Right now I'm trying to learn how to play walking bass, so I bought a book called "Building Walking Bass Lines" by Ed Friedland. I'm not really sure how I should practice, since there are so many different ways to play a walking bass line, even when playing basic stuff. So far, the book has covered playing over a blues progression using the root, the fifth and the octave and using either chromatic approach notes or dominant approach notes. I wanna be able to play as varied as possible so I'm trying to cover as many variations using the different approach notes as possible, but it is taking quite a lot of time and effort. Right now I'm writing down all the different variations you can do using the root, fifth and octave and the different approach notes in different keys, so that I'll be able to play as varied as possible. What is the most effiecent way of practicing this? Does anybody have any experience with this book? How long did it take you to work through it? I'm new to this jazz and blues ordeal so any advice regarding practice from you jazz cats is appreciated Thanks in advance!
