Elizabeth Cotten

Elizabeth "Libba" Cotten (January 5, 1893 – June 29, 1987) was an American blues and folk musician, singer, and songwriter.

A self-taught left-handed guitarist, Cotten developed her own original style. Her approach involved using a right-handed guitar (usually in standard tuning), not re-strung for left-handed playing, essentially, holding a right-handed guitar upside down. This position required her to play the bass lines with her fingers and the melody with her thumb. Her signature alternating bass style has become known as "Cotten picking".
