This is merely a suggestion ... but perhaps someone should define culture. Everything that defines a people's identity.   So that could be alot of things. A people's history, music and instruments, dance, food and beverages, clothing styles, architecture, mythology and religion, folklore/legends/stories and such, literature/poetry, the arts, holidays, customs and traditions, sports/games/leisurely activities, technology, etc... THose would all be considered aspects of a people's culture.
