments, and modern elements driving the melodic and harmonic core.)\n爱你的心无处安放便随你走\n遇见你那年不知把自己丢\n若干年后\n翻出那个名字还是会抖\n\n[outro]\n(Chords: F#m - E - D - C#m - F#m)\n(Transition: Gradual fade out, returning to a more sparse, melancholic texture. Sound-Design: Reverb trails, soft drum decay, final guzheng pluck.)\n(Motif-Anatomy: Final lyrical lines delivered with a sense of resignation or peace, melody gently descends and sustains. Chinese-Style Gene: Melodic phrases resolve cleanly, leaving a lingering emotional resonance.)\n(Phrase-Structure: Shortened, concluding phrases. Focus on key emotional statements, leading to a gentle, reflective end.)\n(Contour-&-Range: Vocal returns to a mid-range, softer dynamic, a lingering sense of emotion. Ends on a sustained, poignant note.)\n(Vocal-Perf: Male tenor, soft and tender, conveying a sense of enduring commitment. Words are clear, but delivery is more intimate and reflective.)\n(Mix: Vocals remain clear, but dynamic softens. Drums and bass fade. Guzheng and erhu re-emerge for the final melodic statements, with fading strings and subtle ambient elements.)\n(Inst: Vocal, then final delicate guzheng and erhu melodic fragments, with fading strings and subtle ambient elements.)\n你是我记忆里最深的光\n哪怕走散也不会遗忘\n就这样吧\n把你的笑容藏进胸膛",
