Elizabeth “Libba” Cotten (née Nevills) (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. She played a guitar strung for a right-handed player, but played it upside down, as she was left-handed. 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”.

Cotten was born in 1893 to a musical family near Chapel Hill, North Carolina, in an area that would later be incorporated as Carrboro. Her parents were George Nevill (also spelled Nevills) and Louisa (or Louise) Price Nevill. Elizabeth was the youngest of five children. She named herself on her first day of school, when the teacher asked her name, because at home she was only called “Li’l Sis.” At age 7, she began to play her older brother’s banjo. “From that day on,” she said, “nobody had no peace in that house”. By the age of 8, she was playing songs. At age 9, she was forced to quit school and began work as a domestic. At the age of 12, she had a live-in job at Chapel Hill. She earned a dollar a month, that her mother saved up to buy her first guitar.The guitar, a Sears and Roebuck brand instrument, cost $3.75 (equivalent to $107 in 2019). Although self-taught, she became proficient at playing the instrument, and her repertoire included a large number of rags and dance tunes.
