However, in subsequent dynasties, the "guan" fell out of use in court music but became very popular in folk ensembles. It plays an important part in the wind-and-percussion ("chuida" or "guchui") ensembles that play on traditional festivals and celebratory occasions and is still popular in the wind band music of northern China, as well as in some other Chinese regions. In the Beijing opera orchestra, the "guan" is used to depict military scenes along with the "suona" and other percussion instruments.
