Concert poster for "IMAGINE" with an iridescent hand holding a glowing rainbow musical staff, set against a sky-blue gradient background.

Minimalist concert poster in 3:4 portrait format with a soft sky‑blue to white gradient background. At the top center, place a large title reading “IMAGINE” in elegant modern pastel‑gradient typography with strong contrast for readability and a very thin black outline around each letter. The gradient should include vibrant pastel tones like lavender, peach, aqua, and pink. Increase the size and height of the title text. In the center of the poster, place a slightly smaller iridescent, glass‑like sculptural hand with shortened forearm, glowing edges and ethereal lighting. Position the hand lower toward the vertical center of the poster, increasing the distance between the hand and the title. From the hand root (where the palm meets the forearm), begin a vibrant multicolored musical ribbon with glowing notes that flows around the inner hand and wrist, twisting gently as if caught in a light breeze. The ribbon should feature shifting pastel colors with high contrast and clarity, and must not overlap any text. At the very bottom edge of the poster, add a fully centered black sans‑serif text block. The text block should read in bold capitals, each line fully centered: “CHORKONZERT”, then “PLICAE VOCALIS”, then “SOEST”, then a reduced vertical gap, followed by also bold text in smaller font: “Samstag, 21. November 2026”, then “17 Uhr”, then “Johanneskirche Soest”. Maintain clean digital art, calm and inspiring mood, balanced negative space, and a modern classical concert Ver mais
