Some time back I wrote an article describing the different uses of 4-string, 5-string, and 6-string banjos. http://www.creekdontrise.com/acoustic/b ... banjos.htm
Recently I saw some five-string banjos that were better suited for clawhammer and other strumming-heavy styles than they would be for Bluegrass being advertised as "Bluegrass banjos." I'm sure the manufacturers were just trying to keep totally clueless people from buying 6-string banjos and expecting to learn Scruggs-style on them. But I thought it was worth pointing out that Bluegrass performance requires a certain kind of banjo, preferably with metal tone rings and other features to boost the volume and the ring.
So here's an article on that:http://creekdontrise.com/acoustic/banjo ... _banjo.htm
