贝多芬大提琴奏鸣曲宇宙主题海报

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"}.
