Playing a tenor banjo is very much like playing a mandolin. I bought two second hand instruments two years ago when I turned 70, One of the banjos was a restoration project.
I was fairly enthusiastic to begin with and made fairly good progress at first then I kinda lost interest once I completed the online course. There are lots of fiddle tunes played on the 5 String. Banjo. Soldiers Joy is fun to p;lay in Drop C tuning, Capo up 2 frets and your in drop D, So you can play that with your fiddler. Go check out the TABs on the Fiddle Hangout there’s some great TABs there with BANJO tabs accompanying fiddle. Also check on the Banjo Hangout for TABs by Sean Ray I am sure Sean has some rolling backuo TABs to accompany fiddle .
