Query: The Dvd is very straight forward and easy to follow

The system that Desi Serna uses is very easy to follow and to understand.I was told that the Pentatonic scale is very hard to learn, but Desi Sernamakes the Pentatonic scale easy to learn by taking you from the fist pattern to the fifth pattern at a good slow pace.He's not in a hurry to fly through each scale pattern, but he takes his time to show each finger position.... for all 5 patterns.Once you learn the 5 patterns.......Desi shows you how to connectall 5 patterns across the fretboard and thats just the start.
