贝多芬大提琴奏鸣曲宇宙主题海报
一款暗黑电影感音乐会海报提示词，将贝多芬《A 大调第 3 号大提琴奏鸣曲》（Op. 69）描绘为大提琴、三角钢琴与一只抛出的手套之间的超现实对话。
Goal: Create a cinematic classical music poster for {argument name="composer and work" default="BEETHOVEN CELLO SONATA OP. 69"}, visualizing the opening as music emerging from silence and becoming a dialogue between cello and piano.
Canvas: Wide horizontal poster, 16:9 aspect ratio, dark black background with subtle teal smoke, antique gold highlights, high-contrast chiaroscuro lighting, elegant museum-exhibition composition.
Layout: Place a large upright wooden cello on the left third, glowing warmly from below and surrounded by gold dust and abstract vertical city-like bars. Place a black grand piano on the right third, lid open, partly fragmented into geometric square blocks, backlit by a large pale cream circular moon or disk. In the center upper area, show one single thrown glove suspended in the air, arcing from the cello toward the piano, with a bright golden trail of particles, curved staff-like motion lines, and thin orbital circles around it. Use many fine vertical gold guide lines, delicate circles, spirals, and abstract musical geometry across the composition. The floor should be glossy and dark, reflecting the cello and piano faintly.
Visible text: Include exactly 5 distinct text blocks. 1) Large title on the upper left: “BEETHOVEN”, with smaller lines below: “CELLO SONATA” and “OP. 69”. 2) Small poetic block on the left: “THE MUSIC IS / BORN IN SILENCE. / IN AN INSTANT, / IT BECOMES / CONVERSATION.” 3) Small movement list below it: “I — ADAGIO CANTABILE / II — ALLEGRO VIVACE”. 4) Tiny lower-left ending phrase: “FROM NOTHING, / MUSIC.” 5) Upper-right poetic block: “A SOLITARY CELLO / THROWS A CHALLENGE / INTO THE VOID. / THE PIANO, / WITHOUT HESITATION, / CATCHES IT. / AND MUSIC / BEGINS.” Add a small monogram at the lower right: “B / 69”. Use widely spaced uppercase serif typography, ivory and muted gold lettering, with “AND MUSIC BEGINS” slightly warmer gold.
Subject details: Count exactly 2 main instruments: one cello and one grand piano. Count exactly 1 airborne glove. The cello should look realistic, varnished brown, slightly weathered, with visible strings, bridge, scroll, and endpin. The piano should be glossy black with visible keyboard and open lid, integrated with abstract cubist fragments. The glove should be tan leather or cloth, palm facing forward, lit like a symbolic challenge tossed through space.
Visual style: Sophisticated dark academia, classical concert poster, surreal cosmic stage, baroque-meets-modern graphic design, cinematic lighting, gold particle energy, fine-line diagram aesthetics, subtle grain, no people, no sheet music pages, no watermark.
Customization: If changing the theme, keep the phrase {argument name="central metaphor" default="a solitary cello throws a challenge into the void and the piano catches it"} visually represented through the arc between the two instruments. Keep the overall mood {argument name="mood" default="hypnotic, mysterious, and reverent"}.目标：为 {argument name="composer and work" default="BEETHOVEN CELLO SONATA OP. 69"} 创作一张电影感古典音乐海报，将乐曲的开篇视觉化为从寂静中涌现并转化为大提琴与钢琴之间对话的过程。
画布：宽幅横向海报，16:9 比例，深黑色背景配以微妙的青色烟雾，古金色高光，高对比度明暗对照法照明，优雅的博物馆展览式构图。
布局：在左侧三分之一处放置一把巨大的直立木质大提琴，底部散发出温暖的光芒，周围环绕着金粉和抽象的垂直城市状线条。在右侧三分之一处放置一架黑色三角钢琴，琴盖打开，部分碎片化为几何方形块，背景是一轮巨大的淡奶油色圆形月亮或圆盘。在中央上方区域，展示一只悬浮在空中的手套，从大提琴向钢琴呈弧线抛出，带有明亮的金色粒子轨迹、弯曲的五线谱式运动线条以及周围细薄的轨道圆环。构图中运用大量精细的垂直金色引导线、精致的圆圈、螺旋和抽象的音乐几何图形。地面应为光亮且深色的，隐约反射出大提琴和钢琴的倒影。
可见文字：包含 5 个明确的文本块。1) 左上角的大标题：“BEETHOVEN”，下方较小的行：“CELLO SONATA” 和 “OP. 69”。2) 左侧的小段诗意文字：“THE MUSIC IS / BORN IN SILENCE. / IN AN INSTANT, / IT BECOMES / CONVERSATION.” 3) 下方的乐章列表：“I — ADAGIO CANTABILE / II — ALLEGRO VIVACE”。4) 左下角极小的结尾短语：“FROM NOTHING, / MUSIC.” 5) 右上角的诗意文字块：“A SOLITARY CELLO / THROWS A CHALLENGE / INTO THE VOID. / THE PIANO, / WITHOUT HESITATION, / CATCHES IT. / AND MUSIC / BEGINS.” 在右下角添加一个小小的字母组合：“B / 69”。使用字间距较宽的衬线大写字体，象牙色和柔和的金色字母，其中 “AND MUSIC BEGINS” 使用色调略暖的金色。
主体细节：精确计算 2 件主要乐器：一把大提琴和一架三角钢琴。精确计算 1 只悬空的手套。大提琴应看起来写实，棕色漆面，略显风霜，可见琴弦、琴码、琴头和尾针。钢琴应为亮黑色，可见琴键和打开的琴盖，并融合了抽象的立体主义碎片。手套应为棕褐色皮革或布料，掌心朝前，灯光效果如同穿过空间抛出的象征性挑战。
视觉风格：精致的暗黑学院风，古典音乐会海报，超现实宇宙舞台，巴洛克与现代结合的平面设计，电影感灯光，金色粒子能量，细线条图表美学，微妙的颗粒感，无人物，无乐谱页面，无水印。
自定义：如果更改主题，请保持 {argument name="central metaphor" default="a solitary cello throws a challenge into the void and the piano catches it"} 这一短语通过两件乐器之间的弧线在视觉上得到体现。保持整体氛围 {argument name="mood" default="hypnotic, mysterious, and reverent"}。
