Hi, in this video guitar lesson I explain the basic of Banjo Rolls very common in country guitar. You'll find a couple of exercises on how to practice it and how to develop accuracy.
As you can see in the video, this technique is normally played using a thumb-pick or hybrid picking (flat pick + fingers).

Please check out the other lessons on my website and let me know what you think.
I hope you enjoy it.
