A few weeks ago, I was watching Gary Willis' video that he did with Scott Devine at Scott's Bass Lessons, and one of the things he showed, when discussing his technique is, when soloing, the importance of shifting hand positions on the neck, horizontally. I think he mentioned something about making sure he doesn't play more than 4 or 5 notes without a position shift. I sat down and just tried that technique, and it reinforced something I've known for a long time... even after playing 35 years (I'm no slouch, been playing semi-pro for 2 decades), I do tend to be limited, more than anything else, by my lack of good horizontal movements, I think it really limits me, melodically - it keeps me 'bound to the box', so to speak, as well as makes me tend to focus too much on the tonic. So, I was wondering if any of you had some good advice/technique/exercises for getting better horizontal movement technique. I know about learning scales up and down the neck, I generally have no problem doing that, but it's more fundamental, for me, about re-envisioning the way I approach the fretboard, overall, so I'm looking for something along that lines, not just running scales. I play 5 and 6 string. I've been stuck for a long time on this, without fully realizing how much. Thanks, in advance.
