Time for some tapping folks!!!
I have purposely played this in the video with an even tempo and rhythm just so as to make it easier to learn. Once you have the whole pattern, that is after you have dissected it and practiced each part slowly, then you can apply the subtle changes in rhythm notated in the score. More often than not you will find 12 note groupings but there are changes here and there so make sure you take note of where the changes in rhythm occur.
As you will be skipping strings at the beginning of the pattern it is essential that you keep things as clean as possible by damping unwanted strings with both the left and right hands.
Great! All that awaits you now is the backing track.....
