Chèo is a form of generally satirical musical theatre, often encompassing dance, traditionally performed by Vietnamese peasants in northern Vietnam. It is usually performed outdoors by semi-amateur touring groups, stereo-typically in a village square or the courtyard of a public building, although it is today increasingly also performed indoors and by professional performers. Chèo stage art is one of the great cultural heritage of the Vietnamese folk treasure. Chèo has been a popular art form of the Vietnamese people for many generations and has fostered the national spirit through its lyrical content.
