  "prompt": "Genre: Instrumental Neo-Soul / Lo-Fi Jazz; BPM: 70; Key: C# Major (with extensive jazz harmony); Rhythm: Free-time piano intro flows into a slow, laid-back hip-hop groove; a sparse kick and brushed snare with a strong behind-the-beat, improvisational feel; Instruments: Grand piano (close-mic'd, captures hammer action), deep synth bass (subtle, foundational), lo-fi drum kit (brushed snare texture); Vocals: Male, soft and breathy tenor with a gentle rasp, frequent use of intimate close-mic falsetto, processed with heavy reverb and delay; Mood: Sitting alone in a dimly lit jazz club after closing time, rain streaking down the large window overlooking a quiet city street; Highlight: The sudden, resonant low piano chord that drops into the arrangement unexpectedly, followed by a rapid ascending arpeggio, creating a powerful emotional swell.",
  "title": "坐得端正",
  "lyrics": "[intro]\n(Mix: Wide stereo field focused on the intimate, central piano. Warm analogue saturation across the master. Frequencies are balanced with a gentle low-end roll-off to leave space for bass, and a silky, non-harsh high-end. Light bus compression to glue elements.)\n(Inst: Solo grand piano, close-mic'd, with audible pedal and hammer mechanics.)\n(Chords: F#maj7 - G#7sus4 - A#m7 - C#maj7)\n\n[verse]\n(Vocal-Perf: Enters with a gentle, breathy chest voice, intimate close-mic presence, almost a whisper.)\n(Inst: Grand piano continues its improvisational chording. A low, warm synth pad fades in, providing a subtle harmonic bed.)\n(Melody-Rhythm: Vocal phrases are sparse, starting late after beat 2 and ending with long decays, weaving around the piano's rhythm.)\n(Chords: A#m7 - D#m9 - G#7 - C#maj7)\n把手放得太平了\n桌面的纹路我数过三遍又三遍\n房间的光不偏不正落在墙角\n我坐在这里什么都没有想\n\n[chorus]\n(Mix: Stereo image widens. Vocal reverb tail becomes more prominent.)\n(Vocal-Perf: Shifts from chest voice to a delicate, airy falsetto. Dynamics lift slightly but remain gentle.)\n(Inst: A slow, laid-back lo-fi beat enters; soft kick on 1 and 3, brushed snare with ghost notes on 2 and 4. A deep, round sub-bass plays root notes, locking in the groove.)\n(Hook-DNA: A syncopated 3-note vocal motif lands on the 'and' of 1, repeating twice before a longer tail phrase; anchored around the 5th and resolving to the 3rd.)\n(Melody-Contour: Gentle arch shape, ascending minor 3rd from 3 to 5 and descending back down.)\n(Melody-Harmonic-Tension: Vocal melody holds the major 7th over the tonic C#maj7 chord for a full beat, creating a sweet tension before resolving downwards stepwise.)\n(Chords: F#maj7 - C#maj7 - A#m7 - G#7sus4)\n越不想想起来\n就坐得越端正\n背脊挺得笔直\n像在等一个不会来的人\n\n[interlude]\n(Inst: Drums and bass drop out, leaving a virtuosic, arpeggio-heavy piano solo. The ambient pad swells slightly in the background.)\n(Sound-Design: A subtle vinyl crackle sample is introduced for texture.)\n\n[verse]\n(Vocal-Perf: Returns to chest voice, but with slightly more confidence and less breathiness than the first verse.)\n(Inst: The full rhythm section re-enters, maintaining the relaxed groove. Piano plays more sparsely, leaving space for the vocal.)\n(Melody-Rhythm: Vocal phrasing becomes slightly more on-the-beat, creating a subtle sense of forward momentum.)\n(Chords: A#m7 - D#m9 - G#7 - C#maj7)\n呼吸浅了一格就听见了走廊\n有脚步声近了又往别处拐去\n手指压着指节骨头轻轻作响\n我还是什么都没有想\n\n[chorus]\n(Mix: Backing vocal layers are added, panned wide, creating a lush, immersive space.)\n(Vocal-Perf: Falsetto lead vocal is layered with two lower harmony parts, sung with the same airy texture.)\n(Inst: Beat continues, but a soft, shaker-like percussion adds a new 16th-note subdivision.)\n(Hook-DNA: The 3-note motif returns, now harmonized. The final tail phrase extends an extra two bars.)\n(Melody-Harmonic-Tension: The tension on the major 7th over the tonic chord is heightened by the harmony vocals, which create a richer cluster before resolution.)\n(Chords: F#maj7 - C#maj7 - A#m7 - G#7sus4)\n越不想想起来\n就坐得越端正\n背脊挺得笔直\n像在等一个不会来的人\n\n[bridge]\n(Mix: All rhythmic elements drop out. The mix becomes very sparse and reverb-drenched.)\n(Vocal-Perf: A single, exposed vocal line, almost spoken, heavy with reverb.)\n(Inst: Piano plays only sustained, shimmering chords. The synth pad is the main harmonic element.)\n(Melody-Harmonic-Tension: Harmony remains static on a D#m9 chord for four bars, while the vocal melody slowly wanders and deliberately avoids resolving to a chord tone, creating a feeling of suspension before the final chorus.)\n(Chords: D#m9 - G#13)\n不是不知道\n是太知道了\n所以才把手放得这样平\n越不想想起来 就坐得越端正\n\n[outro]\n(Inst: Beat deconstructs, leaving only a kick drum on every other bar. Piano plays a final, sparse version of the main theme, then single notes with long pauses. The synth pad and vinyl crackle slowly fade to silence.)\n(Transition: A final, resonant piano chord rings out and its reverb tail is the last thing heard.)",
