As promised, here is the first of my High-Def reshoots on the topic of Sweep picking:

Sweep Picking Series 1: The Basics
http://www.guitartricks.com/tutorial.php?input=985

This one covers the basic technique of sweeping using a chord progression of major triads & then one of minor triads. So you get the basic idea, then apply it to major & minor chords, then move it around the neck.

Finally, you get to practice along with a backing track at a slower speed first, then a little faster!

I have five more tutorials on the way that will build on this first one, getting gradually more advanced. Have fun sweeping. :)
