In the Western classical music tradition, Lied is a term for setting poetry to classical music to create a piece of polyphonic music. The term is used for any kind of song in contemporary German and Dutch, but among English and French speakers, lied is often used interchangeably with "art song" to encompass works that the tradition has inspired in other languages as well. The poems that have been made into lieder often center on pastoral themes or themes of romantic love.
