Synopsis from archive.org:
Presents the origin of the banjo, the development of southern folk music and its influence upon Americans. Pete Seeger plays his banjo and narrates the story.
"Fine views of the "back to the simpler past" movement of American folk music before, just before, it was discovered by the main stream. It gives a glimpse into what the hootenannies were really like in the folk underground in New York...." (vteach)
Although both archive.org and imdb.com give the date of this film as 1947, the film's (presumably lapsed) copyright date is given as 1946 (in Roman numerals).
