Mark's book is great, but I think you need same salt to go with just about any theory book. Check out the section in that book on minor harmony and the implied scales that go with a minor ii - V7alt - i...for that section, I needed both salt and pepper. (No disrespect to Mark implied AT ALL, I just hear things differently). But it's a difficult task to try and codify sounds that are generally played with the amount of freedom inherent in this music - you always end up walking a fine line between understatement on one hand and pedantry on the other.
Indeed. Perhaps a "learn the rules so you can forget them" kind of approach would be called for here?
Which brings up an interesting point: should the chord symbol reflect only what notes should be in the chord voicing, or should they also reflect the "implied scale" to be played over that voicing?
Until I started reading Levine's book - I would have said the former. It's that book that's got me thinking about the idea of such a tight link between chords and scales. There's an example he gives early on in that book (when discussing modes), where, as an example of a conversation between two musicians, he says something like:
Musician 1: What's the chord in bar 2?
Musician 2: F Lydian
For me that was sort of a "whoa there... but F Lydian isn't a chord!". I'd never really thought of chords and scales as being so inextricably linked that you could use them interchangeably like that.
Until recently, I didn't think that 7b9 implied half-step/whole-step diminished (and therefore, #9 and #11). I thought it meant just that; dominant 7th chord with b9. Of course, I would often voice it with altered extensions (often #9, sometimes #5) -but I didn't think that 7b9 implied #9, #11 and natural 13 in itself. The way Levine describes it - 7b9 is shorthand 7b9,#9,#11. I'd never thought of it quite like that.
This is particulary pertinent to the 7#11 sound, which is usually a "non-resolving" dominant in the traditional sense. In many cases where the #11 is implied by the overall tonality I'll choose not to write it in the chord symbol if I don't want the harmony player to play that tension in the chord every time - especially with younger or beginning players, I think it's more important to get a feel for when an alteration needs to be voiced or not.
