Ed,
i really don't want to start a big debate on this. You have a book to promote and I understand that. I'm writing my own books right on the subject. It comes from 30 years as a teacher at university and gigging at the very top level. I just don't subscribe to this kind of advice without warnings or alternate solutions.
BTW,I hope you are aware of how weird it sounds when you mention that playing that is ok for students at the beginner level AND Ron Carter(???).
Sorry, I can't not mention it, professional consciousness.
I am not here to promote my book. The forum people chose it on their own, as have many thousands of people over the past 17 years. They've bought it already, I have no need to sell it to them again.
Try this: One measure of Dm7 moving to G7... play D-G#-A-F# to G. Now play D-G#-A-F to G. Personally, I think the first way sounds smoother as a line, and the fact that the "offending note" happens on beat 4 renders it essentially harmless to the chord quality which immediately passes to the G7. If the F# bugs you - don't use it.
I'm glad you feel well qualified to teach and you are free to criticize whatever you want about my methods. I am not so insecure about my work that I can't take some questioning.
However, I will say this once more and leave it at that: Using a chromatic approach from a minor chord that is the major 3rd is perfectly acceptable for anyone - Ron Carter, a beginner, my aunt Gertrude... anyone. If it sounds good for Ron Carter, it will sound good for my aunt as well, though I think she swings a little harder.
You can't subscribe to this advice without warnings or alternate solutions... what type of warning exactly? No one has lost a gig, been humiliated in public or suffered bodily harm as a result of using this musical technique.
Alternate solutions? The entire book is full of them. So it seems to me you are simply pushing a point for the sake of something else. Ultimately, one note here or there does not make or break a walking bass line, but regardless, I still think it sounds better.
If you assume that I tell people this out of a lack of professional consciousness, you are being more than a bit presumptuous.
Now, can we move on from this time consuming nit-picking?
