Elizabeth "Libba" Cotten (January 5, 1893 – June 29, 1987) was an American folk and blues musician. She was a self-taught left-handed guitarist who played a guitar strung for a right-handed player, but played it upside down.[4] This position meant that she would play the bass lines with her fingers and the melody with her thumb. Her signature alternating bass style has become known as "Cotten picking".
