Maybelle Carter, American autoharp player (died 1978)

"Mother" Maybelle Carter was an American country musician and "among the first" to use the Carter scratch, with which she "helped to turn the guitar into a lead instrument." It was named after her. She was a member of the original Carter Family act from the late 1920s until the early 1940s and a member of the Carter Sisters and Mother Maybelle group.

An autoharp or chord zither is a string instrument belonging to the zither family. It uses a series of bars individually configured to mute all strings other than those needed for the intended chord. The term autoharp was once a trademark of the Oscar Schmidt company, but has become a generic designation for all such instruments, regardless of manufacturer.
