Wikipedia has an entry too:
Art music (alternatively called
classical music,
cultivated music,
serious music, and
canonic music[1]) is music considered to be of
high aesthetic value.
[2] It typically implies advanced structural and theoretical considerations
[3] or a written musical tradition.
[4] In this context, the terms "serious" or "cultivated" are frequently used to present a contrast with ordinary, everyday music (i.e.
popular and
folk music, also called "
vernacular music").
[2]
"Art music" is mostly used to refer to music descending from the tradition of
Western classical music. Musicologist
Philip Tagg refers to the elitism associated with art music as one of an "axiomatic triangle consisting of 'folk', 'art' and 'popular' musics".
[5] He explains that each of these three is distinguishable from the others according to certain criteria.
[5] According to Bruno Nettl, "Western classical music" may also be synonymous with "art music", "canonic music", "cultivated music", "serious music", as well as the more flippantly used "real music" and "normal music".
[1] Musician
Catherine Schmidt-Jones defines art music as "a music which requires significantly more work by the listener to fully appreciate than is typical of popular music". In her view, "[t]his can include the more challenging types of jazz and rock music, as well as Classical".
[6]
The term "art music" refers primarily to classical traditions (including contemporary as well as historical classical music forms) that focus on formal styles, invite technical and detailed deconstruction
[3] and criticism, and demand focused attention from the listener. In strict western practice, art music is considered primarily a written musical tradition,
[4] preserved in some form of
music notation, as opposed to being transmitted orally, by rote, or in recordings (like
popular and
traditional music).
