This is sweep picking combined with 8 finger tapping and to be able to do this properly you have to learn and master the technique where I slide the pick up the thumb using my index finger, this movement enables you to use all four fingers on each hand to do the 8 finger tapping technique. This is obviously not an easy technique but its a technique I developed many years ago to combine those two wonderfull techniques, sweep picking and 8 finger tapping

The way you can implement this very advanced technique is to start it in the sixth postiion of the Major scale and then you en it in the first position of the Major scale. This way you make use of the the Tonic parrallel concept which is always a sure winner
