Dance by ethnicity or region
India
During the first millennium BCE in India, many texts were composed which attempted to codify aspects of daily life. In the matter of dance, Bharata Muni's Natyashastra (literally "the text of dramaturgy") is the one of the earlier texts. Though the main theme of Natyashastra deals with drama, dance is also widely featured, and indeed the two concepts have ever since been linked in Indian culture. The text elaborates various hand-gestures or mudras and classifies movements of the various limbs of the body, gait, and so on. The Natyashastra categorised dance into four groups and into four regional varieties, naming the groups: secular, ritual, abstract, and, interpretive. However, concepts of regional geography has altered and so have regional varieties of Indian dances. Dances like "Odra Magadhi", which after decades long debate, has been traced to present day Mithila-Orissa region's dance form of Odissi, indicate influence of dances in cultural interactions between different regions.
