Odissi is one of the eight classical dance forms of India. It originates from the state of Orissa, in eastern India. It is the oldest surviving dance form of India on the basis of archaeological evidences.The classic treatise of Indian dance, Natya Shastra, refers to it as Odra-Magadhi. 1st century BCE bas-reliefs in the hills of Udaygiri (near Bhubaneshwar) testify to its antiquity. It was suppressed under the British Raj, but has been reconstructed since India gained independence. It is particularly distinguished from other classical Indian dance forms by the importance it places upon the Tribhangi (literally: three parts break), the independent movement of head, chest and pelvis and upon the basic square stance known as Chauka or Chouka that symbolizes Lord Jagannath.
Kathak is one of the eight forms of Indian classical dances, originated from India. This dance form traces its origins to the nomadic bards of ancient northern India, known as Kathakars or storytellers. Its form today contains traces of temple and ritual dances, and the influence of the bhakti movement. From the 16th century on-wards it absorbed certain features of Persian dance and central Asian dance which were imported by the royal courts of the Mughal era.
The name Kathak is derived from the Sanskrit word katha meaning story, and katthaka in Sanskrit means he who tells a story, or to do with stories. The name of the form is properly katthak, with the geminated dental to show a derived form, but this has since simplified to modern-day कथक kathak. Kathaa kahe so kathak is a saying many teachers pass on to their pupils, which is generally translated, 's/he who tells a story, is a kathak', but which can also be translated, 'that which tells a story, is Kathak'.
