Create a professional and elegant emoji collage symbolizing wind instruments, using a combination of copper, white metal, and black wood. The design should feature iconic instruments like a trumpet, saxophone, tube, oboe, and horn. Each instrument should be represented with its key elements clearly visible. Each instrument should be designed with realistic textures, including the gleam of metal and the deep, rich tone of black wood. Arrange the instruments in a balanced and harmonious way, making sure the elements are easily recognizable. Use metallic gold, silver, and copper tones with black wood accents. The background should be transparent to highlight the instruments.emoji
