Abstract
A banjo, made almost entirely of wood, eliminates most metal parts of a traditional banjo. The neck is bolted to the body, improving sustain. The body consists of a drum assembly bolted to a resonant tone chamber. The resonant tone chamber consists of a thin back, thin rim assembly, interior flange ring, thin decorative cover and tone ring. The interior flange ring provides mechanical strength to the resonant tone chamber and anchors the drum assembly. The drum assembly consists of a banjo head and a tension hoop. The banjo head snugly fits over the tone ring, and is tensioned via a plurality of bolts that secure the tension hoop in the drum assembly to the flange ring in the resonant tone chamber. A sound port cut into the rim assembly provides sound to a player. Sound holes cut into the decorative cover project sound from the resonant tone chamber toward an audience.
