Fourth Fret Exercise for Bass Guitar

"Hi! I am Carl Shepard with expertvillage.com and now we are going over another exercise similar to the spider walking or other tab exercise which would be fourth frets of your bass for each string and instead of doing them on a row we are going to go from the first fret to the third fret, then the second to the fourth. You do that for each string and I am using a different finger for each fret. So coming back down makes it a little harder and it is definitely coordination challenging as far as this exercise goes but make sure you are using your index on the first fret and your middle on the second, ring finger on the third and pinky on the fourth."
