Chhau dance (Oriya: ଛଉ ନାଚ,Bengali: ছৌ নাচ) is a genre of Indian tribal martial dance which is popular in the Indian states of Odisha, Jharkhand and West Bengal. There are three subgenres of the dance, based on its places of origin and development, Seraikella Chhau, Mayurbhanj Chhau and Purulia Chhau.
It is believed by some modern scholars that the word Chhau is derived from Sanskrit Chāya (shadow, image or mask), but according to Sitakant Mahapatra, it is derived from Chhauni (military camp).
Features of the Chhau 
The Chhau dance is mainly performed during regional festivals, especially the spring festival of Chaitra Parva which lasts for thirteen days and in which the whole community participates. The Chhau blends within it forms of both dance and martial practices employing mock combat techniques (called khel), stylized gaits of birds and animals (called chalis and topkas) and movements based on the chores of village housewives (called uflis). The dance is performed by male dancers from families of traditional artists or from local communities and is performed at night in an open space, called akhada or asar, to traditional and folk music, played on the reed pipes mohuri and shehnai. A variety of drums accompany the music ensemble including the dhol (a cylindrical drum), dhumsa (a large kettle drum) and kharka or chad-chadi. The themes for these dances include local legends, folklore and episodes from the Ramayana and Mahabharata and other abstract themes.
The Chhau dance is mainly performed by the Munda, Mahato, Kalindi, Pattnaik, Samal, Daroga, Mohanty, Acharya, Bhol, Kar[disambiguation needed], Dubey[disambiguation needed], and Sahoo communities. The musical accompaniment for the dance is provided by people of communities known as Mukhis, Kalindis, Ghadheis and Dhadas who are also involved in the making of the instruments. Masks form an integral part of Chhau Dance in Purulia and Seraikella where the craft of mask-making is undertaken by communities of traditional painters known as Maharanas, Mohapatras and Sutradhars. The knowledge of dance, music and mask-making is transmitted orally.
Three styles of Chhau 
The Seraikella Chhau developed in Seraikela, the present day administrative headquarters of the Seraikela Kharsawan district of Jharkhand, the Purulia Chau in Purulia district of West Bengal and the Mayurbhanj Chhau in Mayurbhanj district of Odisha. The most prominent difference among the three subgenres is regarding the use of masks. While, the Seraikela and Purulia subgenres of Chhau use masks, the Mayurbhanj Chhau uses none.
The Seraikella Chhau's technique and repertoire were developed by the erstwhile nobility of this region who were both its performers and choreographers. The Mayurbhanj Chhau is performed without masks and is technically similar to the Seraikella Chhau. The Purulia Chhau too uses masks and it exhibits the spontaneity of folk art. This is because unlike the Seraikella and Mayurbhanj Chhau, which enjoyed royal patronage, the Purulia Chhau was sustained and developed by the people themselves.
In 2010 the Chhau dance was inscribed in the UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.
Measures to safeguard the dance 
The Government of Odisha established a Government Chhau Dance Centre in 1960 in Seraikella and the Mayurbhanj Chhau Nritya Pratisthan at Baripada in 1962 since the abolition of princely states made it difficult for the local communities to sustain these traditions. These institutions engage in training involving local gurus, artists, patrons and representatives of Chhau institutions and sponsor performances. The Chaitra Parva festival, significant to the Chhau Dance, is also funded by the state government. It is the best form of mask dance. For safeguarding Chhau Dance the Sangeet Natak Akademi has taken up specific measures including grants to cultural institutions the establishment of a National Centre for Chhau Dance at Baripada, Odisha.
