Create an elegant and artistic emoji that represents music arrangement and orchestration. The design should feature musical notes, a set of piano keys, a drum set, and an electric guitar to symbolize the diverse elements of orchestration and arrangement. Include a conductor's baton to emphasize the role of a conductor in bringing all the instruments together. Use a mix of rich colors like gold, silver, and deep blue for sophistication, and add flowing lines to represent the harmony between different instruments. The background should be transparent. emoji
