@Don Kasper what is your proposed solution? I remember you taking Bromberg to task on using incorrect RB changes on his album. I don't have an issue with that - at a certain level RB changes shouldn't be used.
What about the reality of RB changes in the world and that being the common versions of the tunes people know? How do you propose that be addressed?
People have been saying RB changes are wrong and demonstrating it for decades.
Back when I started (in the mid 70's), you had to have the vinyl recording of a tune, or know someone who did - and would lend it to you (good luck!), as it was not po$$ible to own a version(s) of every tune that you wanted and needed to play. So, the Real Book was a useful, though sloppy and inaccurate, tool - as I soon found out.
These days, a version, or multiple versions, of a tune can be accessed in a matter of seconds, (for Free), so there is a real learning opportunity for musicians to access and hear a version of a tune that actually "exists"...unlike so many of the RB fiascos that do NOT exist, and are simply WRONG. For instance: there was no version of Dolphin Dance, (that I'm aware of), with the many ERRORS and Omissions (Wrong Pedal points, wrong changes, etc.) that existed prior to the RB publication. The RB's 4 bars of pedal "B" instead of a pedal "E" is NOT an "arrangement"... it is plain Wrong. (Yeah...I said it!)
The first chord of Blue In Green is Gmin6 9, and calling it "Bbmaj7 #11" is NOT an "arrangement".
The missing 4 bars in the bridge of Desafinado is NOT an "arrangement".
I could go on.
My problem with the RB, is NOT the Key of Autumn Leaves, (I agree - it's solid and it's correct), but rather, the many Errors and Omissions due to unqualified "transcribers" (I'm using this term very generously), and the obvious lack of any oversight, editing, or proofing by qualified/actual musicians. It's not even funny that this was (apparently?) used as a textbook.
My solution?
Use the RB or any other book or chart, to compare with an actual recording - make (many!) corrections to your RB, and begin transcribing specific versions of tunes that are NOT in the RB. Can't hear changes well? Spend some time with the pianist or guitarist in your group - they are always further along Harmonically than most bassists. Find a pianist or guitarist to take some lessons with - not for your bassplaying, but for your Harmonic awareness and Harmonic ear-training.
Given the amount of easy access and technological advances these days - (there is a thing called a "....Slow Downer", apparently?), there is no longer any excuse for folks to be using AND "learning" lame or stock or wrong changes.
We all talk about improvised music being "of the moment" and "creatively free", but if you can't hear the sound of what is actually present on a recording, (a recording that you can analyze/stop/slow down/listen to... over and over), what makes you think that you'll be able to function "creatively" "of the moment" in a live situation?
I would much rather hear someone play who has listened to, immersed themselves in, written up, and studied 10 tunes, than someone who has downloaded 2800 generic (or worse!) charts of tunes on an iPad. (Yes - the "easy access" IS a double-edged sword, as is most technology. Hey - I'm not an Amish Luddite.)
If anyone is wondering if this is " the Hill I Want to Die On...", the answer is Yes.
Thanks for your time and interest, Damon. (and be careful on your new BIKE!!! for pete's sake!)
