I have studied jazz standard improvisation techniques from everyone of note from Carol Kaye to Scott Devine. I know all about what arpeggios, scales, modes and chord substitutions to use. My problem is this: How the hell do I keep all this knowledge organized in my head and be able to efficiently pick and choose what I need so I can improvise through a jazz standard. It is like input overload and the output is confused, jumbled, and totally dysfunctional. How do you approach a jazz standard improvisation solo? Do you just play because you've practiced so much that it is natural and has become habit? Do you think about what you will do ahead of time? Do you work things through with the band in practice so you know what to do at a real show? How do you think so fast, especially on the uptempo songs? What are your thought processes for picking and choosing from your repertoire to play through a solo? How do you decide what you are going to do? How do you keep it all organized in your head? I think I have some kind of mental block or something that keeps me from being comfortable with soloing. I don't know. It is so frustrating, (but awe inspiring at the same time) to hear and see a bassist play a solo to a jazz standard and appear to do it efficiently and effortlessly. I've been playing almost 40 years, but when it comes to soloing.......aaarrrgghhhh!!! I just don't get it. In other words, how do you simplify all of your bass playing knowledge to create a solid solo improvisation? For me it is like this...........seeing separate videos one at a time of each of the steps to build a house including the carpentry, plumbing, electrical, etc and thinking, "Yeah, that makes sense. I can do that".....but never seeing the complete video on how to put all these skills together to make the darn house....thinking "So, how the heck do I make a house?" I really look forward to any advice all you wonderful bass players have to share and I thank you ahead of time. Thanks everyone!
