Speaking of the Rosetta Stone.....
Seriously though, thanx for going the extra mile on this. I had seen this on the wikipedia but scanned through it quickly. Just now I've had a chance to look closer at this Luis Miguel book, printed in Spain, and I've noticed by analyzing the notes of the piano score that they are using a a 7+ to indicate a Maj7 chord. Holy cow! If it wouldn't have been for the piano part being written out, I'd never ever have guessed this one. On top of that, if you look at the wikipedia they show a +7 as a Maj7 and the augmented 7 as +7 OR 7+. If this isn't enough to make you start talking to yourself I don't know what is.
Geez, I have always read a 7+ as an augmented 7, which goes all the way back to the first fake book put out in 1948. I figured this was the standard. I also figured that if it showed a +7 it was the same thing, which is what they say in this encyclopedia.
So, in Spain then, apparently, a 7+ means Maj7, which is not what it says in the wikipedia.
I can't wait to see what they use for augmented 7ths, or if there are any other little surprizes.
