Folk music

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. Certain types of folk music are also called world music.

Starting in the mid-20th century a new form of popular folk music evolved from traditional folk music. This form of music is sometimes called contemporary folk music or folk revival music to distinguish it from earlier folk forms.This type of folk music also includes fusion genres such as folk rock, folk metal, electric folk, and others.
