The folk dance of Bihar is known as Chhau dance, which depicts enormous vitality and virility. The word 'Chhau' comes from the Sanskrit root 'Chhaya' meaning shade. As masks form an important feature of this dance it is called 'Chhau', which means mask.
Chhau dance includes certain steps from 'Pharikhanda' which is a system of exercise. This system of exercise has been an important part of training of Sipahis. All the performers hold swords and shields while performing this exercise.(Bihar)
The stages are decorated and brilliantly lit by a large number of torches, lanterns and flickering oil lamps. Ragas of Hindustani music is the main base of the tunes. The musical instruments used are the Dhol ( a cylindrical drum), Nagara ( a huge drum) and sSehnais (reed pipes). The dance is performed by men and boys. As it is difficult to dance for very long with a mask, the dance does not last more than 7-10 minutes.
The three main elements of classical dance, namely Raga (melody), Bhava (mood) and Tala ( rhythmic timing) form an important aspect of Chhau dance. This is because it follows certain traditions of the classical mode. Chhau dance is an expression of a mood, state or condition. They also depict nature and the animal world. Sagara Nritya (ocean dance), Sarpa Nritya (serpent dance), Mayura Nritya (peacock dance), etc., are examples of the different forms of dances. The dance may also consist of themes taken from mythology and everyday life.
Chhau dance is a dance full of vitality and robustness, unlike any of the Indian dances. The entire body and entire being of the dancer is employed as a single unit, as his language. This body language is extremely poetic and powerful. The legs form an effective means of communicating the expression. Although the face is covered by the mask it mysteriously expresses the feelings to be communicated.
In Mayurbhanj, Chhau is performed mainly in Saraikella On the 25th day of the Chaitra month, the Lord Shiva invocated and the dances began.
Chhau is mainly a male dominated art. However in recent years women have taken to Saraikella and Mayurbhanj. The leading exponents of the Chhau in Saraikella have been the royal princes in Mayurbhanj, the lower classes, the rabble and Purulia farmers, tillers and the like.
