Now let's combine the index, middle and ring fingers with the alternating thumb patterns. Be sure to take these nice and slow, one at a time. These exercises will challenge the thumb to keep its alternating bass pattern accurate and constant as we add in the index, middle and ring fingers on beats 2 + 4, beats 1 + 3, beats 2 + 3 and finally beats 1 + 4, or any other combination you can come up with. Doing these patterns and exercises will help improve your thumb and finger independence and get you ready for the next stage of patterns. It's all about having control and coordination. Take these patterns really slow at first and strive for accuracy and good tone. Remember the thumb is in charge of the lowest three (6th, 5th and 4th) strings and the index, middle and ring fingers are what will pick the highest three (3rd, 2nd and 1st) strings.
As an example let's play the progression from Jerry Reed's song Jerry's Breakdown with a few patterns. If you haven't listened to Jerry Reed's guitar playing and music I would encourage you to spend some time listening to his playing, you won't be disappointed! Plus you'll hear a lot of the techniques we are focusing on being used in all sorts of incredible ways.
