Guitar : Folk Music
The Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music.Traditional folk music has been defined in several ways: as music transmitted orally, or as music with unknown composers. It has been contrasted with commercial and classical styles. One meaning often given is that of old songs, with no known composers; another is music that has been transmitted and evolved by a process of oral transmission or performed by custom over a long period of time.
A consistent definition of traditional folk music is elusive. The terms folk music, folk song, and folk dance are comparatively recent expressions. They are extensions of the term folklore, 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. Traditional folk music also includes most indigenous music.
