"Create a short, 3-5 second audio jingle for a children's audio story. The jingle should have a cheerful and adventurous tone, with a playful marimba or soft piano melody, light percussion, and a gentle rising sound effect to evoke excitement and curiosity. Avoid overly festive or seasonal elements. The jingle should feel magical yet neutral, fitting various settings like a circus, a farm, or a forest. Ensure it is simple, memorable, and engaging for young children, with a clean fade-out to transition smoothly into the story."
