Explanation:

- Correct Answer: Nonmaterial Culture

- Songs, languages, and orchestral performances are intangible creations. They are concepts, customs, and shared meanings developed by a society, representing nonmaterial culture.

- Material culture refers to physical objects, resources, and spaces. These are tangible items like buildings, tools, and artwork. Songs and performances are not physical entities.

- Mores are norms that are widely observed and have great moral significance. They are related to societal norms and ethics, not specifically artistic expressions.

- Proprietary culture isn't a standard anthropological term. It suggests proprietary rights, often in intellectual property, not cultural expressions.
