This is nothing more than a line that I have used in order to get my fingers to stretch and move a bit quicker. As with my other lessons, I admit that I use open strings more than I should. Therefore, you may wish to use fifth fret as opposed to open string. This also gave me a chance to try some straight forward rock type lines with a tiny bit of funk syncopation. It's an early attempt to add some lines to my own repetoire.
