Example 1 is in the key of D and employs the reverse banjo roll that was discussed in part 2 of this series. Try to let all the open string notes sustain as long as possible.
Example 2 is way up the fretboard and in the key of E. This resembles a reverse banjo roll as well but starting on the M (middle finger of the right hand). I use this one quite a bit since it sounds a little out of the ordinary, a little less predictable.
Example 3 is in the same area of the fretboard as the previous example, but with some wider right hand leaps and a bluesier sound combing the flat third and major third.
Example 4 is a nice looooong rockabilly lick in the key of E. It employs some forward banjo roll action and some reverse on the way down. Try to play this one as fast as you can over a "Mystery Train" kind of groove.
Examples 5 thru 9 use the same type of descending open string lick that is altered to fit into 5 different keys. It's a good idea to have a bunch of these worked out for multiple keys just in case. Pay close attention to the right hand fingering on these. Pop the hybrid picked notes hard for a nice chicken pickin' effect.
