Ethnochoreology (also dance ethnology, dance anthropology) is the study of dance through the application of a number of disciplines such as anthropology, musicology (ethnomusicology), ethnography, etc.
The word, itself, is relatively recent and means, literally, "the study of folk dance", as opposed to, say, the formalized entertainment of classical ballet.
Thus, ethnochoreology reflects the relatively recent attempt to apply academic thought to why people dance and what it means.
It is not just the study or cataloging of the thousands of external forms of dances--the dance moves, music, costumes, etc.-- in various parts of the world, but the attempt to come to grips with dance as existing within the social events of a given community as well as within the cultural history of a community.
Dance is not just a static representation of history, not just a repository of meaning, but a producer of meaning each time it is produced--not just a living mirror of a culture, but a shaping part of culture, a power within the culture:
"The power of dance rests in acts of performance by dancers and spectators alike, in the process of making sense of danceâ€¦ and in linking dance experience to other sets of ideas and social experiences."
Ethnologic dance is native to a particular ethnic group.
They are performed by dancers associated with national and cultural groups.
Religious rituals (ethnic dances) are designed as hymns of praise to a god, or to bring in good fortune in peace or war.
