Banjo guitar is a term often applied to six-string banjos, a century-old banjo configuration that was an alternative to the four-string jazz banjo. (Johnny St. Cyr's six-string banjo can be heard on some King Oliver recordings.) Less widespread than its 4- and 5-string brethren, it was reintroduced by Deering and others in the latter part of the twentieth century. By then, the 5-string banjo had achieved such dominance that most people using the term "banjo" meant "5-string banjo," and most people hearing them knew exactly what they meant.
