I recently came into possession of a Washburn 5-string banjo. I play guitar--purely for fun-- and really don't have an interest in learning how to play the banjo the way it "should" be played but I've been told I can remove the top string and tune the remaining 4 just like the bottom 4 strings on the guitar and finger it just like the guitar. Does this work? And is it what's known as "Chicago Style"?

Thanks for any input.
