ملصق موسيقي هندسي بالطراز السويسري

Clean Swiss modernist typography poster for an experimental music event, vertical 3:4 composition on warm off-white paper with subtle print texture. Layout uses a strict grid, thin gray construction lines, a thin vertical center line, and a horizontal divider across the lower third, creating balanced asymmetry with generous negative space. Abstract sound-wave geometric composition in the upper half: a large set of fine concentric gray circles centered slightly above the middle; a thick black partial ring on the upper right; a solid red central circle partially overlapped by white and black segments; a cluster of thin vertical gray lines near the upper-left edge; a cluster of thin horizontal gray lines crossing from the left into the center; a thick red quarter-arc sweeping upward from the lower left; a row of exactly 7 small black dots horizontally aligned to the right of the main circle; and a black semicircular shape cropped along the left margin below the horizontal line. A single small solid blue circle sits below the central cluster as an accent. Typography in the lower right block, left-aligned, set in bold uppercase Helvetica-style sans-serif: Main headline: "[SONIC STRUCTURES]" Small subtitle below headline: "[experimental music series]" Divider line, followed by bold red uppercase text: "[ZÜRICH]" and "[12–14 OCT 2026]" Second divider line, followed by small black text: "[Tonhalle Forum / 20:00]" and "[electronic / chamber / improvisation]" Style: Bauhaus-inspired Swiss International Typographic Style, crisp flat vector geometry, high-contrast palette of black, red, single blue accent, gray, and off-white. No gradients, no drop shadows, no photographic textures, no decorative borders.
