About Scales
This lesson is all about four note Arpeggios and in this case the A Major seven and the E Dominant seven, as I explain in the video you can easily incorporate it into the A major scale or of course the Major scale in general, start it from the first step of the Major scale, regarding the technical stuff

Technique
As you can see I combine Tapping using two fingers and in this example I use the long finger and the Little finger, this helps me easily go into the Sweep picking technique without any breaks in the flow of the notes which is one of the most important aspects of this technique, you will also be helped by getting used to play on the fret board with this technique for easier combination of the techniques, in this case Sweep picing and Tapping with two fingers
