Create an elegant and festive emoji collage representing keyboard instruments, styled like a heraldic emblem. The design should feature a central focal point of black and white piano keys, arranged in a semi-circular or shield-like shape. Around the piano keys, add intertwining musical notes that form flowing ribbons, creating a dynamic and celebratory atmosphere. The design should be professional, with polished silver and gold accents on the keys and notes, highlighting the luxury and sophistication of the instruments. Add subtle shading and lighting effects to give the design a refined, 3D appearance. The background should remain transparent, and the overall feel should evoke grandeur, artistry, and a sense of celebration.emoji
