Which term refers to non-religious music intended for entertainment?

The term that refers to non-religious music intended for entertainment is secular music. Secular music encompasses a wide range of musical styles and genres that are created for enjoyment rather than as part of religious worship or ceremonies. This includes popular music, folk songs, and various forms of entertainment music that are often performed in social settings.

In contrast, liturgical music is specifically associated with religious worship and is used in ceremonies and rituals within various faith traditions. Gregorian chant refers to a style of plainchant used in the Roman Catholic Church, characterized by its monophonic sound and Latin texts, and is inherently spiritual in nature. Organum is a form of early polyphony that developed from Gregorian chant, but like chant, its roots are in liturgical practice and not in entertainment. Thus, secular music distinctly represents a genre focused on leisure and artistic expression outside of religious contexts.
