The tenor banjo is the most popular member of the four-string banjo family. It is tuned C G D A just like a mandola, a viola or a tenor guitar. It provides the alto voice to the jazz band and excels at both rhythm and lead functions About the banjo our beloved friend, Wikipedia, says: “In almost all of its forms, banjo playing is characterized by a fast arpeggiated plucking, though there are many different playing styles.” Did you know that? I didn’t know that.
