Chris Fitzgerald said elsewhere : "One of my pet peeves about jazz is the degree to which the walking bass texture is considered to be an absolute staple for such a large percent of the music. It boggles my mind sometimes when I stop to consider that you have almost an entire genre built upon the same basic groove. Personally I like those bass players who mix it up a bit, but this is a subject way too large to get started in this thread.... " So why not have a whole thread devoted to this then? My personal view is that we ought to be able to do more and especially on bass guitars with lower actions, greater playability, added strings, etc. we can do more. So how about a discussion of what we can substitute instead and maybe even some examples of where this happens in Jazz pieces or recordings? I mean Jaco always comes up as an example, but there must be others and what is their favoured approach to an improvised, non-repetitive line that isn't a walking line?
