Folk music, like folk literature, is of oral tradition. Folk music is learned through listening rather than reading. The question of whether a song/piece of music is folk music depends on a certain criteria based on patterns of transmission, social function, origins, and performance. The infamous folk artist Elizabeth “Libba” Cotton only needed to hear a tune a couple of times to learn it. She is also a self-taught left-handed, upside-down, banjo and guitar player which made her so profound in the genre.
