Attached below you will find a rough draft of a banjo tutor written by George Gibson in the 1990s. In it, George describes in great detail several of the playing styles and techniques which he observed as a youth in Knott County, Kentucky. He also uses his original notation system, which works like a simplified tablature, to lay out several of the most commonly played songs.
