Kunqu, also known as Kunju, Kun opera or Kunqu Opera, is one of the oldest extant forms of Chinese opera. It evolved from the Kunshan melody, and dominated Chinese theatre from the 16th to the 18th centuries. The style originated in the Wu cultural area. It is listed as one of the Masterpieces of the Oral and Intangible Heritage of Humanity by UNESCO since 2001.
Kunqu was developed during the late Ming Dynasty (14th century), and a famous early pioneer was Gu Jian of Qiandeng town in Kunshan. Kunqu has influenced on many other Chinese theatre forms, including Jingju (Peking Opera). Its emergence ushered in the second Golden Era of Chinese drama.
Kun Qu songs are accompanied by a bamboo flute, a small drum, wooden clappers, gongs and cymbals, all used to punctuate actions and emotions on stage.
