I think the formation of chorus is inevitably related to the songs sung, but if you want to be creative, you have to spend a lot of time to make the judges shine. From your brother's point of view, I still think we can arrange the formation with special patterns, such as hearts, smiling faces, doves of peace (Sun Rong once seemed to win the prize by this formation) and so on. If you want to express an idea, you can also try to express it in words. But I don't think static formation alone is enough, because that's what the chorus (brother, I guess) uses now. This requires you to be innovative. My suggestion is that you can change the formation in the process of singing, and you can change from one shape to another. This process must be skilled and the time should be as short as possible, otherwise it will give people a sense of confusion. There are 52 girls and 6 boys, and you are required to give priority to the position of boys. While singing, you can also set some actions. If you can, you should add more to your clothes. All the above are on paper, and the specific implementation depends on your sister. Wish you success! I support you! ! !
