I recently got this book because I want to build my knowledge on walking bass. The only thing in here that has been confusing me is in the last two bars of each example there seem to be some slightly out of place chords from the rest of the progression. I saw the note he made in the introduction and I think it has something to do with this, but I still don't get why he uses them and it is kind of confusing me as to why they are there. Anyone who could help me with this, it would be much appreciated.
thanks
