Folk music is a term for musical folklore and is, as the name implies, the music of the people.
Originated in the 19th century however some of the earliest folk songs rose from slave fields. Folk is considered more of a tradition than entertainment.
Folk music has been the music of the working class. Folk songs range in subject matter from war, civil rights, work, economic hardship and love.
The 20th century brought folk music back as workers struggled and struck for child labor laws and the eight-hour working day. Workers would gather round in churches, halls and living rooms to learn songs which helped them through the rough work environment; these songs described hardship but were however full of hope.
In the 1960's folk music became incresingly more popular with the likes of artists such as: Bob Dylan, Joan Baez and Niel Young whose work dealt with anything from love, war, work and play.
