I guess I am not really sure even what the question is, its a funny thing but I find with music the instant you find the question, then the answers there too...

Its about codifying chord extensions/ chord tensions. I am trying to find a way of organising my theory about them. Many musicians just think that the tensions notes give tension and that's it. But is there more to it than this?

It seems the 9th and its little brother the 13th can go with any chord major dom or minor, but what of the flat 9, the sharp 9, the #4 and the b5 - is there any kind of sense to how you use these, or do you just bung them in anywhere when say using a dominant 7th?

I hope people can understand what I mean, is there any kind of categorisation or methodology associated with the extensions?
