Sounds from the banjo seem to me to be like musical rain.
The surge in popularity of bluegrass music has certainly brought the banjo to the ear of a new generation of listeners.
In a relatively short time, you can be busily running your right hand fingers through those charming sound patterns known as rolls.
There are a number of great introductory books that will gradually build your skill and sense of ease in playing this lovely instrument.
Also, I have written several exercise workbooks for those new to the banjo that will speed your getting to know the fingerboard and manipulate both your right and left hand fingers.
