Chèo
Chèo (Vietnamese: [t͡ɕɛw˨˩], Chữ Nôm: 嘲) 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.Hát chèo's origins date to the 12th century during the Lý dynasty and has existed in its present form since roughly the 16th century. It derives from folk traditions, and was orally transmitted; unlike courtly theater traditions, it employs no scenery and sparse costumes and makeup. It involves a combination of traditional set pieces and improvisational routines appropriate to amateur theatre. Like the Commedia dell'arte, it often carries a message of satirical criticism of the existing social order. The traditional musical ensemble consisted of the đàn nguyệt, sáo, and the drum, though in modern recreations, more instruments are used.
A scene featuring hát chèo may be seen in the 2002 Vietnamese film Mê Thảo, Thời Vang Bóng (The Glorious Time in Mê Thảo Hamlet), directed by Việt Linh.

History
Hoa Lư – Ninh Bình is considered as the homeland of the Chèo, and its founder, Phạm Thị Trân, was a talented dancer in the royal palace during the Đinh dynasty of the tenth century. However, Chèo officially appears from the Lý dynasty (around the 11th century), flourished in the Trần dynasty (13th century). The development of Chèo has its origins when a Mongolian soldier was captured in Vietnam in the 14th century. Chèo's performance only included speaking and reciting folk songs prior to this period but influenced by the captured soldier, Chèo now is sung. In the 15th century, Emperor Lê Thánh Tông did not allow Chèo to be performed in the royal court. Chèo was only performed by peasants as a usual musical entertainment activity up to the present-day in the villages.
Chèo derives from folk music and dance, especially parody since the tenth century. Gradually, people developed various short stories based on these parodies into the longer, completed plays. Chèo was usually written by famous Confucian scholars, for example Vũ Trinh.
From loyal area's performance only, Chèo has been expanded to the North Delta and the North Central Coast (to Nghệ An province) and the Red River delta is the cradle of Vietnamese rice civilization. Whenever the crop is harvested, they organize festivals to entertain and thank the Gods for the harvest. From the first millennium BC, ancestors performed the first Chèo in the Đình yard in their village.
