Are dance movements or dance accompaniment, poetry recitation, formation change, etc. allowed in regular chorus competitions? What are the formal rules?
Dance movements or accompanying dances are not allowed in official competitions, and simple sign language movements are still allowed. As for recitation and formation changes, it is still allowed, but not too much, because it is a chorus competition or mainly singing. School chorus rules generally take classes as units, with about 50 people standing in four rows, which can be arranged in various formations. There are many "fan" shapes, and the word "D" stands in the first row. In the process of singing, according to the emotional expression of the song, there are appropriate actions, such as: shaking the queue left and right, waving flowers in your hand, etc.
