Koothu or Therukoothu (jwalith) (கூத்து), is an ancient art, where artists play songs with dance and music in storytelling the epics, performed in Tamil; it is a folk art originated from the early Tamil country. More precisely Koothu refers to either Terukuttu (Tamil:தெருக்கூத்து) or Kattaikkuttu. The terms Terukkuttu and Kattaikkuttu are often used interchangeably in modern times; however, historically, the two terms appear to have distinguished, at least in certain villages, between two different kinds of performance: while Terukkuttu referred to mobile performances in a procession, Kattaikkuttu denotes overnight, narrative performances at a fixed performance space. Koothu as a form of entertainment reached its peak hundreds of years ago in Tamil Nadu, as mentioned in the Sangam texts about the development of iyal (literature), isai (music) and natagam (drama). Going beyond just a means of entertainment, koothu educates the rural people about religion and their history. Koothu is an informal dance structure, in which performances generally depict scenes from ancient epics such as Ramayana, Mahabharata and Tamil classical epics. There is traditionally no spoken dialogue, only songs. Artists are trained to sing in their own voice and in a high pitch to reach the entire crowd, since no amplification technology is used. The artists are dressed up with complex heavy costumes and have a very bright elaborated makeup. They put on towering head dresses, sparkling shoulder plates and wide colorful skirts. Traditionally, this theatre form has been predominantly male, though in modern times more females have been included (for example Girl's Theatre at the Kattaikkuttu Gurukulam). Types of koothu include Nattu Koothu, Kuravai Koothu, and Valli Koorhu, which are about the state and culture of different peoples in Tamil country; Samaya Koothu showcases religious topics, while Porkaala Koothu, Pei Koothu, and Thunangai Koothu are focused on the martial arts and war of the country. Another important art form Chakyar Koothu, is very popular in Kerala.
