"Folk" music (or traditional songs) are those that have grown up among country people and have been handed on from singer to singer, and from generation to generation, without being written down or notated. As with many traditional songs, nobody knows who actually composed them in the first place, or when they were composed. As with most folk music, everybody who sings them makes a contribution - for each singer will make, either by accident or design, some tiny variation to the words and/or melody. A folk song therefore may become the "musical expression of a culture or community".
