I took a banjo class in a community education program for a few months two years ago. It focused on bluegrass. I got so I could play a few songs, but to get really up to bluegrass picking speed would take me probably a couple of years or more of daily practice. I have been thinking of switching to clawhammer style which I have read is much less demanding, but I haven't heard much music in that style. To compare bluegrass banjo to guitar (if that will help Coralena), the banjo right hand is considerably harder but the left hand is considerably easier (for me at least).
