As most of us know, standard tuning for a 5-string banjo is an open G tuning (G,D,G,B,D). Open G tuning means that if we strum all the strings without fretting any of them, we will be playing a G chord. Open G is a great tuning, but there are many other ways you can tune your banjo as well. By tuning it differently, you can get a completely different tone out of your banjo. It also can make it easier to play certain songs in different keys.
