Start with what people pass on
I hear culture used to mean taste, entertainment or a visual style. Those can be part of it, but the word holds more than the arts. Research on cultural evolution studies how information and behaviour pass between people through social learning. That gives me a useful starting point because it asks how knowledge moves, not only which objects get displayed.
