Greetings, Dr. Guitar,

I am currently employed as an assistant to Dr. OM Dreadnought. Dr. Dread, as he sometimes calls himself, cannot personally reply to your post because there is currently a rash of cookie problems on the 'Cat and he doesn't want to ditch my cookie and not be able to get it back and make me have to be a GUEST. Anyway, Dr. Dread says, "That is the most exquisite example of unintelligible musical obfuscation I have ever seen. The author is to be congratulated."

Please note that Dr. D's comments are not my own. Personally, I've always thought that the term "9th chord" automatically implied the presence of the dominant 7th in the chord structure and the term "7-9" is a bit redundant. If the 9th is present in the chord without the dominant 7th it is generally called "add 9". The chord represented by X02200 or, in another voicing, 577400 is "A add 9" and is just a lovely-sounding chord.

Oh, my God! I think I may have inadvertently posted a serious musical observation to this thread. Please pardon me. I don't know what I was thinking.
