Hi Bonnie,If I may add my two cents worth -- don't make playing the banjo become work. Play because you enjoy playing.
Practicing two hours a day is not necessary, although there was a time where I would have said the same thing. Now when I pick up the fiddle I first decide what I wish to do with the time I have. If I have only a few minutes, I may choose to learn a new tune. If I have more time, I might get into some of my clssical "studies". I believe that you practice, work on techinque, run scales and the sort when you have quality time in which to do so. The best advice I can give is to pick up and play the instrument once every day,-- even if it is for only a few minutes.
I noticed in other threads you were looking for fiddle tunes. I have tonnes. I can also help you to learn songs by ear. Give me a shout if I can help. I'd be willing to show or teach you any tricks I use to learn songs.
