**Minimalist premium sheet music cover for a contemporary concert Mass. Elegant European classical music publishing aesthetic inspired by Bärenreiter, Henle Verlag and Carus-Verlag. Large negative space, sophisticated typography layout, off-white textured paper background with subtle ivory tones. A single abstract sacred geometric element in the center: thin golden circular halo intersected by delicate architectural lines reminiscent of Gothic cathedral vaults, without explicit religious symbols. Fine embossed details, understated luxury, museum-quality print design. Modern Swiss graphic design meets classical music publishing. No photographs, no illustration, no people, no dramatic lighting, no ornaments, no gradients, no decorative borders. Extremely clean composition, balanced margins, timeless, refined, premium edition, matte paper, editorial design, vector precision, minimal color palette (ivory, warm gray, black, muted gold). Leave generous empty space for title and composer. Vertical A4 ratio. High-resolution print-ready cover.
