Every jazzer starts off learning "Autumn Leaves." Everybody knows that, and unsurprisingly my teacher started me on it. Now I can do 2-5-1s all day. My teacher also got me going on "All the Things You Are" so I could learn to negotiate key changes. What would Talkbassers consider to be some other really good tunes for learning walking bass techniques? Or, should I just get a Sher Realbook and start learning out of that?
