folk music

Folk music is a term for musical folklore which originated in the 19th century. It has been defined in several ways: as music transmitted by word of mouth, as music of the lower classes, and as music with no known composer. It has been contrasted with commercial and classical styles.
Since the middle of the 20th century, the term has also been used to describe a kind of popular music that is based on traditional music. Fusion genres include folk rock, electric folk, folk metal, and progressive folk music.The terms folk music, folk song, and folk dance are comparatively recent expressions. They are extensions of the term folk lore, which was coined in 1846 by the English antiquarian William Thoms to describe "the traditions, customs, and superstitions of the uncultured classes. "The term is further derived from the German expression Volk, in the sense of "the people as a whole" as applied to popular and national music by Johann Gottfried Herder and the German Romantics over half a century earlier.
