Create a large and bold emoji representing a tuba. The design should feature the tuba’s iconic, large, curved brass body, with its wide bell and tubing wrapping around. Highlight the visible valves and their metal buttons, showcasing the characteristic structure of the instrument. The brass finish should be shiny, with golden tones and subtle reflective light effects to highlight its polished surface. Add soft musical notes or soundwaves emanating from the bell to evoke the deep, resonant sound of the tuba. The background should be transparent.emoji
