Chầu văn

Hát chầu văn (Vietnamese: [háːt cə̂w van], chữ Nôm: 喝朝文), or in secular form hát văn (喝文),[1] is a traditional folk art of northern Vietnam which combines trance singing and dancing.

[2] Its music and poetry are combined with a variety of instruments, rhythms, pauses, and tempos.

[3][4][5] Hát chầu văn originated in the 16th century and spread quickly.

[6] The main musical instrument used in hat van performance is the đàn nguyệt or moon-shaped lute.

The singing and dance in non-religious form is hát văn ("sung literature") without the word chầu ("to have an audience with someone of higher power", "to perform a service and pay homage to a deity").
