I am a newcomer to 5-string banjo, but since I play guitar and have had a few lessons I have a good foundation for understanding the instrument. I had been playing, and have recorded, "What Shall We Do with the Drunken Sailor" with a friend using guitar in Em. I now want to add banjo, but I don't know which tuning and capo position would be best to be able to play the chords Em, D, and G (as strange as that sounds). As I now have a long-neck banjo, I don't know how I should go about finding the right place to play the song.

What are your suggestions?
