[Is_MAX_MODE:MAX][QUALITY:MAX][REALISM:MAX][REAL_INSTRUMENTS:MAX]

[Intro][Establish Motif][Solo Piano Only]
(soft dynamic, define descending third plus chromatic delayed resolution clearly, spacious broken chords)

[Exposition][Theme A][Extended][Motivic Recall]

[Ornamented Restatement][Chromatic Delay]
(embellished melody, gentle rubato, delayed resolutions intensify expression)

[Development I][Extended][Rhythmic Compression]
(motif rhythm shortened, increased note density, gradual tension rise without sudden climax)

Short Post:
八分鐘鋼琴長夜敘事。🌌主題回歸四次，雙高潮定格舞台。

這是一首挑戰長篇結構掌控力的鋼琴夜曲。開場三度動機即刻建立記憶點，八分鐘內多次回歸與變形，形成清晰主題鏈。節奏壓縮與音程擴張分段推進張力，避免一次性爆發。雙高潮設計在全鍵盤音域完成到達感，最終以正格終止與大型延長定格舞台，拒絕淡出，完成競賽式長弧線敘事。

本曲以長夜為敘事空間，核心動機為下行三度結合上行半音延遲解決。開場即建立可辨識旋律輪廓，確保評審於三十秒內記住主題。全曲透過多次動機回歸與變形形成長篇記憶鏈。發展段採階段式張力推進，而非瞬間爆發。雙高潮設計強調到達感與音域擴張，最終以正格終止與大型延長定格舞台。結構美學參照 John Williams 對主題再現與高潮節點的掌控邏輯，但完全轉化為純鋼琴語法。

長篇浪漫夜曲架構，三段體擴展為多層發展弧線。質地必須透明，嚴禁任何配器暗示。強調主題多次回歸與變形。張力透過節奏密度與和聲延遲逐步堆疊。雙高潮設計需清晰區分層級。整體必須維持八分鐘以上結構完整性。

鋼琴僅限單一原聲音色。
右手旋律保持歌唱性與清晰發音。
左手分解和弦流動但避免混濁。
低音支點段需穩定延長形成壓力。
對位段落強調聲部分離與控制踏板。
高潮全鍵盤投射但保留動機辨識。

None。

引子確立動機 → 主題呈示 → 裝飾再現 → 第一發展（節奏壓縮）→ 對位 → 第二發展（音程擴張）→ 長弧線預高潮 → 第一高潮 → 主題回歸 → 延伸發展 → 最終高潮 → 再現收束 → 正格終止與大型延長。
