Willie Myette was one source for this #4 thing...

Someone mentioned Russell's Lydian Chromatic Concept. I have an old copy but I must say that I found it hard to read.

what I got from him is that if you stack Perfect 5ths then you get a Lydian scale, not an Ionian. C, G, D,A, E, B, F# (not F). Perhaops this has something to do with it?

I can see the #11 on a major chord in the IV position, no problem.

Also, building from Lydian rather than Ionian, in perfect fifths, you can get a sequence where the Lydian is the brightest scale, the Ionian second brightest, then myxolidian, dorian, aeolian, phrygian, then LOcrian. Each scale changes by one note, and darkens.

the order is:
Lydian (#4)
Ionian (THE #4 is naturalised)
Myxolidian (the seventh is flattened)
Dorian (the third is flattened)
Aeoilian (the sixth is flattened)
Phrygian (the 9th is flattened)
Locrian (THe fifth is flattened)

The roots go down in fourths/up in fifths as do the alterations.

This makes sense to me (somehow) but I have been unable to relate it to alterations

Perhaps the #11 extension is really a Lydian thing, unless you looking for dischord?
