All right, this is a little bit more interesting than just a straight forward chromatic exercise and a little more frustrating :-), so bare with me. Ex1 is a derivitive of the spider chromactic technique taken a step further. This technique is called the "outside" and "inside" technique, because you start with your index and pinky and the next time around you start with your middle and third fingers respectively. Take you time to master the idea before using a metronome, this is a most beneficial exercise. and once you go down all of the frets to the highest fret on your guitar, then you work your way back up as it shows in ex.2. then switch finger positions and experiment on your own and come up with different patters. Good luck, see you next time.
