n. music composed with advanced structural and theoretical considerations, as opposed to folk music and pop music.
Art music (also known as Western classical music, cultivated music, serious music, canonic music, or more flippantly, "real music" and "normal music") is an umbrella term that refers to musical traditions, implying advanced structural and theoretical considerations and a written musical tradition. The main tradition in the Western world is usually called classical music. In this regard, it is frequently used as a contrasting term to popular, traditional, or folk music (also called vernacular music). After the 20th-century, art music was divided into two extensions: "serious music" and " light music".
