Our book distinguishes between world concert and ritual dance and folk dance.
What distinction does the author make?
World concert and ritual dances are never performed for the general public, and
folk dances are always performed on stage for public audiences.
World concert and ritual dances are only performed by men, and folk dances are
only performed by women.
World concert and ritual dances are only performed by women, and folk dances
are only performed by men.
World concert and ritual dances are usually performed for an audience (public or
private), and while folk dances might have an audience, their main purpose is
participatory (as a social activity).
