Create an image of a vibrant watercolor illustration featuring a large, striking blue butterfly at the center, surrounded by delicate, colorful flowers in shades of pink, orange, and teal. In the background, incorporate softly blurred musical notes on sheet music, blending harmoniously with the floral elements. The overall composition should evoke a sense of tranquility and creativity, with gentle splashes of pastel colors and a dreamy, ethereal quality.
