I've finally found a great teacher for bass and been taking lessons for a couple of months. We're doing a walking bass book that's freakin' awesome and he wants to me to write out some of my own walking lines over a 12-bar jazz blues. Here's the thing - I know one major scale shape. And while a lot of the walking stuff we've been studying is chromatic in nature, I really feel like I don't really know my way around the fretboard enough to walk smoothly. I'm thinking that if I can get the major scale down and be confident in quickly finding scale tones my walking will improve 100%. I'm starting to think that learning scale shapes isn't the best way to go. Maybe I need to learn the notes in the major scale for all the chords. I can't seem to memorize the shapes and apply them wherever the root happens to be that I'm shooting for. What do you think? Keep trying to learn the shapes or learn the notes??
