Students don't have to worry about' I often participate in such performances'. My personal opinion is for reference only' It is more appropriate to wear a black tuxedo as a conductor. The costume of the chorus echoes the theme of the day's content, but it has nothing to do with the costume of the conductor.' The conductor should take a solemn black tuxedo as the best policy. I'm not a conductor major, but I often perform on the same stage. Say the gesture first: I should give you a signal at the beginning. Gestures are like playing the piano. Under normal circumstances, the accompaniment comes out first. At this time, the state of both hands can't be the same. One side of the movement is slightly larger and the other side is slightly smaller. When the chorus part comes out, you can give a very clear gesture together. This is probably another thing: if you don't have many performance tasks, you don't need to buy a tuxedo, because the price of a dress with good fabric and good style is not unreasonable. If you are a non-professional student, I suggest that you can rent a place for dancing supplies or clothes, which is cheap and good.
